Fresh air injected into the exhaust system on modified sportbikes can cause back pressure in the headpipes and muffler due to unburnt fuel from modified fuel mapping combined with additional oxygen spontaneously combusting in a high heat environment. Our blockoff plates will stop the annoying and possibly damaging back pressure from occurring while allowing you to remove a few pounds in associated valves and hoses fromyour bike. On late model EFI bikes with 02 sensors, ESPECIALLY when using Dynojet's Power Commander V with the Autotune feature, the air injection system MUST be blocked as it will introduce additional oxygen into the system which will skew your 02 sensor's values and make it impossible to get a correct tune.
Features:
- Driven Racing's emissions system block-o plates allow you to eliminate fresh air injection into your exhaust system with a simple to install, attractive package.
- Available for all late model sportbikes.
- Machined from 6061 Billet aluminum and then anodized black
- Kit comes complete with a cap for airbox.
- Note: Images shown are generic, each kit is designed according to spec for the application.
- Made in the USA

Fantastic Product
Thanks to the install video I was able to complete the project with no hiccup.

A definite must is you have an ECU flash
These are the ones to get, DRIVEN products are the best. The guys at STG can hook you up and get you going fast in no time!

Installation
Installing these plates was very easy on my 2017 YZF-R1. They were basically free since I got $30 in bonus cash from SBTG for purchasing a M4 Y-pipe catalytic converter eliminator. Back-firing has significantly been reduced even though ECU has not been re-flashed from stock.

Fast delivery, Easy install, Great product
Block off plates were at my door in a few days. Install was a breeze and they work exactly like they're supposed to.

Another great product.
Nothing to special about this item. I only wish they would put together a better set of instructions that goes with the motorcycle that you own. The build quality is great.

Nicely Machined Fit Great
These are nicely made CNC style and fit great on my 15 R1. I'd recommend them for anyone looking for block off plates to go along with their tune.
-
Perfect fit
They fit perfect and I would recommend them to anyone looking to help save time or headache of the stock parts. I wasn't looking for weight savings or performance.
