Introducing the extremely limited and rare, and absolutely AMAZING! Sharkwerks/Evoms Headers and 200 Cell cats. Fully modular so you can remove the cats when you go to the track and replace with a test pipe.

After going from Track exhaust, to Bypass, and now Bypass plus Headers, I can say this is the best combination. From a sound perspective, there is ZERO drone. This thing is track exhaust loud when WOT, yet bypass quiet when just cruising around. The best way to describe it is imagine being able to turn the volume up on the bypass. At WOT, the sound is a very clean wale, much cleaner sounding than the track exhaust which i thought was a little muddy.

Since I have a lot of track exhaust vids ive posted before, Ill get some videos of this so you can see the difference.

More importantly than sound, with the retune optimized for this setup, there are significant gains across the range. The mid range pickup is significant to tell by the butt dyno, where i dont feel the need to have to gear down if im not in the ideal gear.

There is a dyno showing the gains on the 3.6, but let me get Sharkwerks' permission to post it first. But I will say this, 997.2 GT3s (not RS) watch out.

aw thanks Tye For those that don't know he's got an INSANE stockpile of weapons grade modifications at the ready haha:P

Here's kind of sort of what these cars sound like with our bypass and the evoms headers:

Dyno of 3.6 Tune, Headers, and Bypass. Peak numbers were not the goal of this tune, more so area under the curve and improvement across the board. Im very happy with the results.

Hahah, I guess i do. Full build thread coming soon.

No they don't. Sharkwerks worked with them to have these done. They only had time to make 4 sets, hence why I called it the unicorn. Sharkwerks doesn't have them on their site either. Besides my car, one set is on Alex's 4.1, the other on the black 3.9 build in the video Alex posted above, and I can't remember who has the last set.

I'd be curious what it sounds like (and whether it drones) with the heavy side mufflers removed and an Akra or M&M center muffler only.

+1. Also, what's the diameter piping on these headers?

EVOMS

We are working diligently on bringing more of these headers into the world. Stay tuned!
