[1and1]

Over the 35 some odd years I've been wrenching on thing (cars, bikes, anything that held still long enough really....) I've seen almost every auto manufacturer have these dents in the OE exhaust parts. Every time I've seen a supposedly official answer/reason for it the wording has basically always come down to a clearance issue- wanting more basically.

They test to some pretty odd standards or situations that most owners would never conceive of putting their car through. At some point the 135 exhaust actually managed to touch the lower control arm or whatever. Now, there's a dent....
