Active Autowerke | F8X Exhaust System and Mid-Pipe Technical Overview

amb99 · 01-22-2016, 03:47 PM

I am runing the AA mid with the stock rear and so far I am very pleased. I get to maintain the use of the exhaust flaps when I have to tote around a client and the butt dyno tells me there were definite gains with the mid only. Active8 tune is on the way with a set of black Active tips..

I take it that it was a bone stock car with JUST AA mid and rear. NO catless downpipes.

All of our F8X systems are hand made here at our facility in Miami, Florida. The fitment on each unit is tested prior to shipping, and with in house quality control we can ensure that each system is manufactured to our standards.

Post is in desperate need of some sound clips especially of the claimed smoother sound delivery - realize very hard to capture on most recording devices but a comparo with stock at least would be very useful - Thx! May already be links o the forum to this - sorry have not searched yet!

Looks like tune has an advantage

I have bms intakes, else stock with 93 fuel. Should we have some fun!? I'll go to MAP here in MN and run a few dyno pulls after aa cat back install?

Might have to do an over under on my hp outcome...? ??

I have been a fan of their exhausts on all platforms but this exhaust is by far their best

Is it possible to install the AA mid pipe with ER DP and OEM exhaust without cutting or making any other mods?

You can install our mid pipe with the ER DP with no issues. However, since the OEM exhaust is a single piece (the mid section and muffler are made as one unit), you will have to cut the rear muffler section off and attach our mid pipe via OEM BMW clamps (the same way you would install a BMW Performance muffler).

It's unfortunate they chose to make the original exhaust as just 1 big piece. Kudos to AA for the great pieces though.

Here are some clips if you are interested in hearing their exhaust with catless downpipes...

I think a lot of people want to hear some good sound clips of your AA mid-pipe with the stock rear muffler (under load / driving) with valves open and closed. Obviously deleting the secondary cats and the X-reso box makes the sound louder but would be nice to gauge how your mid-pipe changes the raspy sound of the stock mid-pipe. Maybe I should be the guinea pig and make some nice vids!

Love this exhaust

Can't go wrong with the full system or just midpipe and downpipes!

Charlie@McKennaBMWService · 01-26-2016, 05:36 PM

Hey David can you shoot me a PM about this exhaust? Had a few questions.

There's a good bit of info on this system on the forum. I've been running it since day one. Anything I can help with?

If it's about pricing, he's the man to talk to!

RussianPete · 01-27-2016, 08:11 AM

It was definitely loud in the shop, although I can still think of something that's even louder
