2011 Silver Tacoma TRD Express Cab

None

I have a 2011 Expfess Cab model with a 4.0 engine, TRD edition. 121k miles. I going to start towing a competition size bass boat and I'm in need of a new muffler per my local dealer, due to a rust thru area on the factory unit. I'd like to get some better MPG and performance, without sounding like a 60's Muscle car. Any suggestions, also what is the muffler inlet and outlet diameter? If installed by the dealer, they won't be able to do any modifications to the exhisting system !! Thanks in advance.
