Disco DeCATed
 

Attachment 8083
Not the prettiest of weld jobs (been a while), but it works.

I suspected my old CATs were shot so I cut them out. One actually looked good, but the other was a rattle can of shattered catalyst. I bolted the remaining Y-pipe pieces back on, cut sections of exhaust pipe to length, and tack welded them on. Then I pulled the pipe again and finished welding the seams.

I also removed my rear resonator which made only a little difference in sound, but the deCAT made a bigger difference and it sounds great. No aftermarket exhaust needed.

With all 4 O2 sensors hooked back up and driving for a few days it hasn't popped any codes yet.

I've noticed no change in power, but I haven't tested it either. I drive slow and smooth usually.

Post up a video/audio for us to hear...do it, do it now! ;-)

Are the CATS not required in Oregon?

Of course they are :D, but we have no inspections of any kind here in Josephine county.

man is that rig ever clean underneath and it is a 97 wow

I wish I had the ZERO INSPECTION ZONE.

You deserve it. Did you get a new alternator yet?

I'm pretty sure it has to do with the State of Jefferson mentality here. http://en.wikipedia.org/wiki/Jefferson_(Pacific_state)

Alternator is next on the list. Looking forward to it.

When you step on it (if you ever do) you'll notice a difference........it's starts out with a growl and eventually ends up sounding like a Kia-sewing machine. BUT, it will kick the crap out of a 4.0L J[H]eep from a dead stop. You'll now be able to de-carbon the piston tops with a good jab to the floor.....just watch out your rearview mirror.....hugh gray cloud, they'll be lucky to see what made the fog.

I did the same thing and either Spike drives like an old man or my motor puts out one more pony than his cuz I had to keep backing off while he was following me to the trails......

Yeah, I drive like a old man, I really do.
If I want to go fast I drive the wifes Volvo with a turbo.
