If kraftwerks would have just told us what the belt tension needs to be instead of saying use a sonic tension meter to determine frequency which is pretty damn hard to find. I could buy a belt tensioner tool for less than $20. Waiting on hold with kraftwerks to see if they know the actual tension value. |

UPDATE
Have I got some news for you! So Kraftwerks says to tune the belt to 60.70hz and doing so is really difficult for the average Joe. The official machines that measure this are complicated and cost a fortune. Well not any more... So I posted this free android app and got a chance to play with it. It's amazing. It actually works... This is for gates belts for bicycles. Here is my first test... Way off. So I started to tighten the belt. After this I locked the tensioner, fired her up, and what do you know... That sound is gone. I can also drive the car around and it doesn't really do it when taking off. A far cry from the 21mm in the install. Here is a video of what the belt looked like at 21mm and 23hz. [ame]http://youtu.be/J3Z4frpBR_w[/ame] So after all of this I think this method of belt tension should be advised. |

I need to get some logs to moto-mike now that I'm full of e-85 but his tune has been rock solid. If Kraftwerks did the math and came up with 60hz then the belt shouldn't break where it's set now. I trust this application since it's basic math to determine the sound wave. One thing that does bother me though, the tensioner system really sucks on my kit. I over tightened it accidentally and loosening it was a chore. I had to hammer the thing with a piece of wood very hard to make it move at all. I applied some grease to the tracks to see if that would help but it didn't seem to help. Maybe the tolerances are too tight when it's cold. |

I will be buying in a couple of months, do you guys have any problems? did it works better with a aftermarket header than stock? I have ultimate racing 3" exhaust with 3" overpipe.

Quiet is pretty subjective I guess. I purchased open flash header #11 and had it on my car for two weeks before my wife asked that I change it back. I tried it with stock exhaust and with my Q300 and it was too loud for my suburbia neighborhood with ally garages. Was a great header and might be quieter than other cat-less headers but I think I'm stuck with the cats unfortunately
