There no questioning Clear Images Exhaust for loudness. At out Z club dyno meet sat. their system basted all the stillin and borla systems. When you put the trottle down everyone knows this car means business.

 

It's not a true dual, and it's actually only a Y-pipe back. They make it in 2 versions 2.5" and 3" ID piping, $739 and $759, respectively. They are different from NISMO and other single mid-pipe type systems (and really similar to RS*R) in that they don't have a big muffler section. Those 2 eight-inch sections at the tips are all the muffler there is and they are huge and straight-through. Nice design, IMHO.

I have the 3" version and I gained 8-12 RWHP with no other mods.
