We've been running two indy 550 SS as chase sleds when we ice fish. They have treated us well and our easy to maintain, provided we can find parts! We just noticed a pinhole leak in the exhaust of one of the sleds as we were going through them for the season. Obviously there's little to nothing online as far as full exhausts go for this sled, at least from what we could find. Looking for the groups recommendations to see if there is any aftermarket product, or another location we could look for OEM ones.
