3" large rear muffler options
 

I'm not all that happy with my rear muffler on the GT. What options are there that are a larger muffler (like the stock one) with dual outlets, and a 3" inlet at the front of the muffler. (Not on the sides.

I know Perrin do one, but the NZD/USD rate will mean its going to be $2k, which is cray. But it does look the business.

Greddy Supreme SP looks alright, but only 2.5" inlet :(

Any others I'm missing?

Look at x-force
