I just wanted to know what is the difference between the Mac Prochamber and the Mac Hpipe?? Is one louder? Does one flow better? Both would be o/r pipes.

 

I just thought of one more thing, do I absolutely need a torque wrench or is it possible to do without?? Also sorry I asked soo many times but no one has answered,do I have to go to ford for that exhaust gasket or can I get it at my local parts store?

 

make sure to install it piece by piece dont put it together then istall it it would be a pain
