    J-Pipe Flaring Problem - Shop flare 1.75 from end - What options can fix this?

    My muffler guy went a bit overboard and flared my j-pipe to 1.75" from the end.

    What's the best option? Cut it off or leave it? What happens if I leave it?

    I dont think thats a huge deal. Its only a 1/4" past where Danny said to stop.

    I know some places can shrink them back down also, kinda just like the way they expand them... at least the guy I go to around here can.

    I was samcking it down with a hammer around the chamfer. Had to watch out for flattening it, but was able to shrink the diameter a bit.

    You're fine, just make sure that the pipe is centered in the hole and proper depth when you mount it...1.5" is what we found to be the SAFE distance, and that includes a built in "fudge factor"....1.75 is about the maximum you can go before waterflow from the 3 holes becomes an issue...Go past 2" and you got waterflow issue...Plus the flow difference from 1.5 to 1.75 was barely measurable...

    Larger holes would not help if it was not at the proper depth...The issue would be the pipe not going down all the way and the flare getting into the opening, which is 2.5" ID...The flare (at 2.25") would then leave less than 1/8th" around the opening, IF it was centered, for water to come down...at around 2" high is the choking point...

    Your exhaust temp sensor will/should sence that its to hot and set off a code and put the ski into limp mode...If not then you will overheat the exhaust and possibly blow out your waterbox....
