ive done a few things sence last time, anywho question is i have longtubes now and a catted H, will i really see that much of a difference if i swap out for a catless midpipe before i hit the dyno or is it not really worth my effort

not sure what all you have done, but you are not going to see much difference between the catted and off road midpipe. you biggest difference is going to be the sound. save you money and research another mod to add some power: cai, catback, pulleys, intake w/ tb, flywheel w/ clutch, driveshaft, gears, tires. like i said i don't know what else you have done to your car, so suggestions are up in the air.

The difference between a high flow catted pipe and an offroad is like 1hp. MAYBE 2..if i'm not mistaken. Like stated sound will be different though.
