Installed my cat delete pipes today. Had to replace all four studs coming off the manifolds since Ford booby traps them to strip out if you try to remove the nuts. I managed to cut the H pipe in the correct spots and my mechanic lent me the pipe flaring tool so I could clamp the pipes together properly.
It really woke the car up, I'm now getting a lot of gurgling and backtalk when I let off the throttle.
I love how the mod motor sounds like it's trying to talk while under water.
