I havent heard the SLP Exhaust yet but I do like the sound of the Zoomers. I am gonna have to wait a while before I do any mods on my car as Regestration and Window Tint just wiped out my current funds. I am going to have a hard time deciding on Exhaust also....Zoomers, Borla, Magnaflow [&:] Need to hear them all in person and weigh the $$$ first.
