Chapter 11: Exhaust systems


Without reinventing the wheel, here we will simply cover some common riceboy "performance mods" instead of discussing the physics of an exhaust system.

Riceboy likes to act like he has dual exhaust when in fact the motor could never officially support it. The dual exhaust term is coined from the fact that a manifold and header can come off of each side of a "V" block. So, any motor with a "V" can have dual exhaust: V6, V8, V10, V12. 4 cylinder and some 6 cylinder vehicles are what is called an "Inline" motor. These are easy to identify by just looking under the hood of a vehicle. If you see spark plugs and wires on each side of the block, this means it is a "V" style motor. If they are all located on one side, it's an inline motor. There are very few exceptions to this, as some motors have two spark plugs per cylinder (we think Ford did this for some of their 2.3L motors for example) and the spark plugs enter on either side of the head.

Riceboys with inline motors pretend like they have dual exhaust. Typically what is done is they have an aftermarket exhaust system installed, then they just run a "T" off of the last foot or two of pipe and run the pipe to the other side. This visually looks like dual exhaust, but does not at all perform like a true dual exhaust setup. If a ricer tells you he or she has dual exhaust, take a peak underneath to see if they know what they are talking about. Or if you know what motor they have in their vehicle, call them on their error. They probably won't know what you're talking about anyway. Here are a few examples:

1.   Dodge neons have inline motors. This vehicle appears to have dual exhaust. Riceboy fails once again in the performance category.
