I run a single 3" Spintech Super Stock-Race Quiet on my truck with stock cats and y-pipe. I cant wait to hear it after some Dynatechs!

My buddy is running dual pro shoot outs and his sounds pretty mean behind stock cats.

here is a link to a couple videos

I don't know how they would sound on a III Gen but I used to have an Edelbrock RPM Series on my 85 Trans Am. That thing sounded mean Everyone thought I had a beast of an engine but it was only the stock 160hp/245tq 305

 

i have true dual 1 chamber flowmaster and everyone thats ever heard my truck loves it
