Is there a guarantee of any kind that your sport cat will not throw CEL's? I initially was thinking of going catless but since i'm not tuning i'd prefer this route, so long as it will never throw a code.

I've had my Sport Cat on my M235i for over 15xxx HARD miles and have yet to throw a CEL. We can promise you that our Sport Cat will not trigger a CEL.

I'm going to send you a PM now as well!

Yes whether you have Dinan tune or not will not matter in terms of CEL ... We have had the best luck with the Fabspeed catted downpipe

Have you guys seen a Sport Cat on a Dinan Tuned car? Would you consider it a good idea to add one to my Stage III package?

I do not think we've had one in the shop but I am sure there are plenty of guys running our Sport Cat with all sorts of Dinan upgrades. Anytime you can reduce the cell count in a downpipe (especially turbo cars) would be a good idea. Not only do you get a nice bump in power but also some sound as well!

A sport cat DP coupled with your heat exchanger set-up is going to be beastly.

Most definitely! Probably one of the best parts of adding our Sport Cat.
