The Mufflex systems make great power. IMO, its very hard to find a Y-Pipe setup that will out perform a 3.5" or 4" system. I'm running a custom fabbed 4" system and 4" cutout. Its pretty similar to a mufflex. I could post some pictures, but it wont really point you in any direction for a particular mufflex system. I have never heard any complaints from any Mufflex user. They get great reviews all around.

I have the Mufflex 3.5" System behind the stock manifolds and Y pipe and I did feel a performance gain over my previous 3" system.

The reason behind the single out is less turbulence inside the muffler making the system more efficient and therefore produce better power. And with the tucked up turn down makes for a clean rear appearence.
