Amazing build, I really like the level of quality in your choices. I guess you really build yourself a keeper, because even with your careful choices and decisions this must be quite a costly undertaking.
Love it.

Power
With Sharkwerks right in my backyard and the reputation they have built up over the years it wasnt too difficult a choice to work with them for increasing power on the GT3. When I first started the journey, headers werent available and at that time I wanted to try out their track exhaust.
Track Exhaust
Here is some fun track exhaust vids of my car. Turn your speakers up
Then theres also this at cruising speed and u get the idea how loud this thing can be, skip ahead to 7:28:
Adding this alone, there is some loss in the low to mid range, so i highly recommend you get the appropriate tune from Sharkwerks for the track exhaust which helps lessen this.
From having road tripped my car with the track exhaust from SF to SD, if you are cruising on the freeway over 80 mph, you will have drone, and it is loud enough to have your ears ringing if you are driving for more than an hour.
WOT you will scare people, but if you keep it between 2800-3200 RPMS, you can cruise around and easily have a conversation in the car or listen to the radio. Its all in how u drive it

The track exhaust began to wear on me, and I was getting a lot of complaints at my condo as well. Also with news on headers becoming available, I decided to try something different, with the mindset knowing I would be adding headers shortly after.
Bypass
While I do miss my track exhaust at times, there are more times Im happier with the bypass, including interstate driving, especially in stop and go traffic. My biggest worry when I went form the Track Exhaust to the Bypass was, am I going to be happy at all with this, and to answer that question, yes I have been.

Sharkwerks Headers/Cats and Bypass
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.
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.
The Sharkwerks/Evoms Headers come with 200 Cell cats. They are fully modular so you can remove the cats when you go to the track and replace with a test pipe, which is nice so you arent burning your cats out.
I also added the Carnewal Remote Valve switch so I could control the functioning of the valves at any time.
Here are some videos with the header/bypass setup
And dont forget the 100mm tips!
Autosea Carbon Fiber airbox with dual cone setup
Being that I switched to the .2 Cup deck lid, I needed to have a dual inlet airbox to mate up to it. The obvious choice would be to just add a cup/.2rs airbox, but I wanted to take that a little further. After talking with Autosea, they told me about their dual cone setup with carbon fiber y pipe that they had made for the cup/.2rs airbox. Again, being I always have to push things as far as they can go, I got them to agree to cover my airbox as well in carbon fiber.
Note: At the time I did this, the only dual cone airbox setup available was the 4.0rs. Recently there have been some new offerings that actually have increased the size of the airbox to allow more air volume to be able to pull from. I will be trying these out and selling my existing.

First off let me say that I continue to be amazed at this built Tye. You kind of hinted at the various things you've done to your car over the years, but to see all the details behind these mods... incredible.
Quick question... which Tranzit Blu kit did you get? Was it this one? Also, did you need a antenna adapter? thxs
