- So do alot of V8's with the wrong exhaust
- So are alot of 4 cyclinder cars 
- Have you ever messed with AEM, HP Tuners, Ls1 Edit. 
- I know alot of 7 owners that daily drive theirs with no problems at all. When you mod a car, reliabilitly seems to go down alittle anyways. 
- When you lose a piston or something, seems to cost alot to fix also.   
So I think they are no different then any other car.
