My truck has been straight piped for a while and I love it! It is just the stock 3.5in painted flat black. oke: Take a look at the video at http://www.youtube.com/watch?v=K0_IfgF8F2M. I think the 3.5 sounds the best because at high rpms and high acceleration the exhaust barks! I think it has to do with the exhaust pressure. The bigger exhuast bellows, but I think any size straight pipe sounds good!
