Drivetrain ABF Tech Division R56 turbo back exhaust system
Looks like you spent a lot for it then. Then again, it's for a bike; bikes are damn expensive regardless.
Touche, it was hydro formed aswell so thats where the money goes.
I like the look of the welds through instead of bends.

I guess I could formulate a reply if what you stated made any sense. What are you talking about? I never stated nor insinuated that I have an issue with how a company spends their own money. Not sure where you are coming from or where you are going.
the welds are done like that way it's stronger. Bending Ti makes the walls weak, being that it's already pretty thin they didn't want to take that chance.
If this ABF exhaust was Ti and still priced at $1500... then I'd consider.
We thought about a titanium version. The problem we face is sound quality though. Since the exhaust is long with few bends it may sound very tinny and drone a lot. As you mentioned Ti is thin so there is not a whole lot to absorb sound or carry it though the pipe. Depending on how well this current set up sells we may make a axle back Ti section for aesthetics though.

On a professional level, I agree with you, it's a bit much. But being that there aren't many Ti exhausts for STI's, this was the best looking one and best priced. If I could change the tip I would.
Like I've said before: performance over looks. This exhaust weighs 16 lbs, compared to the 40-50 lbs aftermarket exhausts for the 08+ STI. Lightweight is what I'm aiming for. My car stock was at 3360 lbs; last I weighed my car (before CF hood, FMIC install, EL headers), my car weighed about 3150 lbs.
Working on it. It was raining on and off here last week so we couldn't really get a video shot. The weather looks good now so we are tying to get one shot asap. Dyno is all done though and i should have the graphs converted and up today or tonight.
Sounds good. I'd definitely like to hear a sound clip.
I bet that's not the only thing you wish your wife would let you get your hands on.
You can get a glimpse of her here....but that's all you get...
....her car and mine too
The noises coming from the exhaust are awesome too!

The MSC we used only had the JCW Tuning kit (OEM upgraded intake, axle back muffler and tuning software). We did the base line with this since that kit pretty much gives the same results as stock. From there the the AP was added and run with the same intake and axle back. Finally the turbo back was installed and run with the same AP and intake.
The videos are of the same 2010 MCS car in the third and final stage of these test. JCW intake, Access Port STG 2 map, and our Turbo Back Exhaust. Thats the only engine mods to that car.
We have a graph for stock only before and after the turbo back. It will loose both HP and TQ on the low to mid range, below 4600. After that it starts to pick up and gets about a 10 HP and 10 TQ gain up top. We did not post this graph because it might be misleading and we only wanted to show graphs of the exhaust being tested using the intended form of installation.
The R56 likes to run rich with many high flow cats and especially no cats at all. If this is a type of modification one would like to do to their car then tuning should be expected for proper function. Luckily we took care of tuning part for AP owners, so it's as simple as installing the exhaust and loading a new map.

We designed it with the Access Port or a like tuning device in mind because tuning is required for a catless exhaust to work properly on a R56. Since we support and use the AP, we already know the Alta Stage 2 MCS map is written to support up to a 3" turbo back with high flow cats.
We used the Stage 2 MCS map as the starting point and had Cobb pro tune a few of the cars to build an optimized version. We got some power gains from this, but was done more to fix drive-ability issues that occurred when using the base stage 2 map.
This updated version of the stage 2 map is provided with purchase of the Turbo Back.
