hi, I am in the middle of stripping and rebuilding my 1987 gt fiero, and on the list of " to do's " is to port the exhaust manifolds and y pipe. I think I am going to buy rodney's aftermarket stainless catlytic convertor ( altough going to check with my local garage that test emmisions as cat's were made legal here in 1988 i think so i may just delete the cat and have just the muffler) my question is which muffler to go with, and i prefer if it was made out of stainless steel, can anyone point out any good makes to go with? does anyone recommend spintech's muffler's?
thank you for any help jon

I tried a few different mufflers on my V6, before settling on my current setup (which is a modified Ocelot muffler). First, I tried a cherry bomb... sounded ragged and raspy... didn't like it. Then I tried a Supertrapp... sounded like a big exhaust leak... sold it. Then I tried a Hedman glass-pack... was buzzy in the upper RPM range... eventually tossed it.
I've also ridden in Fieros that have Flowmaster mufflers. They sound great at idle, and during moderate-to-hard acceleration, but tend to drone at cruising speeds. I personally find that annoying.
This sound is with a Thrush Welded muffler, a cheaper version of a 2 chamber Flowmaster, wouln't change it for anything! Video doesn't make justice.The kids around the neighbohood have named me "Euromuscle" because of the sound, they love it. http://www.youtube.com/watch?v=uRf0UgHKJ9E

I have a 2.8 5spd. w/ spintech muffler and a short glass pack in place of the cat. The spintech sounded nice alone, but the glass pack takes that little edge off ( re: brassy sound) . It sounds deep and mellow at idle and doesn't change to ricey and loud at higher rpm.
