Derbi Variant Autisa Exhaust 3118556 Works better with an aftermarketAutisa exhaust for Derbi Variants with Flat Reed engines. Massive 28mm header. The chamber is 85mm in diameter at the largest section. Long too! Just shy of 40 inches in overall length. Unique grey textured paint. Has two rear mounts so you can use one, the other, or both! Pair this up with the 40mm Autisa kit for a vintage blaster setup. These are from our vintage stash so expect minor blemishes. Very limited stock on these.
