Help passing emissions with a catless N55

That red N55 135i · 09-12-2019, 11:30 PM

I just recently purchased an n55 135i that came with an AR Design catless downpipe. I've tried to see if there is a DP fix for this brand, but cannot find any information. Does anyone know of a possible DP Fix (like the VRSF) that might work on the AR one? If not does anyone else have an AR design catless downpipe and have to pass emissions? I also have a Jb4 tune on the car and it's been on map 0 and should be okay with some sort of DP Fix. Any advise is greatly appreciated. I'm in Arizona so to my knowledge I can pass emissions with 1 "not ready" on my emissions testing.

Do a google search for Area 74 N55 DP Fix.

Might also be easier to find someone else that would let you borrow their catted DP for a little while.

Goodluck.
