Exhaust Alternative expansion chambers

[Spare_Parts]

I have seen a bunch of dirt bike expansion chambers fitted to the CG engines. Thought a thread dedicated to that subject would be a good idea. If you have something please post make, model, year and some pictures. If it is someone else's bike please give them credit.

Bianchi sells a header kit to use "99%" of dirt bike mufflers on the HT motors, but they charge $50 which seems a bit steep to me.

At that point, I would spend the few bucks more and get a bolt-on pipe and not have to weld lol.

I would make that setup myself. No need for all that.
