Well my 00'ws6 had the SLP LTs with 3"y pipe and cats already put on. Im not a big fan because the exhaust is sitting so low i cant afford to lower the car.

If i could afford new headers they would be mid length..

Pacesetter is the best bang for the buck. get the ceramic coated LT's and ORY and you will be fine...

When looking at the car from the side you can see the exhaust sitting about 2 inches lower that the body... There is a mildly steep driveway i pull into for work, and at the apex of the drive i have less that 3/4" clearance...

450 check out speedinc.com they have some pacesetters for 374 and Hookers 399 there is so many to chose from but I ordered Hookers Headers which are a good set of headers LTs which I would recommend than the shorties.

no no no, the obx doesnt have cats, those are resonators (empty tubes that look like cats in the hopes of reducing rasp/passing a visual inspection). they will still throw codes and youll fail a computer disgnostic inspection.

Go with Longtubes and don't look back.

However, if you are planning on keeping your LM2, prepare for it to be pretty damn loud
