Hi All,
I have a 68 charger with 383. The car was restored about 10 years ago, but im not sure whats inside the engine (likely stokish cam / 650 carb). I've had doug's 3 inch headers installed a while back, the rest of the exhaust is 2.25 inches (stock) with an h-pipe. I also and electrical cutouts in the first part of the exhaust before the h-pipe. I sort of love/hate my cut outs, at idle they sound dope, at full throttle they sound insane with awesome pops on decell, but in the middle - just driving with them open, they sound like a busted muffler. With cut outs closed, the car is very quiet, like too quiet for my taste to be honest (in the past I had a 73 charger with a mildly built 440 and supertrapp exhaust, that sounded dope, but i don't want it that loud tbh).
On my recent shop visit, i noticed that my mufflers have started to rust out and developed some holes, so its time to replace them. I think i like the magnaflow exhaust, so I have two options.
1. on their website I see an option to buy a headerback 2.5inch exhaust for about $1,000k (would need to be welded/installed, so another $500-600 or so), then I'd probably want to install the cutouts again, so that would add another $500 for the kit and welding.
2. I also see that I can buy just the mufflers, but those are 2.5inch (vs 2.25 that I have on there now), but it would only cost me a total of about $500 to install (about $250 for welding, and $250 for just the mufflers).
So naturally, ideally, I should do option 1, but it would be about $2k. - would i get more hp/tq that I would feel out of this set up? Would sound be noticably better with this option? more importantly, if i do upgrade to 2.5 inch cut outs, would they sound better and should i install them after h-pipe/xpipe for a better sound (currently, they are installed after header before hpipe)?
With option 2, would it problematic that I have 3inch header, then 2.25 exhaust, then 2.5 inch muffler, then back to 2.25 pipes? would that like mess up exhaust flow/back pressure issues etc? Would the car sound much better than it does now, or I won't notice?

The car is a miami street cruiser, to be taken out with the spousal unit (as required on occasion). So i don't want it super loud all the time (cut outs for that), but would like it better sounding than currently is.
In this vid you can hear the exhaust, at 3min mark I open the cut outs
