I meant to copy and paste it in a different thread,my mistake.

BUT Maxspeed did(not their current) sell a copy of Fabspeed's old Boxster exhaust,which reportedly didn't have any resonance.

I have the newer style FabSpeed exhaust. Like I said, the quality is amazing, and from outside the car, and inside above 3k is just about perfect. But, it does have resonance from 2-3k, which I was REALLY trying to avoid after coming from the GHL.

This is on an 02 S 6-speed car.

Would you say it has more then the GHL?

[Cloudsurfer]

No, its definitely less resonance than the GHL, but I was hoping for zero resonance as advertised

I don't think there is one single muffler out on the market for any car that has zero resonance and flows worth a damn. There is a lot of bs out there in the exhaust market about zero resonance and 50hp gains etc etc. Even the oem muffler has a tiny bit of resonance under certain loads at certain rpms. If you want a louder muffler then you have to accept an increase in cabin resonance as well. It's a package deal.

I am well aware of the tradeoff between increased flow and performance and the likelihoods of resonance and increased noise. I want the good noise, I dont want the resonance. I specifcally chose the FabSpeed as everyone claims its resonance free. I wouldn't mind a small bit, but this to me is definitely more than I had planned.

I did talk to FabSpeed, and they confirmed I shouldnt have this problem, and am not sure whats up with my system. I am going to send them some pics from under the car next time I'm under there.
