Just curious what you're running to require such a massive exhaust?
The ricer 'fart can' noise is because people put an exhaust on that has not alot of sound resonating qualitys (Simply adding a cannon also has this effect)
So, downsize your exhaust, put a Resonator in, or live with the noise.
Could also be your heat shielding above your muffler/exhaust piping.. With alot of noise they will vibrate and piss you off.
