The NEW Brock’s Performance Penta-Carbon™ Stainless Steel Exhaust System is like no other. Make it your own! The Penta-Carbon™ is designed to be customized to your specifications. The heart of this customization is a beautiful five-sided carbon fiber endcap produced exclusively for Brock’s Performance by world-renowned carbon composite specialists Blackstone Tek (aka BST Carbon Fiber wheels). Not only is the carbon cap available in gloss or matte finishes, we have also expanded the offerings to match any available BST carbon fiber wheel custom ink colors, for a combination that is truly unique. Check this link for more information on Xirallic®, the shimmering ‘Ink’ finish applied to produce subtle colors that explode in direct sunlight: BST Custom Ink & Finish Options

Don’t have carbon fiber wheels yet? No problem, the colored end caps match the schemes of most brands: blue, red, and green… just to name a few.

‘What about the pipe,’ you ask? With sharp lines to match the aesthetic design trends of most modern sportbikes combined with the aggressive sound (hidden noise suppressor sold separately) Brock’s exhausts are known for, the Penta-Carbon™ shape won’t get lost in the crowd. They are available in show polished stainless or black ceramic coated stainless. If you like the sound and power of our Alien Head mufflers, you will love this modern take on Brock’s legendary mindset.

As an added bonus for our #stupidfast friends, the Penta-Carbon™ muffler is also around 1/2 lb. (.22 kg) lighter than a comparable Alien Head or ShortMeg mufflers and outflows our Slash Cut mufflers.

And finally, the Penta-Carbon™ Mufflers are adorned with our new, more discrete, logo plates in a variety of colors as well as in our Stupid Fast (US Trademark No. 4,268,627) version: Logo Plate Color Options

    This exhaust slip-on sounds amazing. Super Loud at cold start letting your neighbors know your about to rip the streets. Once the bike is up to temp and rmp's settle, the tone is amazing through the entire rev range. The drone is a bit loud however mixed with wind noise and helmet you hardly notice. This is the best slip-on you could fit to an H2 line of bikes.

    Penta-Carbon Slip-On

    Posted by Danny Jackson on Mar 10th 2022

    The Penta-Carbon slip-on from Brock’s sounds great and was very easy to install. The new slip-on looks good on my ZH2. It was nice to get rid of that OEM can. I am very pleased with this system.

    Slip on

    Posted by Ben on Aug 22nd 2020

    Fitted like a glove and as Brock says not an offensive sound but when you give it some throttle it sounds awesome. Delay in delivery by USPS but covid and politics i don't blane them. Made it to Australia perfect condition in 3weeks and then took another week as our postal service is crap. Let me know whem the full system and ECU hack is out

    Sounds great

    Posted by Derrick on Aug 10th 2020

    Not incredibly loud at around 3 RPMs. But when you open the throttle you will turn some heads.. I definitely noticed a better throttle response. I installed it in less than 7 Minutes very easy.

    I love it! It flows so well with aesthetic of the Z H2, now it finally sounds so good and it’s really light weight. It’s easy to assemble, put on and just like Brock said in the only took minutes.
