Active Autowerkes Midpipe

[C_Treadwell]

Selling a slightly used Active Autowerke mid-pipe for F8X (M3/M4). Drove it for 2 months and replaced it with the new Dinan mid-pipe. Resonator and 1-cat delete. PM me if you're interested.

Any vid? Stock muffler? More importantly, do you like it or would go a different route?

Vrsf dps, bms intake, stock exhaust jb4:

Vrsf Dps, aa midpipe, stock exhaust, bms intake, jb4:

Video will obviously not do it complete justice, but gives you a decent idea of sound.

Definitely like it, but I will warn you it is loud as hell especially catless dps.

OP do you also have the Dinan rear exhaust paired with the Dinan mid pipe? Would like to hear your review and possible videos if you have any.

Thanks

I really love the Dinan muffler. Adding the Dinan midpipe didn't make much of a difference because they didn't remove the cats. The AA is much more aggressive, throaty, and pops, but also had a tendency to vibrate the cabin at idle. We likely could have fixed it by modifying the shape of the pipe where it made contact with the cross bar, but I decided to stick with the Dinan. Mainly to maintain my all Dinan build and warranty, but the vibration played into it.

Here's a video that includes a cold start up, rev, and drive by clip:

No video yet, but I'll record one. Honestly sounds about the same as just the muffler section and Dinan's video is pretty accurate:

It sounds good, there's no vibration or drone.

My man! Exactly what I was looking for. Thanks!

I don't have any vibration issues with my AA exhaust.

[JDE92M3]

Zero complaints with AA midpipe, actually my only small gripe about the midpipe was the interior noise was still quiet. But outside the car was a different story lol.

If I'm not mistaken, the AA midpipe was paired with a Dinan axleback muffler. I'm assuming that combination may have been the source of the undesirable noise/vibration. Many other reports tend to talk about the subduing effect of the AA axleback when used with the midpipe.

Hope that's not the case since that's the exact setup I'm doing.

I've seen about 3 F80s with the AA Midpipe vibrate against that middle brace on cold start, but not on the F82 for some reason (Or i haven't seen yet at least). The fix for all the cars has been to unbolt the mid pipe, push it up, and retighten. Fixed the issue on every car, for what it's worth. I have a little more clearance on my F82 w/ AA mid pipe than my brother's F80.

Good to know

[gimmethemuumuu]

Indeed. Very good to know. Mine's an F80. I'm glad to know there's a fix if I were to experience the indicated vibration. Perhaps the OP just didn't want to mess around with it anymore. And, as indicated, perhaps there's some value to having an all-Dinan setup

[SflBimmer8484]

I have an f80 and no issues since install. I recommend putting a wood block between the pipe and the brace then tighten so when it settles it sits in the correct spot.

This reminds me of the old E46 days, fitting any aftermarket exhaust section 2 to help with rasp on those was always a problem, never fit 100% perfect. Deja vu all over
