I'm going to cut and weld one in. My old 2.5" system had one as well.I’m going to need new exhaust in the near future, 3” looks like the way to go. Are you going to do an H-pipe?

Is it possible to take a pic of a 2.5" vs. 3" pipe, end section for comparison?Started replacing my 2.5" exhaust with 3". Got a kit from Jegs and 2 Ultra Flow mufflers. Had to make the driver side shorter to get it through the trans cross brace. I'll finish fitting it tomorrow and get it welded up including a crossover pipe and o2 bung.

It's rather remarkable, more than most folks think it is....
Oh, and be prepared for some increased interior temperatures with the 3"!
Thanks! Yep, that's my point - that little ol' half inch in diameter gives like 50% more flow/volume,View attachment 1473861
You ask and you shall receive.
So area of a 3" circle is 7.07 sq/in. Area of a 2.5" circle is 4.91 sq/in. Volume of a 3" tube 8' long is 678.58 sq/in. Volume of a 2.5" tube 8' is 471.24 sq/in.
Finished it up today. I think I have a piece touching the trans crossmember. Of course it was fine until I welded it up. I'll deal with it tomorrow.
Dynomax Ultra Flo. No baffles just a perforated inner tube.I likey. What mufflers are those?
Prior to welding...I'm going to cut and weld one in. My old 2.5" system had one as well.
Always liked Dynomax stuff. I assume the fiberglass will burn out at some point?Dynomax Ultra Flo. No baffles just a perforated inner tube.
Funny story. 2015ish I was working on my 62 Belvedere so I ordered the complete 2.5" kit from Jegs, including the mufflers. The car sounded great despite a drone from 2000 to 2200 rpms.I also have the jegs 3" complete set. I love the sound !
