Barrel Decat Pipe for Triumph Street Triple and Daytona 675

The Decat Pipe for Triumph Street Triple and Daytona 675 is a plumbing part, not a muffler. It replaces the restrictive catalytic section ahead of your silencer. On the Triumph Street Triple and Daytona 675 it is the piece that decides how freely everything downstream can flow.

Fitted on its own it opens up the midrange and sharpens throttle response. Paired with a Barrel canister it is what lets that canister actually do its job, rather than being choked by a restriction further up the system.

Build

• Stainless steel 304 throughout, so it will not rust through a monsoon
• Supplied with mounting clamps
• Covered by Barrel's warranty
