GTM Test pipes for the VQ37VHR:
-Stainless steel construction
-Direct fit bolt on
-Extended 02 sensor location to prevent check engine light
Pricing and Purchase Information: GTM 350ZHR/370Z/G37 Test Pipes
so do all of the production ones include the extra o2 bungs for widebands, or were those just on the test versions?
They will also include the ports for future external wide band oxygen meters. The only difference between these and full production is that they will be polished, which will come at a later date.
Received my test pipes on monday and they look and feel like nice quality pieces. Got them installed and all I hear is rasp, really loud rasp my z sounds like a civic now how do I fix this I have intakes and stock exhaust.
Resonators perhaps. An experienced exhaust shop should be able to confirm your finding and add them in somewhere along the exhaust for a few hundred $$$. I am surprised with the stock exhaust though... Are you sure you do not have an exhaust leak?
Unfortunately we don't have any test results for the HR engine.
If you purchase a set from us, and we install them, I would be happy to give you before and after dyno testing (your car would have to have a stock exhaust)
