Not really, im looking for a catless system. The pipe that comes off the header has cats, i want one with no cats. Its not gonna pass emissions, but then again iv never had a car that does.

for example, on my mustang......

midpipe with cats:

still nothing? I cant seem to find anything. I might just end up cutting them out and putting a piece of pipe in those spots.

One issue you might run into is a lack of backpressure that will cause you to loose power. When I removed my cats from my 1996 4.6L Mustang GT is lost power especially in the low end! I got 2 high flow cats and it came alive again!

And not to mention I had to fool the computer with MIL eliminators to keep the
check engine light off and avoid the "limp home mode"

But I am sure you know that since you have a pony too....

Be forewarned the Jeep computer is VERY PICKY! And you can kiss the lifetime warranty goodbye too...

Why don't you just get Hi-Flow Cats, they'll do the job, and will take care of your computer, which will go just crazy if you put a "test pipe" aka "Cat Bypass pipe".

I don't understand the term "high flow cats". Ain't no such animal. Converters have to have backpressure to generate the 600 + degree heat they need to operate. If it has backpressure, it ain't high flow.

They make them for CJs, YJs, TJs and just about every other off road and race vehicle. A set of MILs will solve the check engine light. My warranty is already voided, and i didnt have the lifetime anyway. They wont void your entire warranty for an exhaust system anyway.

I have had 3 stangs and an srt 4, i had a catless pipe on all of them and never had a problem. I know many many people that go with catless pipes and love it and never have a problem.

I have seen high flow cats throw codes and fail emissions tests, plus they cost way too much and you dont get the same sound as a catless pipe.
