Removing Cat

I know many of you have removed and/or gutted your cats. Just curious who you get to weld up the straight pipe in its place since it is illegal to remove them on a street car and someone like Midas says ummm no way!

What do you feel you are going to gain by removing the cat?

There is a company who makes a straight pipe that appears (somewhat) to be a cat. I don't have a link, but it seems like it was an FI place that also carried the pipe. You could also do an off-road y-pipe (ORY) to bolt right up.
There are also smaller muffler shops (try finding a mom and pop place) that will do the work if you wish. You will probably want to make it a bolt-in, just in case you want to go back to cats at a later date.
Personally, I don't care why you do it, although little is to be gained by it except for special circumstances.

I just gutted mine and put em right back up there... Looks completely normal, for any mirror inspections that might ensue with the noise... I like the sound of no cats...

Yes. Did it. 97ss with 14psi FI app. Blower pushed rt side cat (core) into the exhaust pipe. I had a Random Y w/ twin 2 1/2" cats. Nice flowing set-up. I removed the Y. Welded 3/4 by 1/8 strip stock on pipe to hold geometry. Then cut out cats. Replaced w// 2 1/2" exhaust pipe sections from Summitracing. Easy w/ MIG welder. I had to install a CCI insert due to noise. Lots of noise. The cats do a good job @ noise reduction. Pipes were less cost than new cats. B.

Dont go to a major auto repair shop. Go to a mom and pop or some hole in the wall place to get it done. Opening up the yellow pages is a good place to start. Just call around till you find someone. That's what I did. Just be prepared for you car to smell after you remove them.

BTW midas never said anything about my missing cats. I guess it just matters who is running the show.
