Well I came across a great deal on a barely used Stillen Cat Back system and bought it despite many saying its too loud. I didn't want loud either, I just wanted the same sound as stock but a lil louder would be perfect. I also picked up a set of High Flow cats from Crawford. Overall, I am impressed and do not think the exhaust is anywhere near as loud as everyone thinks. It is fairly quiet at idle and driving normally, throatier n deeper then stock but still sounds similar to stock note wise. Once you hit 3-4K is lets out a nice groul! I am very pleased and just figured I would post up that the Stillen isn't loud as everyone makes it out to be! Went to the track teh day after install and received numerous compliments on the sound!

BTW - Can anyone else with the STillen exhaust confirm that the tips are recessed a bit. I was hoping they would stick out more to where the stock tips ended.

 

drew look at this thread... Stillen is right at the top, but the pic posted there doesn't look like yours really

 

I wonder if there is a difference b/w single wall and dual walled tip styles? There shouldn't be but who knows!
