So I see a lot of cars now with dual exhaust. It used to be a sign of speed, power, performance. I know in theory it should still mean that. But are some car makers using "fake" dual exhausts just to come across as faster? Or is there still something to it? Heck, my Accord V6 has dual exhaust, at least dual exhaust *tips*. The I4's don't. Wonder if it really helps the V6 to breath better and go faster?
Dual exhaust: Does it still mean power and speed?

My Outback has Duel exhaust.
Duel exhaust allows Subaru to run smaller pipes and keep the mufflers smaller for ground clearance.
It's tucked up in there. Not for power in this app.

With the exception of a/the police package and the few real high performance cars, most 'dual exhaust' are either a 'Y' split after the cat. converter or a dual outlet muffler.
Sporty appearance, style, that's all.

Dual exhaust means twice the total at Midas !!

Many cars today are 4 cyls. No need for dual exhaust.
There are a fair amount of V6s, and some good V8s, and a high performance version may have dual exhausts.
Many dual exhausts are not real, there is only one pipe from the front, and then it is split, or the muffler has two outlets.

Both of my 3000GT`s had exhaust that once off of the headers,joined into a single pipe,then branched out into duals.
My 300ZX has true dual exhaust. It has a completely separate pipe that runs from each header all the way to the rear of the car.

As the owner of repair shop doing custom exhaust, I certainly hope people NEVER get tired of the sound,,,that's basically all they get for their money anymore (yes I am upfront if they ask).

When I changed the cat-back system on my Toyota Tacoma, it was not only easy but relativly inexpensive. Total cost of the Borla muffler and the polished stainless steel tip was $110. I used the existing tail pipe, modified to bring the angle of the tip to 45* instead of 90*,extending a little past the body.
I did not do a dual set-up. I used a 2 1/2 inlet-2 1/2 outlet Borla, both centered. The stock tail-pipe is also stainless, with all the shields in place for protecting the spare. All the stock rubber mounting hangers were used. It took me about 2hrs to do the complete job. Sounds great without being too loud.
Alreadygone is right. Sound is wonderful, but any performance gains are imaginary. Making a dual cat-back system would probably lose torque and change the power curve. The only gain in performance would be the weight reduction of removing the stock system.

The only gains in performance are from giving it more throttle to hear the sound

IMO, it is 100% for appearance.
the flow master cat back on my truck sounds really good. thats about all it's really good for though.
I was behind a car that has a fake dual exhaust. I could tell because the clouds of smoke from burning oil were only coming out of one tailpipe.
On a Detroit V8 I like to go with, say, a Flowmaster if the original mufflers are shot. It's an upgrade in sound, and likely the last time you'll need to replace it. I wouldn't bother with a system that still has life in it, but if you need to replace it, might as well go for a mild upgrade.
My car came factory with as many like to say "true" dual exhaust. Gotta love the sound of an american V8. BTW flowmasters suck

I am curious, do you mean that you personally enjoy the sound of your vehicle's V8 engine or do you mean that everyone that has to listen to it enjoys the sound of it?
For numbers from the old days that weren't fudged (much) both BUICK and CHRYSLER stated that the addition of a dual snorkel air cleaner and dual exhaust (this, from about 1969-1973) was worth from 15-25 HP on the V8-455/4v and the V8-440/4v on big cars. This was a stock option. The CHRYSLER had especially good flowing systems with big i.d. and proper sizing along with mufflers that weren't restrictive. Great sound.
What the owner noticed, primarily, was that the car hung on longer in mid and 2/3 throttle situations. For someone who tuned it tightly (rare) it meant the difference between 12 mpg highway and 14 mpg highway (roughly). Or, that acceleration rates didn't drop as fast under sustained conditions (towing).
Now, it's a laugh to see "duals" on a pickemup. A joke, too, for performance as a proper single will do a better job.
