But that’s not all ~

All RK systems are modular by design

So what does that mean?

They are interchangeable!

You currently have the Signature drivers exit now and want the dual exit Signature?
No problem! 

Order the Signature dual rear section and swap it in! Reuse and save some money on your current front pipes as all proceeding RK systems for this platform will use those!

What else did we do with the dual?

You now can customize the rear section with any of our coloring variants! Please keep in mind, all front and midpipes are only shipped in raw uncolored as with all of our systems!

Helmholtz carry over to this system!

Well what is that?

A Helmholtz resonator is a specifically designed size, length and shape of tubing that acts as a noise canceller for specific sounds and frequencies when fine tuning an exhaust. We specifically targeted the ‘drone’ at highway cruising speeds and rpm’s between 60-75 mph.

So what does that mean exactly, did you get rid of any drone?

Simply put, our Helmholtz design reduces the amount of drone or in cabin resonance created by a free flowing exhaust system in these specific cars. This does not however mean it will work with XYZ companies downpipe or catless turbo elbow or zyw companies bigger turbo. The calculations we used are targeted for stock or mildly modded cars. It is not a one size-fits-all 8 lb muffler thrown at the midpipe of the exhaust system in hopes it worked. It will not affect the overall sound of the car but only adds .9 of a pound!
