From studying the APS website...I just wanted to confirm the exhaust configuration if installing this kit.

1) Starting from where the OEM exhaust manifolds would be, I assume the kit comes with turbo manifolds so "headers" would be no use?

2) Are the cats still in place? I can't tell from the pics but I assume both cats are eliminated as well?

3) The OEM Y-pipe is replaced with APS's own piping system that connects to the OEM midpipe?

I'm asking because currently have the OEM exhaust manifolds, OEM cats, and OEM y-pipe and would like to replace all or any of these components for now until I get the APS single turbo.

 

1) On the Single Turbo kit the stock manifolds are retained. If you use headers there may be a problem on the driver side with clearance between the header and the frame rail for the intake pipe. As well, the stock manifolds are better to take the heat. Aftermarket headers will not last.

2)Cats are eliminated

3)Yes the collector pipe after the turbo connects to the stock location of the OEM midpipe where the factory y-pipe usually ends.
