ETS's testpipe design has a bend in it and they claim it is because the straight test pipes will rub against the driveshaft, I was wondering if anyone has had that problem with other brand test pipes

 

I have heard a couple people complain that their "straight" test pipe was rubbing against that bolt and causing some serious vibrations but most people run the straight test pipe and have no issues. All AMS test pipes are straight. I personally went with a curved test pipe because I wanted to stick with the "oem" style(the stock cat also has that bend), and wanted to make sure there was going to be no issues. I bought an ark performance catback and testpipe. Got a good deal and they are top notch products.

 

I have a megan test pipe and it was hitting that bolt. But I cut the bolt off. Lol u don't need it it just holds the sheld on and there are 2 other bolts that hold it on.
