I just picked up a used XLR8 resonated exhaust for my car but the guy had the flange cut off where it connects to the JPipe. I called excelerate performance and all the guy would tell me is that any exhaust shop should be able to help me out. He couldn’t tell me the dimensions or anything and he said they don’t sell just parts. Does anyone know know where I could get one or specifics? I also just purchased the RV6 V3 HFPC and V3 endless J pipe. I really want to put this together the correct way and not weld the 2 together. There are no close exhaust shops to me but I have people at work who could weld the 304 stainless and then I could just bolt it up. Thanks for any help.

Check out RV6's website, there may be something on his hardware page that you can use as a template to have something made?

Ooh that's tough.

You may have to have a flange made based on measurements from the post-HF-3rd-cat flange on the Endless V3.

Worst case, sell the cut-up Xcelerate catback and get a catback with flange.

Also I just ordered that same combo for triple high flow cats and am now seeking used catback...

 

I only paid $300 for the catback. I’m heading to an exhaust shop near me in a bit to see what they can do. Worst case I can have it all welded together. I haven’t been under the car to check but not sure it would even need to be removed anyway for maintenance purposes.
