1. if I ordered YOUR s-pipe+exhaust would it be compatable with your turbo kit? and make together make a full aftermarket turboback exhaust?

2. if I were to order stage0 it would be upgradable to s1, correct? if so, are you going to come out with a stage0 to stage1 upgrade kit?

 

Yes the exhaust and spipe are both compatible. I have the stage 1 kit and will be purchasing both. Should be a nice power gain. Yes the stage 0 is upgradable to a stage 1 and ZPI will be offering and upgrade kit from 0 to 1.

 

cool, thanks.

what is the diamter of the ZPI exhuast? 2.5 "or 3"

 

2.5

 

hey mattssi, it looks like Iam pretty much doing the exact same as you. How do you like the ZPI kit w/ spipe and exhaust?

 

I'll tell you in about 2 weeks when I have all the parts ;)

 

I don't have a kit yet. I have a lonesome S pipe sitting on my pool table - that's it.

 

isnt a downpipe and s-pipe the same thing?

 

nope

 

A turbo downpipe is the pipe from the turbo to the s pipe.

Otherwise, in an NA tC, the down pipe would be the s pipe.

 

so is there a need to replace the spipe or does the stage0 setup already come w/ the piping?

 

You can get an S pipe w/ stage 0. IT replace the most restrictive part of the exhaust system (factory S pipe)

 

The turbo kits do not come with an s-pipe... the downpipe in the turbo kits basicly replaces the rest of the header. (meaning the turbo mani and turbo then downpipe would be where your stock header would be)

 

oh ok - then it is important to replace the s-pipe - eventhough thats another 200.00. hehe

 

You should be able to make good power on the stock s-pipe, but yes it's a good thing to replace.

Our original dyno plot was with a stock exhaust, with the exception of a cheesy universal muffler welded on in place of the stock muffler.

 

The s-pipe is very restrictive. you will see a good gain in a full exhaust header back system
