I've tried installing quite a few mufflers for the 3800SC swaps that we used to do. The Flowmaster has a good sound but is too big to have a full sized trunk and/or enough road clearance. The Flotech Afterburner fits fine but after using one on my install it proved far too noisy on the trip to Carlisle. I scrapped it and went to Spintech that uses a unique non-restrictive spin sound trap. While not completely quiet it had the lowest exhaust sound of any tested. Further sound reduction was achieved by exhaust wrapping the tail pipes.
IMO, running with a CAT will additionally help to achieve a low exhaust sound but in an engine swap configuration with an untouched trunk its a very tight fit

I've had a few locals ride in and drive my car and comment that my blower noise is more pronounced than theirs is and I was straight up with them, my exhaust system is just quieter than theirs therefore the supercharger is more pronounced. I do run a catalytic convertor and a Fiero style muffler, stock exhaust tips.
I have managed to package it all in without cutting the trunk and retaining the factory heat shielding plus a heat shield around the convertor, as you know it's an exercise of engineering. then again, I'm the idiot who actually installed a body control module to control my door locks and lighting, remote features such as remote decklid release and stuff:P[This message has been edited by jelly2m8 (edited 09-03-2023).]

There's a reason SS Borla mufflers were expensive.

I am starting to think the idea from Jelly2m8 of custom making one may not be a bad one.
So this is basically factory 2.8 muffler "size", but the tubing internally and externally is larger? I have a fab shop that can help me with this.[This message has been edited by cam-a-lot (edited 09-05-2023).]

If you add up all the $$$ to build custom;, calling SpinTech might be more cost effective and with an easy bolt on. They will build to spec and their mufflers are heavy duty.------------------
