E55 Header questions.
My 05 just came off warranty, thinking about doing a few mods. Came across a few headers. Anyone have any experience with these?

I've got a pair of EC LT's for sale that will gain 30+hp over those shorty headers. Those might get you 20hp at the wheels. Maaaaybe. Probably closer to 10-15. Theyre not doing much to fix the bottleneck.
