I had a local shop build my Y-Pipe for my LT headers..I have scraped then on a few speed bumps and stuff and noe the pipe is touching my frame and with the car in gear and foot on the break it vibrates pretty bad and as realy lound inside the car.
I tryed wraping some leather around it but that just made it worse.. any ideas of what i can do besides take it to the shop?

 

My Mufflex(SUX) was hitting on the bolt that holds the little clip that holds the furl lines up to the frame. I jus ttook it off and used a large socket, turned sideways, and just made a real little dimple to clear the bolt head. I dont think the small dimple is making a difference in flow. I still turned 293hp to the wheels.

 

I had the same problem with the ASM headers and i installed Poly motor mounts to fix it. They raised the motor about 1/2" and gave me the clearance i needed.

Lower the trans mount will angle the pipes down away from the frame.

 

how do i go about lowering the trans mount? add some washers?

 

Why not spend $20 and have a muffler shop weld in a hanger and hold it wherever it's banging. Solves the problem

 

Sounds good to me...thanks i dont know why i didnt think of that
