Unbolted headers--the aboriginal side exit exhaust.
Dodge Vipers, Shelby Cobras, 1960s AF/X drag cars and NASCARS include them. Of all exhaust configurations outside there, hardly any scream "dynamic" prize side Way out pipes and for pleasant instigation. Exhaust pipes are, for the most object, a essential baneful. Bygone the headers/manifolds, all those pipes can arrange in terms of performance is decrease it. Side Way out exhausts are the bitter end in minimalist example and are affectionate of affection a bicycling garden gnome with a shotgun--short, quite impractical for the street and hot in the fault spot.
Consider the Engine
Side exit exhausts can sound depraved when used on the deserved van, nevertheless Testament cook up most commuter cars sound augmented close a John Deere than a Ferrari. These hot gases are more than capable of melting tires, paint, plastic bodywork and almost anything else it regularly comes into contact with. And remember to use some sort of cover if you're running the pipes along the underside of your doors like the 427 Shelby Cobra and Dodge Viper. Fire makes metal hot and ankle burns are extremely uncomfortable.
Use an X-Pipe
Unless you requirement your V8 to sound prize a four cylinder and your V6 to sound like a Geo Metro, use an X-pipe crossover in the system. A well-engineered X-pipe will not only make a great deal more power than an old-school balance tube (a.k.a. H-pipe), it will help to seamlessly blend the engine cylinder noises into a single, unbroken note. It's simple to engineer, too; just run a pipe diagonally from the passenger-side header to the driver's side exhaust and vice-versa the other end. Use flattened, oval-shaped tubing if ground clearance is an issue.
Exhaust is Really Hot
Many would-be customizers have found out the hard way that using a short exhaust system gives the exhaust gases less time to cool down and a really short one can easily spew foot-long flames under certain circumstances. It's all approximately where you stand. For most cars with a rear Way out exhaust, a listener Testament be subjected to the seamless sound of all cylinders firing in sync. Unless you duct the exhaust so that it all exits over the alike side, an watcher Testament isolated hear half the engine no incident where they stand. Provided you obtain anything smaller than a V8, you might thirst to avoid traditional side Way out pipes.
Down and Back
Angle your exhaust so it points slightly downward and is near the back of your rear-most window. A downward angle will help to reduce soot build-up on your car's paint and the rearward placement will help to keep exhaust gases out of your car when the windows are down. If at any point you smell fuel or start to feel oddly sleepy while idling in traffic, park your death trap and move the pipe exits.
