So I've decided since my warranty's 3rd party has told me I can make changes to my car such as a aftermarket exhausts. I just want to know how I can make my car run smoother, faster, and most important have a powerful sound like when i'm accelerating.

Things I want to get done:

1. Tinted windows.
2. Replace stock exhaust system with a good equality aftermarket exhaust.

tips and suggestions are most appreciated.

 

a couple years back when i got my tint the only choise was metallic, or ceramic. Ceramic reduced more UV rays i think, and is just higher quality. but you pay way more for ceramic. i went with metallic

Im currently shopping for an exhaust. see high performance exhaust

Brands that I know of: Stasis, APR, Milltek, AWE. I'm most interested in AWE right now, for the reason see my thread. Also, Stasis is closely related to Audi so they would be the least likely to have issues as far as warranty goes. That's why you pay more, because i believe they match the factory warranty. at least that's what I was told when i got my Stasis tune, "everything is the same".
