Most of the driving I do with my Swift is my backyard. But the pipe that comes with the RTR Swift is like a "straight through" and it's very noisy, and my neighbors are complaining. What pipe can i put that works but is quieter. I've seen some that have like a separate"cherry bomb" at the end, I think that should work. Can anyone recommend me a good quiet pipe, and I don't care if it reduces hp a little bit, the more restrincted the pipe is the more low end power, and that works for me. Thanks. (the engine is a .21)
