rh essentially can mean many things..

In this definition, RH means Race Header, an exhaust manifold and is illegal to use on US Public Highways and Roads because of the elimination of a Catalytic Converter, which causes green house gas emissions to enter the atmosphere and cause Global Warming. ..But who cares? :)

This is an item apart of a car's exhaust manifold. This piece is found on cars with Subaru boxer engines. It is appx a 1 foot exhaust pipe that is between the header and the turbo. On regular wrx's, the uppipe has a cat within, but on the STi model, it is catless.

That part of the exhaust manifold system, on older vehicles, known as the heat riser and necessary to aid in fuel evaporation and make the transition from cold to hot idle engine operation efficiently.

A type of duct burner installed aft of the exhaust manifold, but before the turbocharger in the exhaust gas path of a turbocharged internal combustion engine. Produces gas flow which provides for turbocharger spinup during periods of low engine load

To have your car's engine run with the exhaust manifold bare, rendering it obnoxiously loud, according to rice boy standards.

Your general stock cars are by itself equipped with these items, that guide, muffle, and clean exhaust gases, as well as reduce performance by increasing backpressure:

Exhaust Manifold - A sturdy structure that covers the exit paths after your exhaust gases has left when the exhaust valve opens. It purpose is to collect exhaust gases so it can be either pumped with air to burn undercombusted hydrocarbons (provides no power, but better smog tests) via air injection, or further send down the tailpipe, where further methods are undertaken to quiet and clean the expanding exhaust gases.

Tailpipe - Narrow metal tube, that not only directs the exhaust gases to the back of the car (or to the sides), but because of its small diameter, slows the flow of gases, quieting the motor significantly (an a explosion for example is basically a loud expansion of gases). Slant eyed rice enthusiasts would take the hint, and install gigantic

movie that was made by retards, for retards. why the heck in the beginning is there an exhaust manifold pressure build-up? its pretty much a tube going to the back of the car, how would there be pressure problems? i could see boost failure off of the turbo... MAYBE. and when it does fail, why does the floor fall out? firs the manifold is in the engine compartment, second, the floor is one big stamped piece of steel, there is no reason for it to be bolted on...

and nobody would take a supra like that to fix up. its a toyota and thus there are many, why waste your time with a rusted out pos?

tells you that any car is faster with T3h NaWs Yo!!!

thanks fast and the furious for raising a bunch of retards that think a jetta, 240sx, or supra could kill ferraris

this is something you say when your friend or aquaintence has either done or said something funny or has been own3d by someone and you want to rub it in. It can also be used to express surprise or admiration of a colleague or friend.

It is short for awww nigga and can be used instead of nigga if it is deemed too offensive a word.
