Did you type the rest of your post in invisible ink?

Why yes Ill add details now.
2007 Mazda6 3.0 Im interested in deleting the Cats as Im in Mississippi and theres no smog issues at all. I've heard about running straight pipes from the exhaust manifold and needing to know how to do it without throwing a code and making the "Check Engine" light stay on.

Unless you get an ecu tune that's a stupid idea.

The stock exhaust system on the 3.0 is smouldering trash with these weird bends in the piping, sounds alright though, get a nice custom cat back made for you with the second cat removed, resonator and high flow muffler. At a local muffler shop. Unless your car is an auto. .

 

[socalinhouse]

Its a Automatic. Seems like a bunch of flow restrictions I see your point now that you mention it. Thanks for your input.

I had a 2004 GT 5-door 3.0 and I got a CP-E MAFCI system... which was a CAI and a piggy-back tuner. That was pretty good for an NA Mazda IIRC... it felt like 250-260 hp instead of 220. Can't recall if I had exhaust. I have CP-E exhaust on my MS6, but I corked it with a muffler.
