    tsp y pipe fell apart!

    so I finish up my header nd y pipe install the other day and within 100ft one of the pipes blew off. The Kit fit great but with the solid pipes there's no way for the band clamps to crush down enough to actually hold on. I used a cutoff wheel to cut notches in it and its perfect now. Is this a memo I missed or what?

    You have to tighten the snot out of band clamps. I think the ones I used called for around 75 lb.ft. of torque.

    I use the band clamps that are a uniform diameter all the way through, so when you clamp them down the clamp actually forms itself around the step in the piping. Fit nice and tight and have never had an issue with them for many years.

    Some other band clamps come with a step already formed into the clamp. I've found those to not be so forgiving and need to be cranked really tight. Even then sometimes the pipes may twist around a bit so I tend to avoid this style of band clamp.

    Yep I had to really tighten mine also. Almost 7 years ago! No issues, but I saw this post and checked it out bc my ORY was cracking where it joins, had to put some reinforcing weld on that whole section. Now it's golden. I thought maybe pk had an issue like that.

    I used the clamps that came with our Kooks LT's and Y and haven't had any issues. They do drip water from the joints on cold startup.

    You need the good ones that are about $12 a piece and made of stainless. They hold time and time again, and the pipes easily slide apart when you need them to. The local Napa where I live is the only place that sells the good ones. All the other stores have the cheap stuff.

    Don't buy the cheap $8 versions, you'll have nothing but problems.

    I got tire of the band clamps so I welded mine. Only have clamps at the collector meets the y and one more under the passenger rear seat. It will soon be replaces with a cut out tube.

    Yeah, I generally weld all my systems where I can get away with it, and use the band clamps where the system needs to come apart.

    Someone got the bright idea of welding the entire system on my wifes car, and when it came time to remove it for a fuel pump swap, I had to pull it all off in one piece. Luckily I had the rearend out of the car at that time anyway, but I sure as hell didn't put that system back in there. I bought a new setup, welded it intelligently , and left certain areas removable with band clamps so I don't go through that mess again

    I know how you feel. I'm changing the setup on my wifes camaro yet again, and I just put the 4" mufflex on there a few months ago. I've had 5 different systems on my chevelle over a 27 year span, and I just put a 3rd system on my firebird over a 20 year span. Had 3 on my truck before I was finally happy and I'll be making a first attempt on my other truck. I'm such a picky SOB It just never ends around here
