Headers with Stock (NISMO) Exhaust?
 

Has anyone on here installed headers on a stock exhaust? My car is a NISMO and I have resonated Megan test pipes, but I would be interested to hear your results even if your setup is slightly different. The main thing is if everything behind the cats is stock.

1) How does it sound?

2) Any significant power gains?

Thanks in advance.

And before I hear comments about not using the super awesome search function I tried that and it no worky.

There is Youtube video of what you are looking for on this thread.

I ran a NISMO OEM exhaust on my LTH for a year.

It sounds basically stock. A little louder inside the car, but outside, no one can hear you.

Thank you! Any power gains?

What, from the longtube? Yes. I put down 328 WHP.

My baseline with the nismo exhaust was around 297, but I did intakes, LTH and tune all at the same time.

Thank you!
