Hi All;

2.0 Mazda6 is of single exhaust.
2.3 Mazda6 is of dual exhaust.

Can anyone advice on how to change single exhaust to dual exhaust?
Can i use the 2.3 Exhaust system onto the 2.0 mazda6?
Is 2.3 and 2.0 Exhaust pipes of same diameter?
Finally my current idea is to get Mazdaspeed sport muffer for Mazda6,
follow by getting the Y-pipe of 2.3 mazda 6. Maybe a cat of 2.3 is also need to perform
a bolt and nut fitting. (No welding please)

Guy can advice?

If you want the dual exhaust - buy the 2.3. The car will be more expensive if you perform this yourself rather than buy it the way you want it in the first place.

The procedure itself wouldn't be too hard, though, since there is no difference in body.

But one more thing to consider is that the dual exhaust system is VERY expensive. We're talking som 1300 US$ here...

The price difference from 2.0 to 2.3 is so small that it doesn't make it possible to add very much stuff to the 2.0 before it gets even more expensive than the 2.3. And then what was the purpose of getting the 2.0?:sarc

Hi,

My advice is similar to Steve's, purchasing the 2.3 litre Model might save you alot of hassles....

Or perhaps go to aftermarket Exhaust Specialist, and let them do the hard work, they could Contact your Mazda Dealership & determine whether the exhaust system from 2.3 litre engine model can be placed on your 2.0 litre engine model...............

It will no doubt cost you a fair bit of money & may involve welding.......

Cheers
Rod

Errr.....

My 2.0 M6 is around US$55000. Dunno how much for the 2.3.
Not yet launch in Singapore.

I thinking:

Original pipe + 2.3 cat + 2.3 Y pipe + mazda speed muffer.

Wat u think?

I think it could cost you around S$3,000 to modify it. If you're interested, i'll try to find out for you.

Nice to know another Singaporean in the forum.

The 2.0 and 2.3 are four cylindars, no? Then a dual exhaust is not a true dual exhaust - do you really want to spend all that extra $$ for that?

A true dual exhaust requires a "v" engine - with each single coming off each side of the "v".

That's right, Applejax. The dual exhaust comes from a Y connection right behind the rear axle. To me that is technically pointless, but it sure looks sporty...:D

I see no reason why it shouldn't. But there is always the risk that you may have to change the entire exhaust system. And before you order make sure that the engine isn't damaged by the different exhaust system.

If you're looking for performance increase by adding a dual muffler to your car, you'd be mistaken. Unless/until you fit a high-flow cat or change your extractors to 4-2-2 (4 outlets, 2 going to each pipe means 2 catalytic converters); you wouldn't gain very much in terms of performance.

I don't know exactly which posting had talks about how the pipes go in 2.3... It was said there correctly, there is only one pipe in real, dividing for two (just for fun and the looks in away).

Since I had the situation I took some pics of it:

Look at the end of the car (left); there the pipe devindes into two.



And here is where it all starts (lots more wires at the bottom of a car than I ever thought there is):
