Cobb AP with aftermarket exhaust

x46359 · 05-15-2013, 07:26 PM

Quick question on the Cobb AP for the N54. I currently have an aftermarket exhaust (aftermarket mid pipe with no cats and aftermarket axle back) with everything else stock. Will I be ok to run the Cobb AP stage 1 or do I need to put my stock mid pipes back on? Thanks.

You're good to go.

Thanks...I'd much prefer to run it with the catless aftermarket exhaust

Anyone else have any issues with this setup?

Stage one is for cars with cats or no cats.
Stage two requires no cats.

There is a chart on their website that describes this.

Thanks guys for the quick feedback. I just wanted to use the off the shelf maps and the cobb site specifically mentioned the stage 1 is ok with catback exhausts so I was a little bit concerned.

I ran COBB with BMW performance exhaust no issues... don't think the PE dose anything bar sound bloody great and give me a little more throttle response. went very well together.

The Cobb AP, when referring to exhaust, is only needed when running Cat-less DP's. Your MP's and AB plays no impact on anything...

What I was about to ask ("Can I run stage 2+ FBO, except having aftermarket midpipes?"). Thanks for clearing that up 010111100010101010100101
