Look for some updates and added features to the site this late dec09-jan10. We are going to relook over the whole site and all our products to make sure all information is correct and all the pics are up to date as we all ways are improving our products. Making that a little harder is going to be the fact that our back up hard drive crashed so a lotttttt of pics and info was lost. But over time we will get everything back. So if you have any suggestions for the site just send us a email because we are always looking for constructive criticism. Also look for some t6 hotsides to pop up on the site. We have been building them for a while but we mainly just build them for our customers that have the car at the shop. We will have 2 basic locations. One will put the turbo on the passenger side with the compressor inlet facing the stock air box area. The turbo will site in between the radiator support and the engine. We have for up to a 91mm turbo in that spot. The other location is going to be on the drivers side with the turbo inlet facing the battery area. So depending on what you have going on under the hood you have 2 options to choose from. But we do get a lot of request for them so we will be offering t6 hotsides that use our "R" series headers this spring.

Also going to be added to the website is going to be some more info on the history of the yellow notch as that seems to be a pretty popular question from callers and emails asking about the combo of the car and different combos that also worked nicely with the car. I'm sure some people will remember the car from being a twin turbo car with a 5 speed to a stage 2 "original" single turbo notch with a aod that was mainly street/strip to its current combo that is a stage 3 b series kit with a c4. So I'll go through some of the pages with my opinion on what the pros and cons were for each combo. We are also adding a new phone number to contact us. Its 586.372.8866 and as all ways for the best tech support ask for Jeff

Ok, So far I went through all of the header and downpipes section and everything looks good. Look for some new pics and the addition of the "r" headers that have the collector going straight forward on them prices at 399.99

With better tires (28x10.5x15 quick time pros) and a little more boost the car ran a 9.75 @ 138 on pump gas with 8* of timing on the factory computer.



Just added to the line up of headers is our "R" headers. They are 1/2 flanged, 1 3/4 primary headers with the collectors on them with a 3" v band ring welded on. You now have a choice of 2" (sbf), 2.75" (trick flow), 3" (others 1487 gasket), and high ports flanges that we can do for NO extra charge. Great for t6 builds or any custom build where you need the hard part done and can finish the rest your self. No more wondering if our kit will clear the items you all ready have in the engine bay.. Starting at 399.99
