Forced induction and OEM exhaust

Boosted Performance

Soooo, as I am sure many of you have seen the single turbo build I am working on here. If not:

Boosted Performance single turbo build

Today I had a closer look at the OEM exhaust system, and can't see anybody using this in conjunction with any forced induction system. Since my customer has the F.I exhaust system, and it seem a lot of people on this forum have it as well, I was thinking that I should not even bother with a down pipe that would bolt up to the OEM Y-pipe.

How many aftermarket exhaust systems are out there for the 370z that do use an aftermarket exhaust system that would bolt up to the OEM (or aftermarket) Y-pipe?

I see that Tanable makes one:



DC sport:




and Litespeed:




How popular are these exhaust here? These would bolt up to the OEM Y-pipe so I would have to build a separate down pipe for an exhaust like this.

Feedback is greatly appreciated.
