Exclamation ||| Active Autowerke E8x 128i Signature Exhaust - Development Thread |||

Hey guys, as many of you know we have been trying to develop an exhaust for the e8x (N52) 128i models. We were able to get a member's car in our shop for us to get the appropriate measurements, testing, and be able to design an exhaust specifically for the 128i. I thought it be cool to document the whole R&D process and share it with you guys. Hope you enjoy it.

All we did today was take measurements, and see where our starting point is.

Stay Tuned for daily updates.

From what AA has put out for the 135 and 328 models, it would be a good assumption that it will be an axle back.

Can't wait to see daily updates. This will be a good teaser thread to subscribe to

Exclamation Update 1.31.2014

Ok guys so here's today update. Even though as you can see is a busy day we are still managing to put time into the exhaust's design. As you can see in the pictures we are still in the preliminary stages, keep in mind this is just a prototype still. I will try to post a sound clip later on today. First we were going to start from the 135i/328i exhaust design and modify it, but since We are trying something new with this exhaust in regards to the design, we had to start from scratch. STAY TUNED!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

It's good to see more support for the 128i! I'm so looking forward to how this sounds! Is this planned to be a catback exhaust or just the muffler? Or is AA planning to do the exhaust manifolds as well?

I find it amazing how you guys can be able to make an exhaust that quick, within a couple days and basically have a finished product.

Absolutely amazing.

Cannot wait for sound clips!

Couple of questions.

First what is the size of the pipe? I keep thinking the single outlet from the muffler should be about 3 inch diameter to match the two pipes coming into it in cross sectional area.

Second, I don't understand what the Y is about. Are you dumping part of the exhaust under the car? If so, why and what about safety?
