I am getting ready to put headers on. Watson's I think. I have the Haibeck chip and am expecting to have to have it reprogrammed. I have heard I can expect backfiring without cats but that can be programmed out.

So far:
K&N with Open lid
Flowmaster Catback
Haibeck Chip

Once the headers are on (a couple weeks) I'll post the results.
