It's a BumbleBee!

Well, after doing the head job and valve replacement on my 1998 Metro 1.0L the CEL came back on and I had a catylist code in the system. I got to thinking because my EGR ports were dirty, but not plugged and I lost compression in #1 cylinder and not in #3 which is common for the EGR. I also noticed my fuel mileage got better, but not what I expected from the car.

I got a bug up my butt and decided to chop out the cat. I found all the guts inside were melted down and the cat was plugged. I patched in a piece of pipe and took it for a ride..................... :lol2:

This little car had a major boost in power and right when the RPM's hit the "sweet spot" the sound coming out of the tailpipe sounds like a pissed off bumblebee! Now to upgrade the entire exhaust.

Don't go too big, you'll lose torque which is what this car needs most. Two inch crush bent is the absolute maximum, probably too much.

I was thinking of going 2" all the way to a nice, restrictive, quiet muffler and no cat.

When I bought my 1.0 L '93 Metro used three years ago, it had no CAT -
came from Montana.

It does that pissed off Hornet sound at a specific RPM - I asked about it on this
Forum and never got a really good answer.

Probably has to do with the "Resonator" that these babies are supposed to
have in the exhaust line of pipes.

I get 49 mpg in the hot part of summer.

If I move back to the City (Spokane), I will be required to have the Cat put
back in...DAMN!
