That's not really dual exhaust on my 6i, is it? A friend of mine asked me about it the other day. I never noticed the two tips before. As far as either of us was aware, a single exhaust splitting into two tips does not equal dual exhaust. As a reference, I looked uner my dad's old 77 Scottsdale and sure enough there were two pipes running from each side of the V. Is the dual exhaust on the 6i just for looks or is there something I'm missing about the setup? Is the 6s the same setup or are there two pipes being run directly from the engine? I don't really care one way or another. I'm just curious.

almost every car that has "dual" exhaust has a mock dual exhaust. what i mean by that is they have 1 pipe from the headers or intake manifold to a single muffler to 1 or 2 tips(our 6's.) my dakota had true dual exhaust meaning i had headers and dual 2 3/4" straight pipes to dual mufflers with a turndown tip. on a car like the 6 you 1) don't have the room and 2) don't have the need for it.

Only one exhaist on the 6, the dual outlets are just for looks

Thanks for the replies. I didn't think you could dual exhaust a 4 cyl. I guess it looks allright. I bought the car because I got a great deal and it's a fun car to drive. If it looked like a Corolla I'd be just as happy. I just hope the spoiler and the "dual" exhaust will help resale value down the road.

It does make the car look better but I also believe it frees up some of the back pressure because the single pipe is shorter.

Hell I don't know for sure but I think it helps more than a single but less than a true dual.

depends on the engine and pressure you're putting through it. i can promise you that if you somehow managed a true dual on a mazda 6(can only be done to the v6) it wouldn't created more power.

Why wouldnt you be able to have true dual exhaust on a 4 banger? Get a set of split headers and youre good to go.
