Just got back from the exhaust shop. 2.5" pipes and 40 series Delta flow Flowmasters. What a freakin differance from the rams horns and 1 3/4 pipes. Took off like I normaly do and it broke the tires loose and went sideways. Pretty cool except I was not even expecting it. And that is with 33's and 3.08's. I expected to gain a little power but was not expecting that. The neighbors are unhappy with me now, wait till they get a load of this HA. Damn that rig sounds cool.
