Hey guys, it’s getting close to smog time for me and I currently have a set of ARH long tube headers with cat delete on my 2011 C63. Great condition and not many miles on them. I’m looking to trade for a set of long tube headers WITH high flow cats - California smog legal. Ideally I’d like to trade for another set of ARH, but I’ll consider other options. I’m located in San Diego.

These damn CA smog regulations are a pain in the ***...

PS - I’ve reached out to ARH to see if I can just buy their standalone high flow cats but they don’t sell it separate from the kit.

Could you not just weld in a set from mbh, flowmaster or any other kinda out there?? There has to be a set that will work for your application

Just weld high flow cats in. ARH/MBH don’t use anything special for theirs.
