i drive a s70 turbo im wondering if i cut off the stock muffler AKA suitcase from under my car lol. and replace it with a glass pack muffler how will that sound i want a nice sound any ideas on how this will sound ??

 

Not from me.

 

LETS HEAR IT!! ha

 

I want to do the same thing, a glass pack basically is a pipe that has fiberglass packed on the inside, hence the name "Glass Pack". It reduces some noise and allows greater flow. It would sound throatier for sure and allow alot more exhaust flow, i just have one question. Where does back pressure come into play and do glass pack pipes do okay with a turbo, Do they provide enough back pressure?
