Hi,

the car has h22 turbo Avid mounts 3" pipe with very quite custom exhaust ,
From outside the car is very quite but from inside it sound like you sitting on the engine and the muffler is inside your hear at 1-1.2K rpm the car has vibration, more and lower then this there is no vibration.

Any idea how to make it quite from inside?

Thanks

 

1. you have h22 in a delsol/eg chassis with im guessing avid solid mounts.
2. 3' exhaust system
your gonna have to deal with it.

 

you mean that there is nothing i can do to make it quite?

 

drop the origal engine back in it
you have to deal with somethings when you wanna go faster

 

no problem for me to deal with it, although it is not fun if i make it DD.

just thought maybe you have an idea on how to make it less loud.

 

well im assuming you have atleast a muffler at the end? if thats all you have, try locating a long resinator to place mid way through your system. It may tone down the cabin sound...i typcally run resinator and muffler in my 3 inch systems...its still loud but what do you expect? you have an h22 turbo.
