I had purchased and put on the steeda side exhaust approx. year and a half ago, took it off like the 3 mos later, terrible. Never fit right, sounded weak. I ended up having a muffler shop make mine (no muffler actually) and now it fits perfect and sounds brutal. Any body wants steeda side exhaust mufflers let me know you can have them.
My suggestion to you is to get the mufflers and tips you want and have muffler shop build the rest of your pipes so it fits you car perfectly, an out of the box system is very difficult to get perfect fitment, every car is a little different, production tolerances. It only cost me like $120 for the shop to install it with the pipes they built.
