    98xpl bottom half of pipe overheating

    like the title says, the bottom half of the pipe is getting so hot its melting the rubber coupler. but thats the only part that is overheating. the motor and top half of the pipe are fine. checked the routing of the cooling hoses and they all seem fine. i have never had to two halfs apart. what would cause this?

    Have you swapped the 2 water hoses at the pipe over just above the centre exhaust mount bolt??
    If not The water regulator on the rear exhaust muffler is blocked or not operating properly this is preventing cool water from entering the exhaust stinger and cooling the couplers.

    This should flow water all the time when the engine is running.It just flows alot more at lower revs. And yes the water for the stinger comes all the way back from the exhaust muffler water regulator .

    that was one of the first things i checked. currently i have the line that is coming from the WR going to the top of the pipe. side of the pipe going to the pisser. and main water line going to the bottom. this is correct right? i did run it with the line coming from the WR over the side to see if water came out and it did.

    from the reg to the side by the pipe mount (a 120 jet would be nice) and the top to the pisser.

    You have it around the wrong way. The top fitting goes to the external pisser Y fitting and the side fitting goes to the water regulator.
