So I have been looking at getting a set of resonated test pipes for my g but had a question that maybe someone can help answer.

Why is it that only the berks test pipes have brackets to reuse the stock cat brace and no other companies use this bracket? I am worried that the resonated test pipes will cause extra vibration and/or crack prematurely without the oem cat bracket in place. I thought about getting the FI resonated test pipes and welding brackets on them myself. Any thoughts or guidance is appreciated.

 

which test pipes don't have brackets?

 

All of them except the Berks AFAIK, and FI HFCs don't have them either. So far my OBX RTPs have been fine, I guess time will tell................

 

I have read a few posts of people saying that it adds vibration to the car and that installing the bracket fixes it

 

i am not sure about test pipes. but i had HFC on my old g35. i think the OEM cats use the bracket because of the weight of them. i am not sure the exact weight, but the OEM cats weigh considerably more than my HFC. but i never had any issues with vibration. i ran them for about 70k miles.

 

Hey blnewt do you experience any vibration with your obx pipes?
