Racing Beat. If you do a setup like the one "definitely recommended" above, you will piss off all your neighbors and go deaf in the process. I don't even want to imagine the drone on the highway.
Ok first nice quote
and second im looking for a lower throaty kind of a sound. Ive heard that pipes 2,1/2" to 3" diamiter are better for HP but what's do you look for when looking for low sound?
and if by throaty u mean like an srt4 i got water in my exhaust pipes type sound i hope ur kidding.
lol that wasnt quite what i was talking about...i meant like a STI with the STI muffler, amazing sound
People had problem with the HKS. I love my Thermal catback.
