ok Focus Central Race header and 2.5" magnaflow catback (and FC Flexpipe if applicable)

-vs-

MAC shorty , Focus Central Hi-Flow cat, Focus Central Flex-pipe, Magnaflow

(additional ?) Do you still need a flex pipe with a race header?

I'm more concerned about power vs "legality" since we don't have inspections and stuff, but I'm also concerned about the "smell" is it true once you take out the cat there's a foul smell? and how noticeable is it after you do that? and how "foul" is the smell?

Thanks to anyone who helps!

my car smells like a snowblower since I've put on a raceheader.

Technically you should have a flexpipe to match the increased pipe diameters of your cat back and headers

You would most likely get more hp from the race headers and flex pipe. Although it would probly be louder. As far as the smell it would probly smell worse because the cat filters the exhaust fumes. I don't know about the magnaflow, don't know anyone who has one. I roll quiet with THERMAL EXHAUST.....
