Got my Labree fullback on Friday

**jaykato** · 06-01-2008 10:24 AM

Sounds great. Perfect sounding outside the car. Only problems is that there is an insane amount of resonance in my car around 1500 rpm. I have a tip and its right about 35-40 mph, which means any back road usually puts my in that range.

Any suggestions? Any one else have this problems and fixed it? I read in the A4 forum that vibration of the clamps or the exhaust could cause this.

Other than that, I cannot complain about the workmanship and sound. Perfect sounding both inside and out, just has that resonance issue.

Nice, i called Labree about there catback about 2 months ago but havent pulled the trigger on it yet. Where are you located in NH?

Hampstead.

You should do it. It sounds great and construction is top notch. I think the resonating that i am hearing is just the tubing touching some metal on my underbody.

It seems every aftermarket exhaust for the V8 S4s resonates/drones to some degree in the 1500-2000rpm range. Milltek less, Labree and FI more. I have a Labree resonated catback and there is a loud drone in that range. That being said, I spoke to Brent Labree about this and he mentioned the Tiptronic cars drone even louder than 6MT. I forget why exactly, but that's what he indicated. Give him a call and he can explain better.

that's why you buy a 6spd! none of the exhausts i've had on my car drone after 2.5k

Mine doesnt either, the drone is right around 1500-1800 RPM. I moved the exhaust around a bit and eliminated most of it, not much of a big deal any more. There was a slight rattle on the heat shield in the back and also I think it was vibrating near the rear axle on the driver's side. Move it around, resonance is almost completely gone.

Not to get into the debate between 6 speeds and tip, but I am so happy with my tip after trading my B6, which had a manual. The smoothness is much better, and even though at times I missed the manual transmission, not enough to go back to the jerky, shaky, higher revs at speed 6 speed transmission.

I have the AWE B7 resonated catback for my tip and have exactly the same issue at 1500 rpm.

Ditto with my 6spd B6S4 AWE Non-resonated catback...a bit of drone from 1.5k - 2k. Ohh well...

After close to a week, definitely gotten used to it. I can switch to sport mode and the RPMs are held just above the range where I was getting resonance, so that definitely helps.

The advantages of the exhaust outweigh the slight drone, I absolutely LOVE how it sounds and I have no doubt noticed much more midrange pull. All and all I am very satisfied.
