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 has transformed my ZH2.

    Posted by James on Nov 9th 2023

    This has transformed my ZH2, the weight difference from the stock exhaust is noticeable in riding. The sound is incredible it's so good and it has made a difference with the quick shifter, don't know why or how but it has. Finally it looks epic, can't rate this enough if you have a ZH2 with stock exhaust get one you won't be disappointed

    Penta Carbon Slipon

    Posted by Adriano Franca on Oct 10th 2022

    Made my bike sound 1000x better. This slip on made not only the bike sound better at any given RPM's, but switching gears with the quick shifter with this slip on also sounds amazing. I went with the Gloss tip and red logo, and couldn't be happier.

    Penta carbon slipon

    Posted by Peter Cochrane on Nov 25th 2021

    Well this is a great slipon. I went chrome an green badge an tip, this slip on looks great on videos, but looks a 1000 times more impressive in person. High quality ,chrome is deep enough to swim in. I picked brocks because it has acceptable noise level at idle an low revs .but sounds like aF1 car at high RPM.i luv it, easy to fit an took little time. Plus if you want you can interchange back to stock ,as I do on nite shift.

    Single Penta-Carbon Slip-on System

    Posted by Julien V on Nov 17th 2020

    The system was shipped promptly. The Slip on looks very good and was easy to install. It eliminated the back pressure the OEM exhaust created at gear shift. I can now hear the auto rev matching! The motorcycle is a lot more stable in turns since it lost all the weight on the right side and it run s a lot smoother. Over all a great buy and I would absolutely recommend it for enhanced performance, great looks and smoother ride.
