Want to quite car down before moving.

[john.thompson068]

I just saw the new apartments I am probably moving into and they are not the greatest but right now I am on a very low income. I would feel much better if my car was not super loud like it is now with the Flowmaster 50 series. I want to draw as little attention to my car as possible even though it will be kept in a garage somewhere on site. I am a little on the paranoid side about my car.

Option 1

Buy Super Turbos even though I don't really like my exhaust making so many tight turns even though they are suppossed to outflow Flowmaster 50 series. These are 45.99 a piece, but something doesn't seem right about the price and the performance.

Option 2

Retain Flowmaster 50 series and add Super Turbo mufflers in front of Flowmasters. These are 115 a piece and are straight through type mufflers with a an offset in center out perforated tube with packing construction.

Option 3

Retain Flowmaster 50 series and add Super Turbo muffler bullet design muffler in front of Flowmasters. These are 70 a piece and have the same straight through design construction.

Option 4

Retain Flowmaster 50 series and have Magnaflow Glass Packs built into the tailpipes as they pass under the trunk. These are 44.99 a piece.

I don't believe options 2 thru 4 will hurt existing performance since the exhaust gas is simply going through a pipe just like it does now, only now it will pass over a bunch of tiny holes with packing material on the other side. Something doesn't seem right about the performance of option 1.

The car currently has a 440 pushing 540 hp, spins to about 6000-6500 rpm, 1 7/8 Hooker competition headers, 3" exhaust, H pipe, Flowmaster 50 series, and tailpipes out the back. I would like to try quiter anyway because it will still sound good and I won't have to worry about the car pissing off neighbors as much here or in an actual neighborhood one day as well as drawing as much attention from the cops should I accidently gas it when one is around.

You decide. Or if you have an alternative option post that.

Id say go with the bullets and put them behind the tail pipes will quite down the exiting sound I would think.

is there a possibility to rent a garage not onsite, but nearby?

I could put the car back into a nearby Public Storage for about 110 a month. Garage on site is 95 a month. It is nice having the car in a garage though since you can't access public storage past a certain hour in the evening. Also, the 10 x 20 at public storage is barely big enough to fit a car into at all. You can barely open the door to get out if you park all the way to one side and there is no room left in front of or behind the car. Working on the car there would pretty much not be happening. Also, driving the car later in the evening and at night would not be happening.

I'm with you on the noise thing. Every time I lean on my Belvedere I look for cops! For my 71 Ranchero I used a set of these http://www.summitracing.com/parts/WLK-17718/ and the car was really quiet and made it a pleasure to drive. Or you can add a glass pack as a resonator. I did that on a car I built for a buddy and it made a huge difference.

Just looked at the Thrush Turbo mufflers and they seem even more restrictive than the Super Turbo. There are not even any bends inside of the Thrush before the exhaust gas is forced to go around and back down and then back up and out. Jegs has nice cut aways of all the mufflers. I recall in my other thread about 4 mufflers exhaust that you did say adding glass packs as resonators made a huge difference in that car. As of right now, I am leaning toward trying out the longest glasspacks since they cannot possibly hurt performance and are the cheapest option. I would also have my tailpipes bent down at the end instead of pointing straight out of the back. Perhaps if they are pointing down at the ground it will redirect enough sound downward to help also. Plus, I noticed that my exhaust tips spray moisture onto my bumper until the car is warmed up which is not very functional.

Glasspack resonators get my vote if you ever want to remove them it's at the rear and just requires tailpipes. I personally don't care about disturbing my neighbors they have disturbed me many times besides most of them are hotrodders or useless loosers. Our motto here at the redneck garage is, it ain't worth havin if ya cain't hear it.

I hear that motto loud and clear. I wouldn't want a quite muscle car either. This one could be quited down a little bit though and it wouldn't hurt. The other night, I barely wanted to accelerate past the fire station I turned around in front of because I figured they might be trying to sleep. I don't want to be feeling all paranoid like that. Especially when I pull into a dead quite neighborhood in the middle of the night. I used to not care about anybody, but things have changed over the last decade. Plus I want to move into one of those new fancy neighborhoods one day with the homeowners association and all that. I had a lady in one of those places tell me my car was too loud after she walked from over 100 feet away from the pool area. What a stupid and rude woman. I have had a few people tell me my car is too loud over the years, even people that like the car. When it comes down to it, all three of those people were complete idiots, but in a way I guess they are right. I am always having people I know comment about how loud the car is and it becomes annoying when all people can say about your car is how they hear it coming or going from way down the street. I have been warned twice over the years by cops about speeding only because the car sounds so mean and fast even when barely accelerating. The stupid property manager of the place I am moving out of chased me down in her golf cart to tell me to slow down after I crept past her on the way to my garage. I didn't even hit 10 mph between all the speed bumps and all this after I stopped and waved her across the street in front of me after she was getting ready to cross the street after showing someone an apartment on the other side. I see people drive through here at 30 mph every day, but since there cars don't make a sound no one seems to care.

True, but with quietness in the $50.00 price range usually comes restriction. Even a glass pack resonator will restrict some due to turbulent flow but as mentioned might be your best option.

 

[blackblazer717]

I vote ditch the slowmasters and install a pair of hooker aero chambers. And not worry about the naibors. im sure 60% of them drive rice burners with fart cans. Which imo are much more annoying than a burble of a big block loaping through the complex. Just sayin

 

[djais1801]

what are you trying to attain:
Not getting noticed w/fear of it getting stolen? if that's the case i get you...and would prob put a kill switch in as well. prob change the lock to the garage also.
IF you don't want to be "that guy" in the complex, i'd keep it the way it is, and just lay off the throttle when you pull into the complex.
You think the guy beating his wife next door cares who hears?:argue:

Please explain more about this turbulent flow. Is it a phenomenon in all mufflers? Seems like it would be a standard problem. As long as the muffler pipe is three inches I would not worry about any loss of any power. My car would likely suffer a barely measurable loss with a 2.5" exhaust and a 800 cfm carburetor instead of the 850. In fact, after upgrading from the 318 to the 440, I reused my 2.5" 40 series Flowmasters in my 3" exhaust system. Later I upgraded to 3" 50 series because I wanted 3" mufflers for my 3" exhaust. Of course it made no difference that I could tell. I also started off with a 750 cfm Edelbrock carburetor, but eventually upgraded to a 850 cfm 4150 and I would never be able to tell if it went any faster or not. Similiarly, I would ditch my Hooker competition headers for a set of TTI's first available chance. I guess it all adds up though in the end. I would hate to be down 10 to 15 hp times three for a total loss of anywhere between 30 and 45 hp.

I have a kill switch epoxied up to the top of the inside of the trunk area back by the wheel well. It is really hard to notice. I run it off the solenoid wire which activates the starter. If anyone were to try and take this car and they had half a brain, they would come in with a trailer or tow truck anyway. I know what you mean about laying off the throttle. I agree with you and blackblazer. It is not really that loud regardless, but especially when just loping around through a parking lot. Later at night anything sounds loud. I can hear music from a club a mile and half from my place, the sound of dirt track cars 10 miles away, and the click clack and diesel engines of trains running on tracks three miles away. I just want to tone it down a little bit that is all.

Yeah those rice burners are much louder than my car because they have such an annoying frequency. My car has a deep rumble which is not as loud. I don't think the Aero Chambers will be any quiter than the Noisemasters. Take a look at this picture. Certainly, Aero Chambers alone will not be any quiter than what I run now. Those things look like the intake on the guided missile destroyer I recently served on. The ship had that same kind of design inside the intakes to keep the ship quite despite having 200,000 hp from 4 GTMs plus the 3 GTGs.

I saw a video recently on the different mufflers that flowmaster manufacturers now and to my suprise they seemed to have expanded and included a quieter muffler series. The ones I saw that I was interested in were a round or oval shape and looked like a shorter tube style glasspack. These seemed to be quieter than the 50 series mufflers and might work well toward the end of the pipes by the gas tank like you had mentioned. It is annoying to have people hassle you just because of the sound of your car rather than what you're actually doing (which is usually traveling slower than most).
All the luck to you!

 

[Moparmatt72]

If I had someone tell me my car was to loud that's when you uncork them lol j/k most people can't or don't enjoy the sound of 100% detroit muscle.

The last thing you want to do is use turndowns as these will have the opposite effect. Right now, soundwaves are emitted from your pipes and radiated through the air, where scattering and dissipation occur. With turndowns, all that sound energy that's normally lost as the soundwaves move through air are directed straight down at the road and reflected, making your car even louder.

Oh good catch. I will just have them extend them out another inch or so past the bumper instead of being flush with it. This way the condensation has a better chance of not splattering around on my bumper. As of right now, glass packs as tailpipes sounds like the way to go. Flowmaster actually makes resonators, but they look exactly like a standard muffler, and there is not really any way I will trust Flowmaster to make anything quite. On the plus side, the price for 70 Series Flowmasters is down from 175 bucks a muffler to 115 bucks a muffler now that they have been out for a while. But I know and could tell from watching the Flowmaster youtube video that the 70 series would only be a little bit quiter than the 50 series on a car like mine which is still going to be too loud. However, I may consider replacing my mufflers with the 70 series one day depending on how quite the glass pack resonators are.

Sounds like you have made up your mind,good luck with the greed restricted home one day if apartment managers complaining to you is aggravating wait till you have the H.O.A. complaining about the grass is too high,garage door was open for more than 15 minites,can't park your truck in the driveway,no boats,rv's,kids toys,swingsets,fences,gotta paint your house the same as everyone else ect. I don't live in one but i have heard the horror stories [not for me but neither are apts,town homes ect. Where i live we are not suppose to work on cars i have built 7 since 1990 just keep my place clean and the noise to a dull roar [helps to have cool neighbors].

 

[john.thompson068]

Already called muffler shop for price. Have to call back to see what the part number is on the mufflers they want to sell me cause that guy was busy, but he says $100 a piece installed. $200 sounds a little high since I had an entire exhaust system built with Flowmasters for like $400-$450 or something like that. Some glasspacks do cost almost $100 but that sounds like too much for a glasspack. I am looking at 3" ones on Jegs for $49 a piece, but then there is handling and shipping.
