I agree with Jeff and PercentSevenC. 2" OD mild steel 1/8" thick wall is the way to go. The thicker steel really reduces noise.
And the muffler packing material must be stainless steel wool, especially for any muffler close to the engine (before the rear axel) otherwise it'll self-destruct.
My neighbor just complained yesterday about my REPU being too loud so you guessed it - gotta redo the center section of my exhaust which is thinner aluminized steel and magnaflow fiberglass & stainless packing. that magnaflow has gotten gradually louder to the point it annoys me. oh well it's just time and $$$.

Well I bought this exhaust for $200 locally, I didn't expect much out of it, I just needed an exhaust to pass safety inspection.
Once winter is over, and the car is back on the road, Ill fork out the money for a good system, with my RB header.

Tuned exhausts
Hey, I had an idea.
I've been watching the threads and folks seem to have a variety of exhaust configurations. Some have RB headers, pacesetters, with/without pre-silencers, different mufflers, and even home made configurations.
I thought it would be cool if folks could post a description of their exhaust configuration and attach an audio file of what it sounds like.
I think it would provide a good way to compare sounds so others can replicate the exhaust of their choice.
Comments?
