is there an advantage to having more than one exhaust pipe on your car?

Question

Does the size matter? Or does how many you have matter?

Answer 1

On a stock production car; not really. If you're building a car for racing and taking away the catalytic converters and mufflers then it's definitely better because it allows more exhaust flow which reduces engine backpressure.

Answer 2

The real reason, why cars have dual exhausts, is because the engine is not mounted horizontally, or the engine has to two camshafts meaning it's a v6 v8 v12. another reason is because it's rear wheel drive why the engine is vertical. like let's say the Corvette. Rear wheel V8, make sense? it'd lose a lot of power if it was a single pipe. because both sides of that engine is throwing out exhausts. two manifolds. On some cars like let's say the S2000 i4cylinder is mainly looks because it only has one exhaust manifold. it is a nesscity on some motors because they way they are mounted, and postitioned. Some use it for looks. Think about it makes sense. Adding a bigger exhaust increases air flow, but remember you also need back pressure, so if it's too big, you'll actually lose some power. a big exhaust mostly requires the use of Forced induction, to actually make use of that extra airflow coming in and out.

Basically if you're looking to throw on a dual exhaust on a car that doesn't come with it, especially on a single exhaust manifold then it is just pointless and stupid. there's a reasons why things are the way they are on a automobile. =)

Answer 3

If it's a V8 yes. If it's a putt putt four banger it's just plain stupid. Size matters depending on how big the engine is and how much power it has. Going to big is just a bad as being to small. Two is more than enough. Unless there is little room for true dual exhaust. Than one bigger pipe might work better.

Answer 4

Usually larger diameter exhaust pipes means it's easier to get exhaust out of the engine. Dual exhaust systems are often more efficient for the same reason. Some back pressure is required, but usually bigger is better.

Answer 5

More horsepower, better air flow. The more horsepower, the bigger the size, but I'm talking racing stuff. Size of the exhaust on a regular car is stock, don't change it. Whatever your car has, is what it should have. If you're thinking of adding another one to a stock car, good luck!

Dual exhaust is usually on the higher performance cars. I'm partial to Corvettes :)

Answer 6

There is both style and also power involved in two tail pipe systems, especially in high powered vehicles. Using two tail pipe will allow the waste exhaust gases to flow out freely making the combustion to be more powerful and giving comparitively high horsepower...NMN

Answer 7

the better your car breathes, both in and out , the better it will perform, that is why dual exhaust , two sets of pipes from the engine all the way to the tailpipe, works better...

Answer 8

running two exhausts is best if you have two manifolds, but just for single you could increase diamater and add a high flow muffler only! towards the rear of the car. and chrome always looks nice, good luck

Answer 9

better air flow which in turn creates more power and better sound, the diamiter will also play a critical role in the power and sound. smaller pipe will create more back preasure and a louder "crackling sound" and a larger diamiter will have a deeper more mellow sound, or course i am talking about a V-8 though

Answer 10

size and amount matters best for the looks, but i aint too sure if power or anything changes (im not saying it doesnt though)
