1989 Iroc Exhaust

you guys are really great on this site.....my next question is...I would like to make the exhaust sound a little bit meaner....but keep in mind where I live I have one emmissions test left next year before it will not require this testing anymore......running 305tbi and exhaust currently is still factory

thanx again

search on e-bay or summitracing.com for mufflers for your car. Just doing the muffler will give you a more aggressive sound and flow a little bit better and will not hurt your emissions. Why is it that you only have it for one more year and then no more???

any suggestions on which brand or type of muffler to buy....where i live an emmisions test is good for 2yrs....i will have to do a test in 2006 and when the car turns 20yrs old in 2009 it will not require testing anymore

thanx again

Borla, expensive but you'll love it.

No screw borla, they are over priced. You could do some searches on the web for sound clips of certain mufflers on your car, I know they have a site like that for LT1's and stuff so maybe you could find one for yours.
