I've narrowed down my muffler choices to Borla, seems like a great quality muffler . Now I got another problem, idk what type of Borla muffler to get, xr1,xs, or xl? supposedly xs and xl are the same?
after i make that decision, I'm also trying to see what would overall benefit me the most, true dual, DI/DO SI/DO, i just want the best bang for my buck, I'd greatly appreciate you're opinion, THANKS!
