Default 2011 dual exhaust setup

Has anyone modified their factory setup? If so, how is the improvement and is it worth the money for the performance.

A cat-back system will definitely improve the flow.

I was hoping for a less expensive alternative. I mean it sounds good now, but with the Volant I have I don't know if it relieving the engine of the extra air flow. It could sound a little more deeper.

Ah I see, well you could always do a muffler swap and put a 14" Mufflex on. I heard those sound pretty good.

I'd go with a muffler swap. This will improve flow with minimal cost.

I put a flowmaster 2 chamber muffler on mine and had the resignators taken off. Sounds awesome and created a more FREE flowing exhaust.
