Looking for clues...

I had a Pintara wagon years ago, (4cyl, 8 plug motor), and had to replace the rear muffler, which was a dual tip. When I was looking for the cheapest replacement option (car wasn't worth spending money on) I was told that being a wagon, it had the dual tip to reduce cabin noise from the exhaust.
I got this from a couple of places, while I was getting quotes. |

as drawn :- left would be balanced, ie the pulses would flow better helping to draw out some of the exhaust gas if the pipe was tuned correctly (the exact lenght req.) But the most important thing though is still the diameter of the pipe..
The right side concept with a balance pipe fitted offers less restriction in comparisin as the LH system is not 'tuned' and the velocity of the exhaust gas slows as it is travelling alot further. I guess it comes down to hours and hours on the dyno to find the most effective and space permitting system for an individual car. I made a set of custom pipes for a 454BB One tonner a few years ago and the owner gave me a few pages of information ( inc. some crazy rocket science mathematics) to work from.. I can't remember the science of it all now and lost the info years ago

I agree that dual exhaust like the pic on the left is just a waste and I would say more a **** factor, but if done like the right pic then it can be justified.

The Mazda 6's run 2 separate mufflers on opposite sides of the car at the back, but surely a full twin system would be overkill on a 2.3L 4cyl. They must run a single to the rear axle or something, seems like a lot of extra expense for very little gain, doesn't even look that good.

I'm pretty sure I am correct but I think the reason they do it is to asertain maxium exhaust flow/power and to remain quiet. You can only flow so much out of a quiet single system.
Noise regulations are getting tighter too. So the manufactures have to get creative.

/me thinks its sad that Twin System (tm) on a late model car is usually a little Rice-Box (tm) and most of the big V8 cars "only" have one single outlet on one side.
Long live the '70s (tm)! :disco:

agreed Phycho chicken.
350Z Maxima with the VG V6 runs the same system but single into twin after the rear wheels they are 180KW stock and give a Ba a very good run for their money STOCK. both accord EURO and 'SEPPO versions in V6' run the twin system, euro has 140kw from a stock 2.4L 4 cyl thats more than a 3.9L EA had and almost what the EB had in a much ligher vehicle which has one of THE best chassies comming out of japan in a car that supprisingly seats 5 comfortably. Mazda 6. Would you pick on an MPS?? i think not unless you had an XRT or something simmilar, even the stock 2.4L will do the qtr in 16.2/16.0 they arnt a slouch for a 4 cyl and twin pipes make for a balanced look at the rear. Liberty's on the base 2.0L they dont 2.5 GT and 3.0L they do, once again nice balanced look and GT and 3.0L have balls... i still dont understand what your on about? yes the XRT/ esp XR8/GT/Pursuit would suit twin pipe system as seen on the monaro but i dont think that twins on a car is a bad thing, and there are alot of cars on the market that deserve alot more respect than what they currently receive.

Exactly, try telling me a Spec B Liberty or GT doesn't have balls. Might be under 200kw but they are friggin fast.

I'm not trying to bag any of them out at all. Just stating what I thought. My GF's parents have a Mazda 6 and it's a bloody nice bit of gear, I just wondered why a dual exhaust would be necessary on a 2.3L 4cyl, but obviously they are, and if you are spending $35k on a mid size car.....why the hell not have a dual exhaust! :P

Probably a similar reason to the suby, they can put two smaller mufflers in rather than one large one with wasted space.

dumpy at the back for me!... regardless if done tastefully, for purely asthetic purposes the look good, as does everything! Performance is a different story and open to a completely different argument..
