yes I believe it did.
true dual by far
The advantages of having dual exhaust, if it is a true dual exhaust, include increased gas mileage, cooler engine temperature, and more engine horsepower. However, if it is not a true dual exhaust, it doesn't matter how many exhaust ports there are, there will be no advantage.
No it does not because my friend has one with true dual exhaust and it is 5 times more louder and it crackles over 3,000 rpm
true dual exhaust would mean that each pipe would be atached to an exhaust manifold of its own. It might be a v6 or v8 or as in the old days an inline 6 whith a split manifold was popular.
True dual exhaust is better for performance. Most cars on the road nowadays have the "fake" dual exhaust - tips only. They feed via the catalytic converter then after the rear axle - they branch into dual (or Y shaped) thus making the appearance of dual exhaust.
yes you can on eBay too
A cheaper option for dual exhaust without making it a true dual exhaust from the exhaust manifold/headers. Not much performance gained just appearance.
In some case it is just for looks as they are not true dual exhaust systems. In other cases they are for improved performance and are true dual exhaust systems. On most V6 or V8 cars they do improve performance. On a 4 cylinder they do very little to improve performance.
not a true dual exhaust. most cars had two piped that fed into a single catalytic converter, then a single 3 inch pipe out and over the rear axle. some cars had an option of "dual exhaust" where each exhaust manifold fed into its own catalytic converter, then into that same single 3" pipe. some guys have fabricated true dual exhaust systems for these cars....it takes a lot of work to get two pipes over the rear axle and out the back of the car, but it is possible.
about 5 - 10 hp
Really it hardly allows more exhaust throught since it is a dual muffler not a true dual exhaust system. You could block one of the exhaust pippes and your car would still run fine. Most of it was for sellin props like mentioned in the previous answer. to allow more exhaust gas to flow out than a 4 cylinder. and for selling purpose
There is no such thing as too free flowing exhaust on a 4-stroke. But, you can't get true duels on that pickup unless you move the gas tank, since it is in the way. I put cat back dual pipes with no mufflers on mine sounds titties.
