Looking for OEM downpipes

aric3320 · 01-14-2018, 11:12 AM

I bought a 2010 135i with catless downpipes. I am looking for a set of OEM downpipes so I can pass an inspection in NY. The cat delete mod seems pretty popular I thought it would be easier to find a set. Having trouble. I live in upstate NY, not too many of these cars around.

Also wondering if the 335 cats would fit on a 135

Thanks!

335i cats fit 135i. and look to get a downpipe fix. its a 80$ part that is an O2 simulator so it will show your catalyst monitor as complete.

This is why I don't want to get cat-less down pipes, however which simulator works? I forgot...
