Hi I have a 1998 dodge ram 1500 sport 5.9L 4x4 automatic and I really want to remove my cat just to make it louder and I don't want to do it if its gonna mess up my gas or back pressure? Now I dont know if it will or not? This is what I need help on. I know opinions go either way but I really just wanna cut it off and put a pipe in it's place. Tell me if it could benefit or help me. Or if I do, do this what cheap improvements I can do to make it run like a champ after removal. Please stay on subject, thank you.

 

You can get a offroad y pipe from jegs to go in its place and it'll actually help you out a bit as long as you don't have to worry about inspections. There's a list of stuff you can do after just depends on how deep your wallet is.

 

you can go with a high flow cat... they are louder...I had a gutted cat I just replaced with a magnaflow and the sound difference is almost unnoticable... if you want the mean sound get headers..they can be had for almost the same cost as a new cat.

 

So what bad things will happen or what good things will happen if I just replace it with a pipe? I'm going the cheap way. Already cut the muffler and put a pipe in it's place. I just need to know the exact problems I might have? Backpressure and gas are ones I hear of. But most people say it hasn't happened to them when they cut their cat out.

 

mileage, always going to run rich, and maybe a cel because of the o2

 

Bad? Nothing really. Maybe a rear O2 code if you don't do the non-fouler trick. (DIY in faq section.) Not exactly emissions legal.....

Good? Better flowing exhaust equals better breathing for the engine equals a bit more power. Especially if the cat is partially clogged.

 

So what if I cut it out? Leave the o2 sensors in the pipe?

 

Put the non-foulers on the rear O2. Will work fine.

 

whats a non fouler and where can i get one?

 

I think they mean to use a spark plug non fouler on the o2 . most auto parts stores have them.
