i put a slp loudmouth exhaust on my exs car a few years back. it was a 3.4 grand am gt. i personally thought it sounded nice at idle but obnoxious at any other rpm. real loud inside the car, and i like having loud cars but i think if its going to be loud it needs to be able to back it up.

 

I love both your Dynomax and SLP exhaust system. And as of right now I can't decide which one I'd like to get more. Just wondering which one you like better? Also, is the SLP system a straight pipe design whereas the Dynomax isn't?
