Newb question here , I just purchased an Ultimate Racing Hi Flow cat for my 2011 RA. I still have the stock exhaust system. Will this bolt up to my stock cat back ,or not ? UR says it will when I contacted them ,but I'm kind of having my doubts as the stock exhaust has a dog leg in it . I want to keep the stock system for quietness.
Before I go through the trouble of grinding the rusty bolts off would he great to know if it actually fits.

 

I have a UR Test pipe with muffler and it was working fine on my stock exhaust system.

 

I have the UR HFC, and UR axle-back muffler, stock DP and stock MP. It's fine, but there's a decent amount of drone. When I buy the DP and MP to make it true turbo-back, I'm going to order the MP with the mini-muffler and resonator.

 

Thank you so much !Was not wanting fight the rusty bolts only to find it wouldn't fit in there . I've got the gst map and boost pill with coswirth filter but car runs extremely rich . Hopefully this helps it out some .

 

I recommend getting a protune, that'll help the most.
