Has anyone done this? I know theres the Greddy SP2 Axle back and some people have swapped out their stock muffler for a Flowmaster...but how about making a single exit exhaust with a HKS CF/Ti Muffler and some custom piping while still using the stock mid-section? Anybody done it or seen it before?

 

theres tons of guys that have done the HKS Cf/Ti mufflers to a single outlet but i think most of them had it custom built y-pipe, mid and rear section.
