[QUOTE="Juiced46, post: 1311532, member: 11519"] yes having cats on will make more boost but that doesnt mean its going to make more power then o/r. Say you ported your heads and put LTs on your car. You will make LESS boost but gain power. Boost is just a measure of restriction. I GAINED power going from my catted H to an O/R MRT H pipe. To the comment to the person said someone lost power switching to an O/R X was because they didnt retune for it and went leaner. Thats why he didnt make any more power. My car with the cats on it smells worse then the O/R pipe does. I love the sound to. i just had to put my stock H pipe back on the other day to go to inspection. The car felt like shit. I used to be able to lay into it around 3500 RPMS in 2nd gear and leave a 200 ft strip. i could barely spin the tires in 1st with the cats on. Put the O/R pipe back on last night car feels much better. The TQ and Hp curve do not change. Here is my before and after graph. identical curves. O/R made more power period [img]http://www.mustangmods.com/data/1671/hpipe_large.jpg[/img] [/QUOTE]
