V6 X-pipe VS H-pipe flow test

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.
