Add in Jemini as the company is a vendor here. And also getting a good dyno on these cars is not perfect.

 

You won't get a good answer if you're looking for the exact dyno numbers. These CVT will obscure the output readings. Unless you see some numbers from someone with this car, with a manual tranny swap, run the before and after dyno for both y-pipes.

However, I installed the JPP two months ago, it's greatly improved the response. I come from several maxima's so far, these Y-pipes on the 7th gen easily puts out 15-18HP gain in my opinion. Also fuel mileage got better by 1.5 from the display panel, I've been watching it like a hawk.

To answer your other question in another thread, yes, installing any of these y-pipes will definitely void your warranty because the post catalytic converter is omitted. If it doesn't, I'm sure the dealership will find some excuse to say it does.
