Pros: Lightweight, more power, cool look & sound.

Cons: No heat. Harder to confuse with a cat & therefore more likely to get you red-flagged in emissions testing. Also, headers may pass more heat on to the engine, so you may see small increases in operating temperatures when not at speed.

Also, what you've got there just look like a standard set of HEs with the boxes cut off. As a header, they're about as good as it gets. SSIs are, of couse, the best. Bursch ones I hear rust out but may be good for the money. You probably want to just go with the stock size (I believe 1 5/8), anything bigger and you'll kill your low-end torque.

How hot will this engine be?
