    After LT and ORY install question

    Got my headers on last night with a ory. Question is, has anyone gotten bad vibrations at idle? If im at a red light, "in drive" on the break, it vibrates like a mutha. The driver side y pipe is touching the floor board, so i think i can get some of that rubber stuff and put between so it might stop. That all i can think of that would be causing it. Any suggestions>?

    Thanks

    i would also like to no how the bump stop is, i have less then 1/4 in between car and y pipe, do i need one? i have vibrations like crazy,but dont really feel it under my feet. my cat back is hitting in like 3 places. two places just off the y pipe and then over the axle. drives me nuts

    Its not so much that you can feel it but im sure you can hear it, normaly the Y pipe hits right under the driverside floor pan. The stock pipe had a flat spot to prevent this but aftermarket pipes dont have enough clearence. The bump stop is worth a shot but I recommend cutting out about 12" of the pipe where its hitting and weld in a new pipe that has a slight bend in it.
    Its your call though...
    Heres a link to the bump stop.
    Its about 3/4 way down the page...

    Yes some y pipes are flattened to prevent the rattle. If you remember what the stock Y looks like it looks like it got run over its that flat. Your exhaust guy tucked it too close to the floor. the drivers y needs approx 3/4 + of an inch to not rattle. I had this same issue and went back to my exhaust guy many times. he repeatedly heated the top of the pipe and smashed it flatter. it still rattled a bit. I bought an exhaust hangar that helps stop the rattle from hawks thirdgen parts or something... let me find the link.


    here it is:

    Definitely helped alot I only now get a rattle at wot above 5000 rpm in first if the road isnt smooth. otherwise no rattle

    I have the opposite problem. My y is already on the floor, so it doesn't bang, its constantly vibrates. And my header is doing it too. What is the thing called where i can mallet a piece of rubber between the spots so it wont vibrate.

    I think he means hanging to the floor as in its raised so high its touching the floorpan.

    If its that high I know your problem. The guy who put the system on is an idiot. Get the exhaust cut and welded with sufficient clearance.

    The original OP said he got them put on "last night". Guessing he installed himself.

    The pain problem is that the S.S. headers are different brand then the Y pipe. Beleave me, me and 2 buddies did the best we could to get the y and cat back to get on with no leaks. The driver side is touching the floor, and the passenger isn't. Like i was saying, whats the rubber block piece called so i can mallet a piece between the y and the floor.

    Stainless Steel Option Racing Long tubes, and Pacesetter Y. Many people on ls1tech and here have had great results with this combo. I guess i can always bang away and grind some stuff..

    if you plan on having your car for a while id try to avoid that..... thats just me tho, try some other options first to see if the sound goes away.....ive heard of guys banging in the floor boards and shit, to me that ruins the car
