I just wish they would keep those things off the road, They are worse than the ricers. Alot of diesel rigs running around here with those fart pipes hanging off the back. Noisy than all get out. I was in one of those add-on stores the other day, buying SS lug nuts for my K5 (I hate rust!), the guy in front of me asked if they made a 8" exhaust for his new cummins. "Yeah, I got a 5 now, I want an 8". Idiot.
