No,I never had one.
With exhaust you get what you pay for.
I have a Magnaflow X pipe and the quality of the stainless steel is excellent. :thumbsup:
Also I would get a Magnaflow X pipe again.
I have a UPR offroad X, ive had it for a year and a half now and i dont have one bad thing to say about it. The design is great and the pipes are still rust free.
