13BREW Exhaust Port Block-Off Plates

Cap it off. Keep it sealed.

The 13BREW Exhaust Port Block-Off Plates are designed to seal your exhaust ports when your engine is in storage, on display, or waiting on a build. No more open ports collecting rust, moisture, or shop debris while your motor sits.

Why you need them:

Exhaust ports are especially vulnerable during storage. Moisture buildup leads to rust, and rust leads to problems you don't want to deal with when it's time to fire things up. These plates give you a proper seal — clean, secure, and purpose-built for the job.

Features:

• Direct fitment over exhaust ports
• Keeps out moisture, dust, debris, and pests
• Clean finished appearance for display or storage builds
• Simple bolt-on install — no modifications needed

Stop stuffing rags in your exhaust ports and hoping for the best. Whether your engine is sitting on a stand, tucked in a corner of the shop, or mid-build waiting on parts — the 13BREW Exhaust Port Block-Off Plates keep things sealed and protected until you're ready to go.

These plates are currently made to order as we build up inventory. Please allow 1–2 weeks for production — we'll always do our best to get your order out as fast as possible.
