Took a about a quarter of the time to adjust, rubbing was a no issue but one of the tips had a tighter opening, this made making it match the other was a pain the ass.Hey Carlos... Hopefully you have no exhaust rub, went through three design with MBRP, a lot of on/off to try and make it work but was never successful. Remove and went with Magnaflow system and it fit like a glove first time... Good luck...
