Ok so I have a bad catalytic converter on the drivers side.

Any suggestions? I'd like to get the Magnaflow universal 13" cat but from the looks of it, it won't fit primarily because of the turn in the pipe.

Anyone done this cat with success? I REALLY don't want to spend $350 on both cats with the Y.

As always I appreciate any and ALL help.

Its got 115 on the clock.

Before you say anything, I got it for 6K so the mileage wasn't an issue ...... until now of course. :biggrin:

chop em both off, and use the money you would have spent on fixing them on a custom tune.
I would, but:

A. The Auto Hobby Shop on base won't let me do it
B: I have no welding skills
C. I wouldn't know where to begin

I can do pretty much everything else but I have never messed with exhausts.

Just replace w/the stock Y w/cats assuming you have the 4.8, 5.3L



About $350 at Rock Auto

I'm a poor military man. I can't afford such luxuries.... besides $350 can get me a lot of pie.

Also, my muffler is a 2 in one out.

Scoop up a used stock Y, I'm sure someone has one they'd let go cheap.

i have a OBS which is a little different, we have only 1 cat. and i made a universal one work, it lasted about 3 years till it got clogged up or some shit, so i hollowed out the cat and got it tuned out by justin at black bear.
