ok i was wondering if anyone has ever put a glasspack muffler in the I pipe and then after it goes over the axle put a little Y and runs dual tail pipes out the back. If so how does it sound and how easy would it be to do??

 

Sounds like a loudmouth/dynomouth/any other mouth. Guess this would be a glassmouth or a packmouth.

Would sound raspy like any other glasspack exhaust. even worse once it starts to burn out.

Keep in mind that most stick style mufflers decrease in internal diameter 1/4" smaller than the ID/OD. So if you buy a 2.5" ID/OD the flow path diameter inside the muffler will only be 2.25".
