bypass them

looking for first (apart of the header) or secondary (behind the O2 sensor)?

If it's the first, sorry, your only choice is to get from the dealer, or have a new one welded in place. Fabspeed looked at my set-up and determined they could make a custom set of headers with a free-er flowing header design and a higher flowing cat, but it's not cheap. $2000 to modify your existing headers, or $4000 for a completely new set-up.

If you're looking for the secondary cat, don't bother with it, just replace it with a bypass pipe. Still passes emissions (if cat is behind O2 sensor, it's not required), and no check engine light problems. $1400 and weorth every penny for the extra punch low end and better sound!

I have my stock middle cat's available if you want them.
