I have been thinking of getting the copper iso thermal mrev+ on my 06 couupe but I have heard of some weird whistling noises...Could I get some sound clips maybe? I dont want to have an anoying whistle from the mrev when its running....any help greatly appreciated

-thanks-

 

whistling = air leak.. If you fallow the instructions and torque everything in a gradual cross pattern then you'll be fine..

if youre in so-cal area and need any help give me a PM

 

not always; every since i got my iso thermal spacer from 3-4K if I get on it I get a loud whistling sound, almost like a s/c ...... no leaks here and it's only present in that 1 RPM band. I like meh whistling (plus other coupes with similar mods as me have it as well, so i know it's not a leak)

 

here too. whistles right when i get on the gas.

 

oh that noise.. who the hell would compain about air violently rushing through your intake manifold and being forced into the combustion chamber... mmm the sound of hp..

so in other words you mean its loud lol

 

the louder the better...

 

I get that sound from my Short Ram Intake too
I love it
ppl always turn their heads when it does it...

 

I have the same sound. I thought it was an exhaust leak since I had my HKS installed. But I only started hearing it since I installed my Stillen intake about a week ago. It wont hurt the car?

 

im not worried about how loud it is...I just dont want it to have an obnoxious wine..can somebody take some sound clips maybe?

 

Don't believe that's possible......most everyone is
slightly diffrent. In my case all these things add to
the sound of my G......Stillen CAI....Z-Tube....
Magnaflow cat-back and 1/2" MotorDyne ISO.
If you don't have these exact mods the sound will
change some what. I don't have a whistle, it's
more like the sound of a large holly quad at f/t
only higher pitch.

 

I get this weird whistling from the Ztube/K&N filter combo while under acceleration. I checked all the clamps and everything is tight.

Any ideas?

 

Maybe whisltling is not the right description because that implies air leaking out, thus the confusion with possible air leak problems. If you have air leak, then that's altogether different issue and NOT normal.

The sound that is normal after mrev/cai/ztube install is more sucking IN. Pucker up like you're about to whistle, now suck in air....kind of that noise. So, it should become greater when you accelerate.

 

hmmmmm so how do u get the whistling noise? cuz i would love some whistling noise when i accelerate

 

mine sounds more like a turbo spooling up.

 

Same here... I was hearing the same before I installed the MREV...
