Cat bypass for 97-99?

[blinkwatt]

Anyone know if they are made? I noticed Fabspeed sells them for the 2000+ not for the 2.5L.

If I recall correctly, the 2.5L models don't have a secondary set of cats, just a hum drum set of primary cats. Our secondary cat bypass pipes come standard.

Yup. I wish we came with half cats though, lol. Just a resonator and muffler would be fine with me, maybe not even that.

So would these eliminate the Cats on a 97-99 2.5L?

I think those pipes would bypass the 97-99 cat.


From my understanding the o2 sensor after the cats would set off the cel, if the cats where not there anymore.
