Since my car ended up needing the slip on version. I wasn't able use them. I did just install and different set of Catless downpipes (slip on) and they gave the car a much deeper and aggressive tone but it didn't add drone. I think that depends a lot on your Catback setup. On stock mufflers i dont think there is any drone but If you already have drone i assume it would get amplified.
Performance wise its been my favorite modification.. The turbos spool up way faster ( You can hear this now) and the car feels much faster.. Last edited by MpJaj; 03-09-2017 at 06:34 PM.. |

Yes it may trigger the CEL. These downpipes have the extended L valve on the 2nd 02 sensor which may reduce the chance of getting a CEL but it will most likely trigger it eventually. I have the JB4 which eliminates this problem and just sold my BMW CAN tool which also eliminates it.

You will want to confirm but its pretty simple to check because this area exposed from the bottom. Just follow the exhaust to the point where it starts to angle up towards the engine. Toward the bottom the downpipes will either slip into the bottom portion of the exhaust or be clamped on with a couple bolts. If yours are bolted on then these are the ones you need. |

Anything before 04/11 Prod date is Flanged style
04/11 and later is slip fit. If you have 04/11 Prod date you may want to verify which you have. Somewhere in 04/11 BMW stopped using the flange style. I also have 04/11 Prod date and my N63 has slip fit. |

Or sorry I have the slip style. Not flanged or bolted if that is what you're referring to as the flanged model.

No issues that I am aware of.... I sometimes run my car on Map 0 (JB4 Bypass/Stock) and the gains are still substantial. The manufacturer claims 30-40 rwhp on stock setup, I haven't dynoed my car but those numbers feel accurate to me. Even more noticeable is the increased throttle response and deeper exhaust tone. |
