Has anyone changed their muffler on an ELXR811 as a performance based modification?
Muffler has 2 pipes in and 2 pipes out.
V8wagon is checking for me, thought maybe someone else has already done it, why reinvent the wheel!

Yeah got mine done with the rest of the exhaust / headers. Since it's a dual system, the stock one was replaced with 2 x Lukey straight throughs..
