To be honest, I wanted to get the Greddy SE single, then someone told me to get the dual cause a single looks funky on an ap2 bumper. I found it more cost effective to get the dual instead of the single, ap1 bumper(painting it LBP), and getting a single exhaust cap so it looks right. 100% Satisfied with my choice. Always get tons of compliments at every track day. The dual sounds like the motor is bigger(v6 esque), which makes people ponder...can't wait to get my HT(mugen) and take off the H emblems to cause even more confusion.
