Are there no cats on out H pipe? I thought we had 2 sets of cats, on after header and one on the H pipe. But i only have cats right after the header. Is this right? I swear this looks like aftermarket pipes. But i want to make sure cause i know the 05+ already has large pipes.

Stock exhaust only has the cats after the headers - so total of two near the front.

Ok thanks, man this thing is going to be loud as hell in a few minutes when i bolt these SLP LM1's on.

Kill the cats and make some noise. I thought my new exhaust was loud to start with, but its grown on me now. The stock H pipe seems to be a bad design, if one of your cats go bad you'd have to replace the whole mid pipe. I know I've already done that with aftermarket parts, but if you went back to Ford for it you'd have to pay large.

Ive got flows on mine and I installed the H pipe a few days ago. It sure is loud. lol

I've got the non-cat H-pipe with everything else stock and it sounds awesome, loud enough to sound bad *** but not annoying at all and easy on the ears for normal driving.
