Ya guys I'm just debating and long tubes would be next but still figuring what to do as far as cats and he said he would cut them off but that it wouldn't be right. And apparently just 2 cats isn't enough back pressure and I would loose low end power. But the regear is prolly why you didn't knotice any loss

I wouldnt get too caught up in this whole back pressure thing. Plenty of guys on here cut cats and run straight pipes or use mufflers and have no problems with low end power. Do your exhaust for sound because performance gains are going to very minimal between each exhaust set up.

Yeah the only way you would probably notice loss is on a dyno. But if your running big tires on stock gears it will get annoying! (Always straining, hardly ever luggin in O/D) What motor/gears/tires do you have? Also, make sure you get your O2 sensor situation in order!

For sure ill post pics and I had this Idea but don't know if its overkill or what. I had seen a truck that did and exhaust out to the back and instead of having one tip exit to the rear of each tire he did 2 on each side and it looked badass. I just don't know whether or not I would on mine what do you guys think??
