I installed mine, I also installed a bunch of other stuff at the sametime so I can't say if I notice anything, I picked it up cheap and Iimagine it has to do something. ( hopefully more then just add dead weight to the car )

 

GET the CHE brace with torque limiters..its a must have...no question..its really great...

 

does it work with long tube headers?

 

Yes i believe it does..depends on the make..read about it on another stang site.. with MF initials..

 

Does not work with SLP long tubes.
