I'm thinking of putting aftermarket headers and mufflers on my 3.6 997 cpe. Should I anticipate any problems with the computer with the header install. Will the ECU read the different flow characteristics and anticipate possible lean conditions. Also any warranty problems?
Any experience with this situation. I'll be using FabSpeed products.

TIA

Have AWE headers, low flow cats and EVO intake-no issues, no CEL's. I'd check out AWE-the headers are perfection-ported/ground to match heads etc....send me a private message and I'll email some pics. Haven't dynoed yet but in the works.
