Really? A pair of high flow CAT pipes and headers for $500? Show me where I can get them!!! And I'd like to hear from those experienced, specifically with 2.5L motor. I got stock header/ CAT plus PSE, wondering further improvement.

The price went up since I posted about them. If you email them he will give you a better price. I still haven't bought them yet, I'm too worried about breaking the manifold bolts off in the block. You can find headers for $150 all over the place.
