Cattman Exhaust System
Hey Guys,
Last night my Mechanic and I was installing a Full Cattman exhaust system y-pipe to the cat back muffler. We are having problems with the install going smoothly. Does anyone have this setup and has pics of the finishing product? If so can you please post them? We seem to be having problems with the exhaust system rubbing in some areas. We get rubbing around the cross suspension supports located under the resonator. We are getting rubbing around the heat shield where the muffler pipe passes the fuel tank. It seems as though the muffler with the mounts installed lays crooked so it rubs on the rear bumper too.
Please help.
Thanks

1. Remove the cross brace or use some washers to make it lower in order to give yourself more clearance.
2. Get stiffer rubber hangers or some hose clamps to add stiffness to the OEM muffler hangers. I've posted pictures in other threads before, so look around for those, or just go to page 6 of my homepage.

I emailed Brian about this issue and his suggest turned out to be the fix all. I didnt believe it but it was like night and day. He said that we should check the resenator to see if turning it around could be the reason why everything is out of place. After twisting the resenator the whole damn exhaust system layed into place PFM! That knocked my mech. and I off our feet. Nice trick Brian, LOL! Now we just have to get this O2 sim to work right.

don't the wires have to be extended on the cattman ypipe on the 2k2-2k3? I dunno I saw it somewhere on maximadave's website and he extended the wires...dunno exactly which one, but he did it...anybody chime in?

If you have a CEL, its for something else and not your y-pipe installation, unless something was damaged during the install.

I had to lengthen the wires on my Cali-spec, but it is very easy and I've never gotten a CEL.

BUT for the 02-03s, there is no pre-cat in the stock y-pipe and both pre-cats are between the manifolds and each bank of the y-pipe, so an aftermarket y-pipe does not replace/remove either of them.

And here I thought I knew everything.
It always bugged me that I still had one precat with my Cattman Y. I dont even think I would bother buying one if it didnt get rid of any precats.
Oh well, hopefully I will be able to get my Cattman G2's this summer... I hate having to wait to mod.
