M performance exhaust and mid pipe silencer

horsepower_and_hounds · 11-14-2017, 03:20 PM

I know the M Performance exhaust is technically not a "cat back" set up. Not sure why they don't do it that way and instead make you hack up the exhaust but does it delete the mid pipe silencer is it is like a cat back? I have been trying to find pics to verify

Yes, the silencer is gone on MPE, nothing but pipe.

Yes, it deletes the secondary cat. It's not a cat back though. You retain part of the pipe that connects to the primary cat, cut it, and then attach the MPE from there.

Also make sure you read up on the MPE before you buy. It drones and has vibration/rattle issues during cold start. Some people don't mind, others do.

yea i read that...and you have some wiring, the bluetooth can be finicky. But for the price and I already have carbon tips from my F82 I think it makes it a bargain. Are you guys using it and happy with it? Does it include the instructions for where to cut it and how to wire in the module?
My main concern is bluetooth interference with a JB4 and iOS app

I thought these were addressed with the new version? I thought they were kinda fixed. Are these still an issue?

Neither issue was fixed.

To my knowledge all they did on the European revision was add a button in the trunk to make it harder to activate track mode. And i saw some clamps added behind the tips that looked like they were designed to prevent shaking but the rattle isn't because of loose tips, it's because of where the exhaust is cut and attached. it isn't a good design because of it's length and where it attaches to the stock exhaust. you'll have rattle unless you wield the two ends together. The clamp isn't strong enough of a connection that far back and i guess backpressure during cold starts causes it to move around.

that being said it's a fantastic sounding exhaust, it just has a few quirks.

I just got the MPE about 3 weeks ago. No rattles yet. Looks like they changed the design of the main clamp.

The exhaust pipe from the MPE now slips OVER the exhaust pipe that's left on the car after cutting the stock exhaust off.

Dirtboy, how's the drone with MPE?

That is the same process as the F80/F82 MPE

I don't know. I'll have to ask my wife, she drives it more than I do. LMAO!

No, it's got the slight drone just before 3k but I don't think it's that bad. It must not be too bad or my wife would be complaining about it. Lol

I have it on my LCI and I love the exhaust. I haven't noticed any cold start rattling issues. I do have a bit of drone when on the highway cruising at about 70+ MPH but coming from an EVO X with full catback exhaust and an open dump downpipe its not bad at all. In my opinion the sound of the MPE is well worth the drone.

Friend of mine went with a VRSF catless DP and deleted the resonator/secondary cat, I?t sounds just like an aftermarket exhaust in terms of loudness and turbo spool noise.
