The cans by the mufflers are Helmholtz resonators. There are also two resonators in the X pipe. That exhaust does not have cats in it. It attaches to the factory cats.

ARK Advantages and Features:
- All Bolt-On System
- Helmholtz Design for Minimized Drone
- Burnt Tips
- SUS304 Stainless Steel Construction
- Fully Polished Finish, 2.5 inch Dual Piping
- CNC Machined Flanges
- Exposed Micro TIG Welded

Items Included:
Axle-back Muffler, Mid-pipe, X-flow Y-pipe with resonator, Bolts, Gaskets, Hardware

Some of the resonated hfcs or tps get the hiss down to a manageable level. it's just a sound the motor makes. You'll get more power from hfcs or tps than you will with a cat back, so many people find it worthwhile. It may not be to you if it really bothers you. If you're going turbo later, it's not worth doing anyway. Once the turbo goes on, brand doesn't matter, just diameter. 2.5" will work, but 3" will be more efficient.

You saw it while I was typing. Never mind. Good luck getting it installed. The car is way too quiet stock, so you're going to love being able to hear the motor.

actually I had a question about the turbo and diameter. I hear a lot of chatter about 3in piping, but most of the test setups that companies design their turbos and test on all have 2.5 exhausts. example is the FI turbo. And they also mentioned that using 3in they couldnt achieve proper functionality and performance. why is that? I would automatically assume more flow/less resistance=better performance. and is .5 inch diameter really going to restrict air THAT MUCH. is it the difference between 500 and 550? or are we just talking a few puny ponies?
