All Yamaha YFZ450R and 450X Dasa exhaust systems are handmade here in the USA and the quality really shows with perfect tig welds, trick billet end caps, a billet canister mount, thick head pipe flange and the end caps do unbolt for easy canister repacking.

The Yamaha YFZ450R/X Dasa exhaust system has been proven on the dyno to make big HP throughout the entire power curve.

This is a multi-step, stainless steel exhaust system that includes a head pipe, mid pipe, and an exhaust canister.

Spark Arrestor Included(Classic).

The AMA version is for closed course racing ONLY, a spark arrestor and/or quiet core cannot be installed on this version.

The Classic version is louder at 102db but a spark arrestor and optional quiet core can be added to this version to get the sound down to around 98db. This is the best system where noise is not a concern and you need flexibility in your exhaust setup.

The Shorty version can is 4" shorter than the Classic. It's the loudest Dasa option and comes with all mounts.

Optional Quiet Core is available for the Classic model only and is sold separately.

Optional can colors available. Black is standard. Optional colors may add additional production time.

Optional black anodized end cap and inlet for the Classic/Shorty only.

Optional ceramic coating available to help reduce heat and obtain a stealth black look on the head and mid pipes.
