I just bought a 2002 Z28(all stock) and was thinking about putting just a muffler upgrade on. Does anyone have any sugestions? I've heard a lot of good things about the Flowmaster 80 Series.

 

All are 3" inlet, and dual 2.5" outlets.

Loud Flowmaster like sound, flows really good, heavy gauge steel case (I've got this one, except with 3" outlets#344 SC). IMO,Sounds great!
Magnaflow, pt# 12267
Stainless Steel, Great flow, quiet until you get your foot into it!

Realy good flowing, louder than the magnaflow, very popular!

PM sent.

 

And if you want to just dump the exhaust before the axles get a Magnaflow (pt# 14419, 3" in/out, 14" body length, $73) 4" diameter muffler with a turn down.
