I tried all the quiet CBEs: Prodrive Oval, Greddy EVO2, Borla Hush. They will all drone on the highway if you are completely catless. No way around it without custom midpipe with resonator or hi-flow cat. I finally went with STi CBE and am 100% satisfied. At my power level (VF34, Pinks, Cobb AP, TBE) I doubt if I am down on power, but even if I am it is less than 5whp. Well worth it to be rid of the drone.

We talked about this a little bit when I got those struts from you.

I run a Perrin and get very little drone.

My suggestion would be to either get a different exhaust if you're not totally stoked on it. Or go get yourself some insulation and insulate the spare tire well and the rest of the back as well. That will make it all much quieter, if you want to stick with the exhaust you have.


Personally... I'd like to get a mad dad dual whisper.

 

i love mine

 

know anything about that catted one piece down/midpipe???

They don't communicate to well on the forums... and I just don't care to call..haa.

 

thanks for the helpful link.
how much do i need of raamat and ensolite to do the cabin area?

 

yea, i am suprised you dont get much droning from the perrin as it is pretty loud compared to the hush.
im gonna try to add some sound deadening to the rear cabin. if that doesnt help much, im gonna get another exhaust.
tahoe trips are just gonna be unbearable

 

Looking up the order, I bought the following for the cabin area.

• 2 Rolls Raamat
• 9 Yards Ensolite
• 4 V&S Spray Adhesive Cans

Had about 1/3 roll of Raamat and a couple of square yards or so of Ensolite left over, plus a can of adhesive. I did less than complete coverage of Raamat on the roof and floor, and inside and outside skins of all four doors, with extra behind the speaker areas. I'd already done the cargo area floor, of course. Did also do the lift gate, though, which I'd skipped previously. I'm guessing that amount would be enough to do that, too, with a little still left over.

Took me most of a weekend to strip out the interior, do the job, wire in a set of front component speakers, under seat amp etc., and put it all back in. As a bit of advice, don't do the driver's side door first when getting the hang of the doors. It's the one you want done best, after all :-) And if you're ever thinking of changing out your speakers, this is the time to do it.

 

Turn the sterio up.

 

wagon with borla hush - header - helix catted DP no drone the knocking from my coilovers is more noticable then the exhaust

 

aren't you running catted though?

the perrin exhaust is horribly loud when attached to a catless up/dp.

 

Helix up and CATTED down with Greddy EVO2, along with GT Spec header, not that bad at all... it doesnt even bother the wife.... which is saying alot !

 

this reminds me, it'll be interesting to see what drone is like on the 08's

 

mine used to drone, now I have RA gearset not only am I in a high enough RPM its not in droning range, but the noise from the gears drowns out the exhaust lol.

 

3300RPMs at 65 mph, gotta love it! its actually keeping me going the speed limit when I go from Monterey to San Jose

 

WREXNFX and Shagon Wagon - You both have cats which makes a big difference. My Prodrive was fine when all I had was the catted uppipe. As soon as I got rid of that, drone city.
