true dual by far
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.
To allow better air flow for my 383 Stroker......
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.
Dual exhaust systems are systems in cars that have two mufflers and two exhaust pipes. This system is called a dual exhaust system, or a twin exhaust system. It can be installed on a vehicle after market.
Auto parts retailers can usually order those kits for you if they don't have them in stock. FALSE jeep Cherokees can have a single side exhaust ordered from any parts dealers if you want a dual exhaust your going to need to go to a exhaust shop and have them custom fab you one. nobody makes one as a kit i have a flowmaster exhaust, with dual pipes out the back. My buddy made this from the cat back, sounds GREAT... :)
by having a exhaust shop weld on a y pipe then just run the dual pipes out the back
dual exhaust
Dual exhaust systems increase capacity of the exhaust system and thus makes it easier for exhaust gasses to exit the combustion chamber. This can result in increased horsepower. However, dual exhaust is often used because the owner prefers a more "throaty" sound.
Performance exhausts are usually custom bent and made by most exhaust shops.I have a 1987 olds cutlass and have used the Iroc Z design from the converter back .the muffler is an 80 series Flowmaster .It sounds really nice and it definitely helps the performance.Check in the yellow pages for people who custom bend their exhaust. As far as dual exhaust goes , the flowmaster is a single in and dual out sytle which keeps me emissions legal and gives the appearance of duals as well as the sound also.
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.
Yes! Then you would have triple exhaust.
I have a 1976 F100 and yes I put Dual Exhaust on the truck and it is great!!
