How loud is it? Can you hear it outside the car? I went underneath an overpass today with the window down and let off the gas; I was surprised to hear the ratlle echo through the tunnel. It's definitely got louder recently, almost to the point where I'm embarassed to let off the gas because it's so audible. I know Mitsubishi will do nothing about this too, especially seeing as I don't have the stock clutch .

 

On my cars its always been super loud - I even changed the entire drivetrain out to my spare set up out of a wrecked car with 300 miles and it still makes the same noise - I got used to it !

 

pretty loud

 

noticably loud

 

Does the deceleration noise stay if the clutch is depressed? Is the noise only when you are decelerating at certain rpms? Mine does this and it does seem to have gotten louder. However, I have owned 3 AWD DSMs and two WRXs, and every one of them did this to some degree. I think some of what you are hearing is backpressure in the exhaust. I've heard it reported before that people have switched to stiffer exhaust hangers and the noise has decreased.

 

Very quiet, barely noticeable at all.

 

Sound completely goes away if I step on the clutch.

 

My noise goes away too if I step on the clutch, but it also goes away with the slightest tap on the gas when the clutch is still engaged. Hard to say if it is all drivetrain, but I think from previous experience, it is part drivetrain, and part exhaust. Interestingly enough, my wife has a 330xi BMW which is AWD as well. That car does make some of the same noises on decel as well. I think alot of what we hear is the differentials working in the AWD system. That noise started in my DSM AWD at like 50,000 miles, and it still making the same noises now at 90,000 miles, and this was after a brand new transmission and transfer case as well as rebuilding the driveshaft. Everything works fine, but the noise is always there.

 

Mine's loud. A bit louder than other Evos I've ridden in.

 

Seems to have gotten quieter over time...or I'm just used to it and don't notice it anymore...

 

Same with me. But I also have other noises coming from interior pieces to listen to if I don't want to listen to music!?

 

It is the drivetrain and gears. Get used to it because it doesn't go away.
I dynomatted my doors for my soundsystem and that made a big difference as far
as car noise.

 

How can you fix this? What is the cause? I am having the same issues!

 

A lot of the noise is just clutch rattle/buzz which is nothing out of the ordinary on Evo's (and some other performance cars such has the Honda S2000).

 

I have the same issue! Anyone know now what the cause of this is!
