There shouldn't be anything in the pipe itself- but the muffler/silencer will have some type of baffle or snake like pipe inside. Do you know anyone with a gas rig that you can braze with? It's pretty hard to screw up brazing!!!!(that's how they fix expansion chamber damage) and it won't burn through!!It looks like if flip the manifold & you cut the straight portion @ the bend and put it back together you'd get your clearance behind the seat and almost square the pipe up with the frame.- then cut the seam on the muffler end and rotate or re-miter it straight it would go back pretty easily.The muffler don't care which way it points for the exhaust to get out. Sorry but it's hard to know by just pic's!!!!
