Welcome to SUPER Single Lineup of RK systems for the GR Toyota Supra!

 

Just as the name implies, the SUPER Single system is the end all, flow all, sound all, JDM all, and weigh LESS than any system in its category and even other categories!

The offerings of the Track Edition and Signature single and dual exits have been undoubtedly some of the best for the platform.  We set out last year to develop the SUPER singles for many of the popular platforms we make parts for.  These systems are not for everyone.  They are for flow and function.  If you are browsing the forums or facebook pages and are asking questions about drone or whether the center brace fit, this system is not for you!  These are not questions that you even care about for your build.  You're instead the one that wants that Chef's Kiss protruding the rear valance of your MK5.  That undoubtedly iconic 4" glory sound that only RK will give!

How does it sound compared to your other offerings?

Simple. Different. Deep. 

It's louder than the Signature but quieter than the Track.  

Will this fit an oem outlet downpipe?  Will this fit my 2.0?

YES!  We carried over the same exact fitment design as our other Supra offerings.  We can adapt any size downpipe from the 2.0 to 3.0. Oem outlet size to 5" outlets size!

Let's talk weights!

The SUPER Single weighs a staggering 12.5 pounds!  That includes hardware and hangers!  The RK 3.5" Signature system weighs 11.8 pounds!  The Track is 9.5 pounds!  Our next closest competitor is 13.8 pounds and it's a 3.5" system!

 

What makes this system SUPER?

-True 4" CP Grade construction 

-True hand made by RK in house in the USA (Tacoma, WA)

-More JDM angle on the rear section

-Increased tip size to 4.5" to fill the opening

-Optional 5" tip size

-Increased muffler size to give the iconic deep throaty sound and JDM look

-The straightest possible routing

-Staggering weight of 12.5lbs making it the lightest true 4" system and lighter than every competitors 3.5" systems!

-Signature coloring and Laser engraved muffler and tip

-Lifetime warranty to purchaser against defects

 

If that wasn't enough to compel you, then the pictures and video will!

 

All systems are made to order! Standard lead times will apply based on our order queue.  

*Minor trimming of the rear bumper is required

*Removal of the underbrace is required

These are hand made to order. There are no cancellations after the order is placed and no returns.

Nice shirts for the price! But do not recommend for thick body types.
I bought 3 different ones. 2 Mediums and 1 2XL. The mediums fit correct and really nice! Would definitely recommend for the price! More like a exercise material, and sticks to your body shape... Sooo the 2Xl did not fit the person correct. Was so tight... And the strech is to stick to your body... So would not recommend for anyone a bit hefty or fit tbh. But the shirts are good materials and feel nice for a fresh day out or to use as gym clothes!!

Great Value heat gear material with high neck collar and loose fitting
Color: Black, Size: X-Large
My husband has been looking for mock neck shirts that are comparable to UA heat gear material but that are short sleeve and fit loose to wear under his work uniform. These seemed to have been a good soft quality option and the price is is great.

This shirt is so soft and the color is as depicted. Great mock turtle. Size is as expected. Ordered a large- 5’9 165# It fits well maybe a bit long but I wanted it loose.
