I had a set of OBX headers installed and the passenger side collective area is rubbing the frame. The driver side is close, but has room. The engine is shift as far left as it can be shifted. I do have the polypro engine mounts installed, so the movement is minimized. However, when you turn the car on, there is definitely rubbing going on.

What options do I have to move the pipes so they don't rub?

 

Mine were also close like yours but remember the torque of the engine lifts the passenger side and lowers the drivers side. So I move mine a tad off center to the drivers side and never had anymore problem. Next option is to use a flat pry bar were it is touching and put pressure against the frame rail causing a small flattened area on the header. It won't hurt anything at all.

 

Thanks. With it being shift as far left as it can be, I'll try the pry bar. I thought of that but wanted to check around first for fear of damaging something.

 

I had the same rubbing after my Mac longtube install. After shifting the eninge a little to the driver side problem solved..

 

mine on the passenger side isnt so bad, but when i try to make a hard right turn i rub on the steering shaft. maybe lowered motor mounts would get me away from there lol.

 

*cut/remove the 2 attachments on the trans support (metal bars on the H-pipe) , you DONT need them, as stated in muscle mustang.
and other mustangs outlets, they were also the cause of SOME rattling issues. until you do this NOTHING is gonna move and stay-put , it will only slide RIGHT back.
* the way to create a half-inch more space, squeeze that H-PIPE connection INWARD (use a come-along tool), theres atleast an inch or more space. THAT will move the collector inward AWAY from the frame.

 

Thanks that might help. It only rubs when I first turn it on. As it warms up some, the rubbing stops (or is minimal).

 

My 1 3/4" Kooks were hitting the passanger frame rail in the engine bay and I had to shift the engine and the K-member over towards the driver's side for clearance.
