Catless Downpipe selection questions i cant find answers to
Meisterschaft sells a 76mm and a 90mm Downpipe.. the 90mm has a "reservoir tank" ..
- what is a reservoir tank on a DP? - should i get 76mm or 90mm and which works with OEM heatshield and should i get powedercoated or wrap with that volcanic fabric wrap ? |

Call their customer service. I've talked with them multiple times they're very friendly and knowledgeable.

If you are not pushing over 900hp don’t bother with a DP. Stinks up the car and does nothing.

I don't think it's too terrible..personal preference imo. It makes the car sound amazing even with stock exhaust.

and then after a few weeks I was going to get a BPM stage1 to get rid of the check engine light from the 76mm meisterschaft downpipes which I found out the 76mm DPs are the direct OEM replacement to put in OEM exhaust piping versus the full meisterschaft exhaust which calls for the 90mm/3.5". but stage 1 to get a little bit more power but maybe do bpm stage 2 since going catless.. but after speaking to BPM just a minute ago via email and they said the only downpipes that fit perfect are the OEM ones and to gut those but I think I'll just go stage one and leave the factory down pipes what do you guys think honestly?? I just want a little bit more power I want 2nd gear to be angry like first gear but im not a mad man. i dont want to upgrade clutch pack. I had a dinan stage 2 obd flash on an n63 motor aka f10 550i which supposedly gave me 90 hp and if the bpm stagd 1 is just equal to that ill be happy (i'm hoping someone will chime in and say that stage 1 on m5 is way better) but i'll get 305 michelin 4s after tune as i have 295's now and ill need a lil more grip. |

I have bpm stage 2 with vsrf downpipe.
Sounds crazy abd its fast fast...... I got it last Oct 2018. So far no issue no check engine light nor error message. Dp does create bad smell but i love the way sound. Plus only gets loud when you throttle. |

LOL. Tell that to the people spending $8k+ for a Akrapovic cat back + install with minimal power gains. $1200 for DP is nothing in comparison... and will actually net some gains.

$8k for some stainless steel! That is some incredible profit margin. Surpasses Apple's ridiculous margins.
