I am a big fan of stock exhaust with catless downpipes. How I have ran our N54 and now the S55.

I recently change into an armytrix catless downpipe today in my 328i and it didn't trigger any CEL.. It has a fake cat inside the bottom O2 censor so the ecu detect a good cat in the downpipe..

I am selling an Evolution Raceworks Catless Downpipe that does NOT cause a CEL code. I have used it for less than a year. I am also selling the matching Chargepipe.

Let me know... Thanks!

I would not advertise it this way, it could get you in a lot of trouble if buyer got a light and decided to ask for his money back + labor cost and shipping.

All catless downpipes will cause a light unless you have a tune. The light is caused by the cats not being there.

Mike,

I had a JB4 tune, yes... And I'm also selling that tune which could be purchased along with this DP of the bigger chose to.

This two combined = better performance and NO CEL Code

Is it advertised this way from armytrix? That it won't give you a CEL.

Would the BMS can flap module work to clear the CEL in this case?

Any updates? Looks like it's been 9 months since you installed these. Can you comments about sound. I'm thinking of going catted dp with stock exhaust on my 328i.

Hey Mike, or anyone that would know. So is Evolution Raceworks the only manufacturer out there that makes a catted downpipe for the n26 engine??? I'm with some of the other guys. I would rather stay legal and not deal with a check engine light.

AR used to make these DP but they are out of business
Wagner do N20 only

ER is the only company i am aware of that makes these DP
