2 into 1 pipes for gs 400 L??

[Anonymous]

i was wondering if any 2 into 1 pipes exist for a 82 GS400L, I'm planning on slapping on a nice sport bike tin can muffler on my bike. Or better yet is there any sport bike type mufflers that will fit my stock pipes without too much modification? I'm ready to cut and weld if i have to.

Check out this UK site. Lots of choices. Didn't see any 2 into 1's specifically for the GS400 there but they have lots of silencers to fit your stock downpipes. I have seen pictures of a GS400 with a 2 into 1 but don't know who made it. A 2 into 1 might interfere with the passenger footpeg if that's an issue and it also might interfere with the lean angle. I would leave it stock and drill some holes in the end for more noise if desired, or put on aftermarket silencers. Be ready to re-jet and rebalance the carbs, though.
