How come you want to get rid of them?

 

Material cost around $1000, give or take, Im running the stock exhaust, which can barely be heard unless the windows are open. My main reason for the dynamat was for the audio system.

 

are you talking about the exhaust being loud all the time or is more of the drone.

I ve had the same problem on two differnt suv's in the past. You hit a certain rpm on the highway and it drives you insane. My G500 was 2300 rpms... It was like open headers... anything over it was quite. The CLK was 2000 rpms, and the suburban is 1800 rpms... I think they car it resenatance or drone in the exhaust world.

You said its custom exhaut, have you looked into adding more mufflers?

The dyna mat does work well, i used it in the sububran.

 

I have that exact same problem from 1500-2900 rpm it sounds like idont have any mufflers and drone but over 3000 it sounds perfect

 

id see if you could put some cheap mufflers before the mufflers you have now. Look on like jegs or something

 

I don't need them. I have my primary CAT's that's enough to pass SMOG here in Cali. I'm running primary's with bypass pipes.

 

so you think i should add one more muffler?
Have you done anything to fix the problem

 

I put the stock one back on the suburban, it runs the truck exhaust and apparently the world is full of cowboy bednecks. Im looking into do something custome

The problem with the two mercedes was we removed the resonator, I dont know if the porsches have them.

In theroy thogh more mufflers should make it quiter, but who knows. Have you taken it to a exhaust shop and told them your problem.

 

I Have not taken it to an exhaust shop but i will soon and see what they can do
