Hello everyone. I'm new here and I just bought a 96 gt. The car's only mods that I knew of were a flowmaster cat-back and k&n CAI. However, I noticed that my car seemed a little bit louder than most stangs with cat-backs. When I looked under my car to check the mid-pipe I saw that it was a stock mid-pipe however the last 2 cats on each side had been deleted and replaced with piping. I'm also confused as to why the car has not brought up a code for this. The only code so far has been for the evaporation system whcih still needs to be fixed. I know the stock h-pipe comes with 6 cats on it all together. However I was told that the first two smaller ones on each side are actually called pre-cats and are more of a resonator. I was just wondering because although the previous owner cut out the 4 rear cats he left the front two small pre-cats. are these pre-cats actual converters or just resonators? I live in NJ which has strict emission laws so if my car has no real converters ill need to purchase some for inspection. Thanks in advance for any help given. :thumb:

I think our pipes have 2 cats and 2 resonators...so I would say the previous owner cut out the resonators. Welcome to the site, how do you like the stang...is it ur 1st?

I love my stang. It's my first but I've wanted one for a long time now. The thing was I used to ride/race motocross a lot and needed a truck to put my bike in. I have a 98 f-150 and it's a great truck but part of me really still wanted a mustang so I finally sucked it up and decided to finance a used one. I came across a 96 laser red gt with 117k on it. I got it for 4k with a 6 month warranty so I feel that I got a decent deal. It's a great car but it could use a little more in the power department. Hopefully in the future I'll do a full p.i. swap and go from there but for now I love it. Thank you for your help and you have a great looking mustang. :thumb:

I've had my 4 cats cut off for about 1 1/2 years now and have only had the 2 pre-cats... It has never tripped my CEL and I never used a tuner or put mil's in. I think you should be fine.

Welcome. We have emission laws here in germany, too, they check the emissions every two years. I'm curious if they'll notice from the emissions that a cat is missing.

BTW that EVAP code is easy and cheap to fix. :)
