What options for high flow cat?
I know there are numerous threads out there discussing this but I am getting overwhelmed with all the info. Can someone tell me what the different high flow cats are available for the F36 N55? Also, The cat is in the downpipe correct? BMW's are new to me so I am still learning. Thanks for any help.

The cat is in the downpipe. Check out Fabspeed. They have a high flow that will not throw a CEL. It's $1400 though. If you have a tune that can clear a CEL, you have more options. ER, Wagner, etc.

If you are looking for a guaranteed CEL free operation, I believe only Wagner and Fabspeed offer that guarantee. If you are just looking to clean up sound and emissions then you can save a few bucks and go with VRSF. |

The HJS Euro 6 300 cell DP is also CEL free and a few bucks more than the Fabspeed DP plus it looks close to OEM and is built to OEM quality.

From what I've learned on these forums is that for those of us that live in a state that has strict emissions (Massachusetts) the only down pipe that will definitely pass state emissions testing is the Fabspeed DP. I wish that wasn't so because their DP is about twice the cost of others...

If you are using a JB4 or keeping the car stock, get Fabspeed. Fabspeed offers a no CEL guarantee. We got both in stock

Mike, will the Wagner catted DP pass state inspections? I'm more concerned driving around with a rejection sticker on my windshield that attracts the attention of the police than the CEL light on. Thanks. |

Im not an expert on emission laws for different states, my guess would be no it will not pass
