2 cats or one?
Upon looking under my 08 f150, I couldn't help but notice where the exhaust comes together before the muffler. I had a knockoff Flowmaster muffler installed, itso called flowtech. When I looked closers at the system, the pipes come together just before the muffler. Can someone tell me if there are 2 cats, or just one, with my setup? I guess I could have snapped some pics for the discussion, but didn't for now.

Stock 08 5.4 3v has 2 cats

My cobra had 4 cats. A full exhaust (headers, x-pipe, 2 free flow cats, and 3" cat back) gave you 30ish hp AND saved you close to 50lbs. Is there a reason ford seems to over engineer their exhaust system?

I believe an 04 and 05 5.4 3V has 4 cats
