Try running valves open first. Might change your mind and save some dough. Then paint the muffler black.

Another proud AA owner here. I'll take hand made in the USA over some janky Chinese knock off any day of the week, and twice on Sunday.

To the dude/s asking about the smell and passing emissions; I can't speak for your chances with just a midpipe, but my setup with downpipes, AA mid, and MPE... uh yeah... good luck with that lol. That combo stinks to high heaven, but lawdy if it don't sound good!

My 2020 comes with black gloss tip mufflers. I think its part of the ZCP package. From what I've been reading, having just AA midpipes is not nearly loud enough so I'm looking for axle back suggestions. Seems like Remus is a popular choice.

just slap any axle back on whatever u find cheap used around you. your in used parts la la land.

i got remus aa valve controller tune sounds sick. im sure it would sound sick with almost any axleback. the remus does fit nicely tho with the adapters.

def go AA midpipe; why save like 2-300 bucks for a knockoff

PSA(not directly at you op) no matter how much make up you put on it; the exhaust note won't lose its character. it really isn't that bad; i think exceptions are too high after a NA v8.

ftype r; c63s all sound good; but not OMG.

you would want a e60 or a something v10 and up for that symphony.

tl;dr get whatevers cheapest in the classifieds around you

I can see that. But running valves open bypasses the muffler and is a bit louder with more character. Open the valves and pull fuses 146 & 147 in the trunk to try it out. It's free.

That said, sometimes I want more sound, but the car can still be fairly loud. I'd go to a high flow catted DP next though (not willing to run catless in my old age).

In our flash software we have the option to have sport and sport+ Valves 100% open. You can also do it manually but it wont close in comfort/eco. Put the car in sport plus give it a small rev then unlpug the sensor to the valve. Be sure they are open 100% visually before you unplug it.

If you want it louder you may want to consider our Full signature exhaust system, installing downpipes or another axle back of your choice.

+1 - Be sure and do this. It's a cheap and quick mod that makes a bigger difference than I ever could have imagined.

Big thanks to all that have supported us over the years!

How come my car got so much slower with the AA mid-pipe?

I also have a VRSF DP and BM3 tune. Tried both Stage 1 and Stage 2 but it's just much less powerful with the mid-pipe. It sounds great though. Am I missing something?

One more question for you AA users - did you replace the flanged nuts when connecting the single midpipe to the DPs? Looking at Realoem, they show the gaskets/seals in a grouping that includes the flanged nuts and there's a notation about "required for repairs". Speaking of the gaskets (or "seals") as they're called on Realoem, where did you purchase those? I don't think they're included in the AA midpipe kit, are they?

OK- thanks. I'm down for the gaskets for sure. Did you replace the flange nuts too? Mine aren't very rusty from what I can see.

Something must have gone wrong during the install because there's no way you should have lost any power, let alone enough to feel much slower. Do you have actual before and after numbers or is it based on how it feels alone?

I didn't bother replacing the nuts myself but I also live in California where rust and corrosion really isn't an issue so mine weren't rusty at all. It might be worth getting new ones just so you don't get stuck with the job half done in case yours do get damaged.

It is clearly a lot slower. Especially north of 80 mph. Just much less torque. It was installed by a pro BMW mechanic and I was supervising it. I don't think there is that many things that can be done wrong. It's a pretty straight forward install. But then again, the power loss must be caused by something.

Weird. Considering the simplicity of what it is I'd guess it's coincidental that you lost power at that time. The only way I could think of at all that the midpipe itself could cause a power loss would be if somehow yours has a big obstruction in it which seems really unlikely... I've been to track days before and after installing mine and up to 150 mph there's certainly no loss of power at all, just much better/more sound.

Hmmm maybe there is a leak somewhere? I will look at it tomorrow.

The gaskets would be recommended to replace because they're designed to be one time use and get crushed in the process of creating a leak-proof seal between the DP and mid pipe. You could chance re-using them, but for the peace of mind I just did it to save myself from having to unbolt everything and replacing the gaskets in the event they leaked if I chose not to replace them (plus they are relatively cheap). The flange nuts I bought too just in case, however they were unnecessary and I ended up reusing the old bolts. If your bolts aren't rusted and look fine, I would just re-use them.

I ordered the gaskets, figured there was no way they'd be re-usable - but I held off on the flange nuts. It's all supposed to arrive this week, so by next Sunday, I should have it installed and can report on the results.

...and it arrived yesterday. Now all I have to do is either install it with some help from friends or take it to my favorite Indy shop. I just have to wait for the gaskets to arrive in the next day or so. Thanks to Mike for a quick turn-around on the transaction!

Update - my favorite Indy shop will do the install for under $100, so I'll get that done either Thursday or Friday.

I assume installing a midpipe will require cutting the stock exhaust off where the mid pipe and axel back exhaust meet?

Yes. I used this and got perfectly straight cuts on both pipes in about 10 minutes.
