Cobra R shorty headers

[na svt]

These came stock on 2000 Cobra Rs are the same as FMS shorties but unlike the FMS shorties, they have very thick 1/2" flanges and also a larger outlet so they will not work with the stock H-pipe; must be 2 1/2".
$250.00

Set these up with a set of high flow cats and a Mac Pro Chamber mid-pipe and you'll be in business!

So that pro chamber will bolt right up to those headers correct? But I will have to lengthen the pipe? Also do you suggest cutting the pipe coming off of the headers and weld the cats in there?

You may have to do some lengthening, give Jeff at Mo's Speed Shop a holler, he did my set up.

What is the size on the outlet on the FMS shorties vs cobra R?
