thanks everyone for your input.... Stuart - can you recommend a shop in N.California that i could order through and have the installation done when the time is right? i live in silicon valley (los altos, CA 94022) thanks! Absolutely. I would go and see BR Racing in Los Gatos - one of our authorized dealers and a great bunch of guys. Contact details are listed here: http://www.rsctuning.com/dealers.php

lastly, how would you compare the Larini cats vs. the RSC cats. they appear to be priced about the same, but i'm not sure whether Larini offers a longer warranty than just the 3 years that come with the RSC product.

You should gain across the power band. I was concerned about low-end torque loss from decreased back pressure, but it didn't happen.

The Larini cats have been known to throw codes, but the RSC ones don't in my experience.
