Are racing pipe upgrades worth the money? I have heard the stock pipe that comes with the avalanche called a "tuned pipe" but I really doubt it's that great compared to the expensive ones. The SH .28 really screams as is but I heard that putting a real good pipe on it would make a big noticeable difference. Anyone know if this is true? And if it is true I'm up for suggestions on a good brand or model.

pipes can make a great deal of difference, the stock pipe on avalanche is pretty good, if you want a good exhaust setup get the jp3 pipe.

Different style pipes give types of performance. A long narrow pipe will give you RPM performance a short fat pipe will give you Torque performance. Basically the RPM pipe will use the high end RPMs of the engine and produce power there, the Torque pipe will use the end(take off) rpms of the engine to produce power in the low range of the engines RPM. SO it depends on where youw ant to get your power from. THe stock exhaust is a great midrange exhaust that uses pretty much the full range of the engines RPMs
