That's just the angle of that video. FI uses two angled cannisters, not one single center mounted muffler.

Before I order the test pipe, I want to ask you something. I am thinking the ERZ test pipe. How about this one? I just know from this forum that the ERZ stuffs(including the HFC and the test pipe) are mhch cheaper than Stillens, Berkes and so on. Do you think what test pipe is the best? I think that this is also a silly question. ^^ Please, give me your professional opinion! Thanks, Rhett in Seattle |

I have ERZ HFCs on my G37 sedan. Love them. They were raspy with the stock exhaust, but once I installed my Fast Intentions system, the rasp totally disappeared.
There really isn't much difference between test pipes. They really are just straight pipes. Compare the materials used though. Some use better stainless steel. As far as performance, there won't be any difference regardless of brands. I would consider resonated test pipes, to cut down on the rasp. Adding a resonator in no way effects performance, other than sound. |

What he means by it not affecting performance is that adding a resonator won't Detract from your performance. Even though an HFC doesn't have as big a Cat Cell as a stock cat, it still does have something the gasses have to pass through. So some performance will be lost. Resonated or non-resonated test pipes have Nothing in the way to block the gasses. Free-er flow = more performance.

BTW why are some people excited by the HFCs even though some performance may be lost? Only reason is to get rasp sound from the HFCs with lower cost? |

what is the different between w/ 12" Resonators w/ 18" Resonators
just a sound? which one is louder? What about the performance? any power gain or loss? and what is O2bung, what is it use for? and what does it mean polished by stainless? Any different from the normal one?? Does the carbon fiber give different sound from the normal one or just the look?? Last edited by OhYeah; 07-06-2010 at 12:13 AM. |

There is NO performance difference between 12" or 18" resonators. The resonators only affect sound volume.

12" is a good bit louder than the 18". 18" has a deeper tone, though.
