exhaust nightmare Clogged Cat?
How bad can a cat back up? Can I fix it with a hacksaw?
So I'm Chugging home from work, minding my own, when my car starts to buck and pop high in 3rd. Some thing had been clanking around near the cat for awhile, (I thought maybe the heat sheild) but now it stopped. I limped it home (5 mi) and then all hell broke loose. The car was bucking again up a hill and this time and the carpet started to smolder above where my cat is mounted. By the time I got home I wasn't finished clearing my lungs when I found a saw and hacked off my cat. Now I'm too afraid to drive it.
Can anything other than a clogged cat cause this problem? I'm thinking a restriction trapped heat and cause the carpet melting. The hot spot was right prior to the cat. Everything else on the car seems A-ok
The car was real hard to start after I cut the cat off, now it still runs like I got a banna in my tail pipe. How can it feel like restricted exhaust with only headers and a y-pipe? When I first built the car in '03 I took it out for a midnight burnout session with no cat-back system and it ran like a raped ape. Any ideas?

A clogged cat will make ALOT of heat. Now that its chopped off...
take it for a spin, make two of these...
...see if it feels any better, and give us a call in the morning.
