Well my guy sounded funny anyhow, the blown out CAT, when it went damaged the resonator and muffler. My guy had a strange aftermarket exhaust system that looked and performed like it came out of the JC Whitney catalog. Bought a stock from Toyota and all is well. So when does it sound like it is farting? Wonders if I can rig up can fart for the general public's "pleasure". LMAO :p

The fart (like people farts) becomes evident when there's a greater volume of air to be expelled (higher RPM, higher throttle in the case of an engine; Mexican food in the case of many humans and my dogs). Personally, I think it's awful and in many cases it may be costing you power just like removing the intake resonator.
