Ok, here's the deal, I don't want to go back to an o/r h or x-pipe setup because of the exhaust smell, but since I have my stock h-pipe back on, I was wondering how much louder the exhaust would be if I cut the 2 rear cats off. Any idea?

not to much louder if you still have the other cats still on there.

Do yourself a favor and save up for a catted x-pipe. If you want to know how it sounds, watch the vid in my sig. I have a magnaflow catted x and CB system. Honestly I don't think it's even worth the trouble to do what you're talking about. You won't get much of power or sound gain out of it.

dude just leave the stock H alone and get yourself a catted mid-pipe or if you have the O/R pipe with you buy two cats for it and weld them on

Do not chop your stock H. You may need it someday and you won't like the pricetag for a new one.

Your efforts may seem like a good idea, but many people have done this and later regretted it. Save for the proper equipment in order to be satisfied.

A catted H or X will suit you quite fine.

Correct me if I'm wrong, if you cut off 2 cats you will still get the same exhaust smell?

Thanks for all your help guys. I've gone the o/r x-pipe route before, loved the sound, but didn't like the exhausty smell everyday

I cut all four of my cats off..I think the smell is something you will have to live with if you want to go with a off road mid pipe..

I wouldn't chop up your stock H either.. you'd probably end up with more problems then you started with.

The smell isn't so bad, I barely notice it now days. If I stand behind the car while it's on and then turn it off and go somewhere I can still smell it on my clothes or whatever, but the people I'm with usually don't mind or notice lol

I think that's what really bothered me the most, when I got to work or the mall, movies, etc and got out of my car you could smell exhaust on me, and I didn't want to smell something like that at a dinner table

But other than that, I loved the sound the o/r x-pipe made with my flowmasters, now I just want a little more noise than the stock h-pipe gives with them. It sounds too boring now

My old truck had 2 of the cats removed and the pre cats were gutted. It had a smell. Whether you cut the stock H or use an o/r X pipe it is going to smell. IMO

But if I don't cut the rear cats or keep the pre cats, wouldn't that keep the smell away, like a catted mid pipe? Just asking
