Cant wait to see what you come up with for headers. Are you planning a catless and a 200 cell set?

We are making some progress on the GT4 and I can't wait to put some more miles on the car.
Our plan is to take it to Thermal on Dec 16th with the following upgrades:
-Headers and exhaust should be done by the end of next week with dyno comparisons to stock
-We are also working with GIAC to complete a tune for this upgrade, more info to follow on this...
-BBS is working with us to supply their 19" setup for track use with Hoosier R7’s.
-We already have our harness bar shipping to our dealers around the world...
-Lastly, and most importantly, we will have our setup on the car which drastically affects the handling of these cars as they need some attention after their initial PDI at the dealership.....

We will use our knowledge gained from testing the GT3/RS for the past year.....See video here from Thermal:

James, are y'all planning to run a GT4CS next year? Really excited to see how the headers/exhaust work out. Someone needs to get the cork out of this thing, you can really feel it.

Our plan right now is to run 1 CS in Pirelli Trophy Cup and then acquiring another one later in the year to enter the final rounds of that series.

In Conti, the CS will have a tough time competing against the Mustang's and Camaro's so I will be routing for CJ and his boys and they are going to be the first to crack the whip in that series.
We should have tons of data on the CS on Pirelli's.....

But yes, we plan to get the most out of the exhaust upgrade, mainly for the street and then a catless program for the track....

Will you be offering the bbs 19" without the Hoosier r7s?

ahem. currently testing...



boxster spyder day 1 at CJW Racing shop...

we will have dyno'd exhaust solutions in a few weeks. plan is to run everything on the spyder and once our race cars land do some side by side dynos. will start a separate thread to keep everyone posted. The 3.8L engine has a lot more power potential than 385hp.

Can't wait to see the results of the headers and exhaust. Been wanting these upgrades for awhile. Will you be releasing the catless headers at the same time?

CJ that Spyder is gorgeous, love the interior too!

I'm in for headers and exhaust on my GT4, preferably without the need for a tune. Need more power to help make up for my crappy driving.

We should have the headers done and on the car within the next 2 weeks, plus we will be testing the car at Thermal shortly thereafter, along with some different tire setups as well as our chassis setup.

Our first setup will be with the 200 cell cats and then we will have the catless setup.


More to come....
