Hi ... are they compatible with HFC downpipes?
In particular these: Envy High Flow Catalytic Converter HFC, VQ35HR VQ37VHR
- Giovanni De Paola
Hi Giovanni, they would not work with HR/VHR HFCs or test pipes, they will only work with DE pipes.
Is there another way to make these headers fit on the HR 350z rather than using test pips/cats made for the DE? Just got the Motordyne art pipes, would love for there to be a feasible way to make these headers work with the art pipes.
- Daniel
Hi Daniel, the only other way would be to cut the flange off your test pipes and weld on DE flanges. That's the only difference, and the only reason it requires DE test pipes--these are only available with DE flanges.

I have a g37s with invidia test pipes and would like to get the tomei headers ,is there any way to keep the test pipes that I have and do some fabrication to make the headers fit?? Or is it physically impossible?
- Daniel king
Hi Daniel, the only difference is the flanges where the headers meet the test pipe. So you would need to swap the flanges on your test pipes for DE flanges.

Hey guys, I drive a 2008 g37s. I read about having to have DE test pipes from header to test pipe. I have an aftermarket exhaust for the g37.
Would I have to change out the exhaust as well since I would have to get DE test pipes? So from bottom of test pipe to exhaust? Thank you
- Miguel
Hey Miguel, you would only need the DE Test pipes to run these on your car. The rest of it (Y-pipe and back) is all the same from there!
