GTM Performance Engineering VQ45VHR-Our Journey to The 1000 HP and Beyond

On the exhaust, I don't fully understand going to 4 pipes that far back. Seems like extra weight and no more performance. It does look amazing, but what was the design decision? The only thing I can guess is that it has to do with controlling the total sound output somehow, though I doubt with those tiny resonators that this thing will be quiet...

The car has Quad exhaust simply for the reason that the body kit calls for a quad exhaust. If people like the exhaust and want on of their own they can call GTM Motorsports and setup a time to have one made for their car.

Car is also VERY low and that tip location is higher than stock so a "traditional" muffler probably isn't going to fit. But basically it just looks really cool.

I guess my point is if you wanted quad tip you could have easily welded two dual-tips at the end of two pipes and shaved the weight of the extra two pipes and resonators.

Who cares about a pound or two for some pipes if you have 1000hp to play with...

Do you think that the GTR manifold might benefit the N/A guys as well or is it better suited to forced induction applications?

I don't even know if it benefits the FI 370z guys. Maybe GTM will chime in on that.

We are just now entering into the testing phases with this manifold. the next few weeks will reveal a lot of great information. Sam and I are both very optimistic about this manifold and we believe it will be great for the FI guys.

As far as NA guys are concerned I would not expect huge gains from it like we will probably see with the FI applications. However, We dont know yet... Sam and team are working on SEVERAL "TOP SECRET" projects involving the GTR intake manifold....

So stay tuned guys there is plenty of work that still needs to be done. From my discussions with Sam you guys will be getting a GREAT conversion kit including a cast lower intake manifold!!!

Thanks for taking the time to respond, I should have held my excitement until you guys can actually get it tested a bit! It certainly looks gorgeous in the car though, I really can't wait for the final results.
