Is this downpipe compatible with MHD tuning? I've read some other "no cell" downpipes are not tuning compatible.

There is no downpipe that would not allow tuning the car after.

Yes, I ran it a little while with MHD. The real benefit is it won’t throw a CEL on a locked DME.

A downpipe has nothing to do with a tune. Whoever wrote what you read needs more grey matter.
Probably the same people saying 8.8 and 10.9 on the cam bolt head meant you have the old or new oil pump..

Could you please link to where you saw this, so that we can shut it down from the source? So that idiot doesn't keep spreading misinformation.

Oh you weren't here for the drama. A90 shop and armytrix had a falling out and so a90shop started making shit up about armytrix dp's not working. I'm personally at 23k miles with a mixture of locked DME and MHD tune (witb cat monitoring ON) with no CEL.

Can you link us to the kenji comment?
Thanks for the clarification. I was never referring to a specific Kenji downpipe comment. My question was about cat simulation in general.
