I can't seem to find my instructions.
The drivers side header is a standard shorty header. I forget the brand name, but Cartech didn't make it. I would think any unequal length shorty would work.
There are some fitment headaches if it is like the kit I have. I made a few "modifications" to it. The exhuast bypass is a PITA to hook up, as is the turbo onto the log header. I took out my air pump, and re-routed the exhaust bypass to make it easier to get at. Also, make sure you have fresh plugs on the passenger side. You won't be seeing them again for some time, at least until you take the down pipe, bypass, and turbo off again. If you still have AC, put fresh ones on the driver side as well. It's not as hard to get at, but still, no a joy. Also, your down pipe, if it is 3" like mine, will eventually burn through the AC line on the passenger side. Also, the intake pipe will sit on top of the turbo blanket. It gets REAL hot, I don't care what anyone says. I remade the section of pipe from the fender well to the throttle body and got rid of the blanket. Then I got a Cobra RR cowl hood and a 1" intake spacer. Now there is about 4" of clearence between the exhaust housing and the intake pipe. Other than that, it's great.
Really, I wouldn't trade it, I love the power it make, I just think it could have been engineered better. The turbo should go where the battery is, the cross over should be in front of the engine, and that would have eliminated many problems. I think they Cartech eventually did a kit this way. It make a lot more sense. Anyway, if you need any help, give me a shout and I can get pictures of whatever you need.
