FabSpeed exhaust install
 

So, I purchased the FabSpeed exhaust from Maxster on the board- Much thanks for a great transaction and a fun afternoon tasting wine and eating Sea Bass.

Now for the exhaust. Installed it today. The construction is absolutely gorgeous on these parts. Install went very well as well. Now the problem. FabSpeed claims this is a "no resonance" exhaust. Well, apparently that is not true, at least on my car. I have significant resonance between 2000 and 3000 RPM, not at all what I expected. It sounds great during spirited driving, but is obnoxious at the aforementioned RPMs while cruising.

Now, what I'm wondering, is will changing headers improve this situation at all? FabSpeed did test their full system when they stated that, so might that have something to do with how they claim it to be a no resonance system?

Fabspeed has two different exhaust for Boxsters. They had an older styled one(wholes drilled in the exhaust tips) not too fat off the OEM design but it was discontinued. Then they have a newer styled one like they sale on their website. Which did you buy?

That system has a lot of resonance?? Judging from fabspeeds video that thing sounds almost stock quiet. Is it really a lot or were you expecting it to be the same as stock between 2-3K rpm?

This one (maxspeed), I assume is different from Fabspeed?

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?

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.
