Looking for a new exhaust header - F-Body Road Racing and Autocross Forums

I would like to request a little help and experience in selecting new headers that tuck up nicely under the car. The current headers from SLP have been on the car for about 10 years and for the most part were decent except for they hung low. And dragged on everything that was 3 inches or taller in the road. Now Fast forward to June 2014, just got my tired Bilstein ASN shocks re-valved for stiffer springs and installed. Now with the height adjusters at max height the header is approximately 2.1 inches from the ground when measured. Definitely way too low for street driving. From where I jack the frame up I have 5 inches of clearance.

Any undercar photos that shows a well built system would be great.

Requisites are:
Stainless steel; full length headers; no bigger than 1.75 primaries; Y-pipe diameter smaller than 3 inch if possible, 2.5 inch would be great and then merge to 3 inch factory axle back exhaust.

A well engineered set of headers and Y-pipe that closely hug the floor pan shouldn't be a problem, should it?

I hope these photos show

Ken Kurtz & Alan Blaine, If its not too much too ask, how low is this car (Ken's car) to the ground from the front jack point? Those headers seem to tuck up quite well to the body, who makes them? https://flic.kr/p/aryD7m https://flic.kr/p/9HVqd8
