salomaan 0 Report post Posted May 29, 2016 Yo wassup ya. I have a stock 99 Lexus Gs300 and I want it to sound more aggressive and louder. Can I get some tips on how to make it louder and/or any links for any purchases I can make to make my Gs300 louder? For example maybe exhaust/straight pipe or what not?
