I took my cat out, and I really like the way it sounds. Some say if you get caught without one, they will void the warrenty, not sure if that is the case or not. But, something to check into. Also kinda depends on your dealership. But mine sounds awsome. No problems at all with it either.

remove it keep it for when you need to take your truck to the dealer. Rodslinger can swap his out in like 5 minutes so he says. I wonder if the exhaust is hot or cold when he does this.

If you have a cat delete pipe, one that polts right up with no problems or cutting, REMOVE IT!

If you have a pipe and you want to cut and weld in place, then DO NOT CUT IT.

More power. More mileage. A lil more noise. Screw the enviornment.

Blzrnr,

I just took mine off last week. I'll be towing my trailer about 400 miles this weekend and I'm anxious to see if I get any mileage gains of if it tows better.

Right now its have a stronger diesel small and the turbo whine is louder, but that's all I've noticed so far.

I'll post about whether or not it improves performance. If it does not then I may sell the pipe and put the cat back on due to warranty concerns. I've heard that my local dealers are $hitty about warrany issues

It was hot last time I pulled it back off BC - seriously - I wore gloves.

Pull it - you'll love the sound I assure you. If you cut the bolts on the cat real short like I have and clamp it at the back you can put it on and off in a matter of minutes - literally.

Weren't you saying a few days ago that you actually lost power? I think the turbo spools up faster and I love the sound of the straight pipe. I haven't experienced any better fuel mileage, but it has been downright cold since I installed the exhaust. Warm-up time kills fuel economy.
