I have an 06' LR3 V6. I've put some extra weight on it, and want a little extra Hp to offset the mods. I am having hell trying to find performance parts for the V6. Any sources?

Also, would putting racing cats on the exhaust completely **** off the computer and give me an eternal engine light, or is this something do-able?

Thanks for any advice/ ideas.

 

The V6 is the same engine used in the Ford Exploerer, so check Ford parts.
No hi-flow cats should not cause any problems.
