Vibration under my feet from the Y pipe I installed Pacesetter long tube with pacestter ORY and I have a crazy vibration going on under my feet from the Y pipe vibrating on the bottom how do I rid it???
sandwich in a piece of radiator hose between the pipe and the floor board. Did you bolt the pipe down by the little tab? If you did just saw it off and do the radiator hose mod 
When I had a y-pipe the same thing happened to me. The y-pipe doesn't have enough clearence. Try taking the y-pipe off and put a board or something between that spot and the y-pipe tighten everything down and then remove the board, should give you some more clearence. And you could also do some banging on the floorboard there with a hammer, just watch be careful of the lines running across there 
And if you had this done at a shop, well . . . take it back to them and complain!

Great suggestions. My pacesetters are doing the same thing when I take off hard and the engine torques over. Won't the radiator hose melt? If so, is there any other high temp rubber type substance I can wedge between the y-pipe and the floor?

Verdad Gallardo If your worried about the hose do like I did.....screw it the floorboard. This way its only in contact when the engine torques. Mines been like this for a year now with no signs of melting.
Mine hits the floorboard under high torque/low speed with my pacesetters. I've often wondered if hard launches at the track with ET Streets could break header bolts or damage the headers. However I can't find evidence of that ever happening.

not just any motor mount.... Polyurethane motor mounts is what you mean and they are a complete pain in the *** to put in. Try a search and you'll see. Plus, someone said that after a his mounts got a chance to break-in the ORY started banging again. Its so much easier to just put some rubber hose in. www.thunderracing.com has a nifty hanger made by Mufflex I believe, specifically to go on ORY to eliminate the banging but is is around 40 dlls if I'm not mistaken.
Ha, yes that is what I meant I have a poly tranny mount, def. better than my stock one. It eliminated the bang from the cat back system on my car as well as the transmission hitting the floor obviously

i just got my headers done and I am definately getting some banging under the floorboard,
does anybody have any pictures of where this Mufflex hanger go on the Ypipe, where is it mounting to on the car's frame?

The radiator hose, won't melt. I took a lighter to mine and tried to burn for about five minutes, and nothing happened. Have had radiator hose on since december, with no effect on it at all. I would try that first before spending $40 on the mufflex thing, jmo.

Correct. I run 30* of advance and it kicks back to 26-28 on launch.
