Hi everyone, I am planning on putting a quad exhaust on my M tech II rear bumper and currently have headers installed with stock section except no muffler... But would like to reduce drone,rasp sound ...
What would ya recommend? Glasspack in section 1 of the pipe before the last resonator?
A x pipe before the resonator?
i like the sound is just that I get annoyed every now and then about the drone while cruising.
