Just to explain it a little better and make the story longer lol!....the GHL has straight rods welded on at the exact places that you push through the exhaust hangers...everything fits great. Except that...these rods are slippery and straight...no hook at the end or a seat type thing for the rubber exhaust hanger to stay in place. So with a little fun driving, vibration and going over terrible roads like up here in Montreal, the axle back would always move 1-2" towards the driver side and hit the lateral links I believe. If you add passengers in the rear it would be even worst. I felt like an idiot, at the end of every ride, I would get out and kick the exhaust tip to move it back into place. I forgot to check for a few days once and the exhaust tip melted on my rear lip...so pissed!
So fed up with this, went to a local exhaust shop...got it all centered and then the guy welded these washers on the rods, tight against both sides of the hangers..problem solved, no more sliding, no more rattles. The only thing is, if I decide to remove the exhaust, I'll need to cut off the exhaust hangers...so basically I'm never removing this thing.
BTW, I used the Kartboy exhaust hangers...not sure if I had kept the oem hangers, if it would slide as much.
