Description
We present to you the Track Edition single exit exhaust system for the GRC!
100% hand made in the USA ?? using CP grade titanium. Each unit is tig welded and back purged.
This system is a straight through true 3” connecting at the factory midpipe and terminating out an RK twin 3.5” center exit tips.
RK has spent countless hours designing, driving, testing, re designing, driving, testing, listening, weighing and lastly welding this system to get it just, right.
We think you will agree.
Where did they end up?
Lightest possible weights at just over 6 pounds complete with all hardware.
Optimized sound bringing a clean, deep, pure natural vibrant tone out of your GRC with the straight piped growl!
What about your tuned Helmholtz resonator option on the Track Edition?
The Track Edition is a straight piped system. The addition of any type of resonator designed to reduce drone has proven ineffective and counterproductive to the benefits of an ultra light weight system.
Want a rear diffuser on your GRC for added benefits of aero and downforce?
RK teamed up with Verus Engineering and designed our systems to easily clear their offerings. (Picture gallery for reference)
But that’s not all!
Every RK system is a modular system by design!
Want that extra growl but don’t want to buy a whole new exhaust? Want to change it up for your track day this next weekend?
Every RK rear section will swap in with your RK front pipes. Simply swap out your Signature muffler or Track rear section. Swap in a driver exit muffler or Track setup and completely change the look and feel of your car!
An option only RK does!
Are they your one-exhaust-fits-all?
RK listens to the request and they build the parts!
