Get rid of the popping when switching to an aftermarket exhaust on your DR-Z with the Goheen Cycles DR-Z 400 PAIR Valve Delete Kit. This all-in-one package replaces the bulky secondary air injection system with precision CNC-machined block-off plates, allowing for a cleaner engine and a more refined exhaust note.

Why Upgrade?
Stop the Pop: Eliminates annoying exhaust popping and backfiring on deceleration, especially with aftermarket exhausts.
Accurate Tuning: Removes "false air" from the exhaust stream to ensure true Air/Fuel (A/F) ratio readings for precise fuel mapping.
Cleaner Build: Frees up engine space by removing the entire Pair system.

Kit Includes:
PAIR Valve block off plate
PAIR Valve plate gasket
