OK so just wondering if all mugen twin loop axle backs have the mugen engraved on the tip ? Also do they have to have the jasma stamp on bottom? Because I'm looking to buy one that only has the mugen stamp on bottom of canister but doesn't have the mugen on the tip or the jasma stamp on canister any info would be appreciated

 

Anybody?

 

pretty sure they do, it will say mugen on each side of the muffler tip, at least assuming it is the same as the catback
