quick question.......do anyone of you know if a off road pipe (straight pipe for cat) for a GST will fit on our cars with the star kit??? i know the exhaust work...........i don't think it does, but not sure.....guess i'll have to get one fabricated.

If the flanges rotate 360 degrees, the length is all the same. My testpipe fits GSX/GST/GS/RS. testpipe.com makes them all the same.

It'll have to be modded a little to fit. You'll notice when you get under the car that on one side of the racepipe the flange will not bolt up correctly. Its a simple fix though. I just marked on the racepipe about where the holes on the flange should line up, cut the flange off and rotated it till the holes matched where I marked and TIG welded it back to the racepipe.

Be ready for the power to come on strong as hell though. Especially since you have built internals and I'm sure are running high boost. I used to drive around day to day with my racepipe, but I kept losing traction whenever I hit the boost in low gears. Really, the boost would come on so strong I would spin the tires already going 30mph. Plus it made the exhaust loud and eventually unbearable. My take on it is HP with a racepipe in isn't progressive at all. Its pretty much an 'on-off' affair, when you boost hard it will IMMEDIATELY load up the tires. If you can get your car to hook up then go for it cuz it will take off like you wouldn't believe. If you find you are having problems hooking-up then it will just prove to be wasted HP and might be better off with a high-flow cat.

I just use mine at the track now since spinning the tires is not an issue there.

Hey Patrick, what boost was that 13.49 ran at? And were you on street tires? Thanks man....

Strauss,
The 13.49 I pulled was last year at Maryland Intl Raceway. I was boosting 16-17psi, on balding stock street tires inflated to 18psi. I think I was hitting consistent 2.2 60fts that night and finally hit a 2.19 on this run. I think my peak egts were around 790C. Alot of people will say running that rich kills power and to turn up the boost, but I like to play things safe. I was also shifting around 6K rpms. Not as a safety issue though but more b/c from all the various dyno graphs I've seen and datalogs I've done, timing and power significantly drop off after 6K rpms on 2GNTs.

Here's a pic of my timeslip. Doesn't it figure, too, on my best run of the night I lose to a slower car....I hate bracket racing x(
