Top and Bottom mount Manifold
 

Is there a big difference between the two as far as peformance. Currently runnning the bottom mount and looking to do some upgrading as the parts are getting old. Running a gt2871 and looking to go to the 3071 and all vband. Thanks for the help.

I can think of only one thing, and that's the down-pipe issue when you want to keep your A/C.

Using a top-mount will let you have a nice bending pipe going to your exhaust.

Performance wise one isnt any better then the other , use what works for you and how you want to do things , My advise is to keep it simple , simple makes good power as well

agreed, unless you wantto look diferent and custom, nothing wrong with being simple to make easy good power

Top mount ftw :)
