V6 X-pipe VS H-pipe flow test

Cyber370

The Ark exhausts have 2.5 diameter piping and probably the nicest X-pipe in the industry. It’s what convinced me to go with the Ark DT-S. By the way, the Nismo OEM system has an X-pipe not a H.

According to this thread it's an H-pipe as found on the R-Tune exhaust.

I stand corrected. Just went and check my Nismo OEM exhaust in storage and it is an H-pipe.

You are correct. It is an H-pipe. I had the R-Tune installed. I drove a new Nismo before I bought the R-Tune. I may be half deaf, but I couldn't hear much, if any, difference sound in sound between my car and the Nismo. There is a huge difference in sound between the stock Nismo exhaust and the R-Tune.

It is a little louder than stock, but it is MUCH more melodious. I can't tell any difference in power, but I mash on the pedal more just to listen to the music.

I decided to go with the Nismo R-Tune Exhaust because it is 2.5" and the fact it's Nismo. I felt that it's only right to put a Nismo exhaust on a Nismo. The exhaust also uses an H-pipe. I really wish I could do back to back dyno with an X-pipe vs H-pipe to see which makes the most power on the cars. But I think the power is negligible. I think it all comes to sound.

Please post feedback after you get it installed! Does it take away from any of the high-pitched VQ whine?

The exhaust on the car currently is a Borla S-type which was installed by the previous owner. All I can let you know is what it sounds like now and what it will sound like. I'll do a before and after video of the sound.
