If you have a V-6 or larger, you will also notice a significant increase in horsepower. If each bank has its own exhaust system, there is more space for more exhaust to exit the engine. For example, if your vehicle has eight cylinders and a single exhaust, all the used air is trying to get out one pipe, one catalytic converter and one muffler.
This can cause back pressure — like a bottleneck traffic jam — thus robbing your vehicle of horsepower. Adding a second exhaust system so that each head and exhaust manifold has its own system allows double the exhaust to be forced out of the engine, thus increasing horsepower. Dual exhaust also decreases some of the back pressure that is common with single exhaust systems.
Another back pressure builder is the stock exhaust manifolds. Because of the way they are designed, they tend to increase back pressure. When you convert to dual exhaust, be sure to replace the manifolds with headers.
Choose headers that are stainless steel to reduce rust. Also, if possible, choose headers that are made so the pipe lengths are as close to the same length as possible. Increased Gas Mileage: The engine in a dual exhaust vehicle runs more efficiently and with less effort.
The more efficient the engine, the slower the rate at which the fuel burns, which means that you don't have to use as much fuel as you would with a single exhaust system to go the same distance. Your vehicle may have a single or dual exhaust system. If your vehicle has a single exhaust , the pipe coming out of each manifold is jointed in a Y before the catalytic converter and muffler.
A single exhaust has one of each while a dual exhaust has two of each. If the exhaust is leaking, the most logical thing to do is fix it. Invest in a New Muffler. One of the most important parts of a car exhaust for keeping it quiet is a muffler. DIY Soundproof Mufflers. Buy a Silencer.
Put in a DIY Silencer. Other Tips for a Quieter Car. A straight pipe , for example, can cause exhaust gas velocity to increase. This will likely reduce engine performance below 2, or 2, RPM, making your vehicle a little slower to launch from a stoplight. The biggest reason that many people opt for a straight pipe exhaust is that these systems enhance your car's horsepower.
You get better fuel economy and slightly better horsepower. However, the size of the pipe is important. You can't just go and get a thick pipe for your car. The optimal exhaust size is a function of exhaust volume. The greater the exhaust volume, the greater the optimal exhaust size. Post by cv67 » Mon Aug 26, pm.

Hence a search for a quieter but nice sounding system. Post by farmer » Sat Jun 26, pm One thing we have to remember, which I myself soo griefly almost forgot is that there is actually many times NO NEED of the huge tubing you see around town!.
The only thing these are good for is to "look cool" and try to scare your opponent on the strip. While I am trying to learn my way through header building right now, I have tried sevral different types of muffler setups, like Greg refers to.
That does NOT make me an expert, let me make that clear. That means up to approx. AS this is being talked about as fast street cars, we can leave the weekend warrior type of exhaust out, but we can still learn from them. Greg is on the right track by thinking two different types of mufflers for the fast street type of engine. But be a little carefull to mix the brands too much. Sometimes it may "backfire" on you and work - well not so good.
Lets assume that Gregs engine is a with a peak power about rpms. Exhaust is hot when it leaves the header, and you need a scavenging effect to keep things cooking. Then go under the tranny, like BAS style and fumes chill a littlebit, now use a Magnaflow type of muffler. This way you get a hairswith colder exhaust going though the second muffler, hence less resistance eventhough it is an expansion type muffler. If you like it to bark when you hit the pedal, use a straight through model instead.
The next thing to take into consideration is, that most engines of this type needs a little back pressure in the exhaust to make a decent torque curve, and fuel curve for that matter.
As itn is "only" going to be an approx.
