Dinan xpipe vs OEM

Teerump · 03-21-2020, 09:31 AM

I currently have a Dinan catless xpipe and rear section, wanting to get something with cats to reduce the smell. Would going with an OEM xpipe, removing primary cats and adding test pipes, keeping secondary cats accomplish what I'm looking for without losing much power?

Not really. The secondary cats are not overly effective. I used to run test pipes. Now I have an x-pipe with HFCs. Much better. Still smells a little, but it is ok.

What xpipe you running?

Sell it and buy an X pipe with cats preferably the bimmerworld one as it's the best

I ran TMS test pipes with OEM Midpipe and now have the Dinan midpipe. I can say from
experience that the smell is way more present now with the Dinan.
