(2001-07) Honda CBR600F4i V.A.L.E.™ Slip-On Exhaust Systems: Two Brothers Racing is proud to announce the release of it's new V.A.L.E.™ slip-on exhaust system for the CBR600F4i. Offering greater stability of fitment over our traditional spring mounted systems, our new V.A.L.E.™ system is designed to perform!

Both the standard and high mount slip-on exhaust systems retain the stock O2 sensor (California models only) thus allowing for the unhindered operation of the fuel injection system.

Note: All California model years MUST retain the stock 02 sensor.
Note: ALL models (California and otherwise) from 2006 MUST retain the stock 02 sensor.
You will be asked to provide model year information when you choose a system.

Our M-2 exhaust system features our exclusive Teflon coated, blunted, cast magnesium outlet that not only looks great but also allows for various silencer inserts.

Our P1 PowerTip™ sound suppressor is a recommended accessory for our exhaust systems with M series endcaps. A straight-through sound diffuser, the TBR PowerTip quiets the pipe to about 3-4 dB with no significant reduction in horsepower. Not recommended for use with a spark arrestor screen.

Easy to install - simply unbolt your existing M series endcap, drop in the P1 and reassemble.
