open header Mug

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 fart cans to their tailpipes to turn their tranquil hum of their civics into a vomit-inducing whine. Like they even need it anyways. Muffler - As it's name states, it further "muffles" the sound of the still rapidly traveling exhaust gases by forcing it through a series of small intricate pipes. Catalytic Converters - Helps burn excess uncombusted hydrocarbons that have unfortunately had not be burned up after introducing air into the exhaust manifolds (temperature still hot enough to ignite raw fuel), via air injectors operated by a air pump. Also, it helps get rid of Oxides of Nitrogen (Unuseable, unlike Nitrous Oxide), and changes carbon monoxide into less lethal, carbon dioxide. Catalytic converters reduce performance and sound just as much as mufflers, though if overworked (if your car has rich-fuel problems), it would glow and strain, melting the honeycomb like structures inside, further clogging the path in which exhaust can escape. A obstructed path for exhaust gases to escape is very bad for engine performance, if nearly completed plugged, exhaust gases have nowhere to go but back into the combustion chamber, causing the motor to run terribly, or stall. The idea of running your car, preferably a hot rod open header, is to increase performance, lessen the strain on the engine, make it sound louder and more macho, as well as to impress your friends. Unless your attending a open header contest with other like gearheads, removing any of the above components is ILLEGAL as stated by the DMV. But at least this definition gives you something about exhaust and performance.

My balls are so wet now that I have bought this item. The nut in my butt is boiling

I've had this mug for over a year now and every single day it watches while I shower. It makes me safe sometimes protects me from the voices. Other times I'm lying on the couch watching judge Judy and eating my hot pickles and the mug becomes angry I feel it approaching me with menacing aura. Next thing I know I'm pooing out pieces of ceramic. Overall, its a great mug but only if you can afford multiple colonoscopy's and extremely invasive anal procedures a year. If you have the money for that THIS IS THE MUG FOR YOU.

This mug has given me a new meaning to wake up everyday. I absolutely adore it and I don’t think my life would be the same if this mug did not exist. A gift from God, truly.

My daughter is a Seinfeld afficianato. She was pleasantly surprised when she opened the package with her Penske File mug. It has the definition of Penske File from the Urban dictionary. Totally worth the price!

The Urban Dictionary is a unique place to find anecdotal memories on all sorts of stuff. Their ongoing communication once your order is placed is excellent. I have put in a significant number of orders recently, and the communication regarding my order status is excellent. I have had one order misplaced in transit. They have contacted me to say that they will get back to me, but to this point, they have not. So, that's a bit of a caveat in my rating. Overall, I would rate their products and customer service as good. I would not hesitate to deal with them in the future. Fill Your Boots with Whatever You Want to Order. Nice job, "Urban Dictionary."

It is special to have a mug that has to do with my dad who invented a word when we were growing up. He passed away last year. Drinking from this mug is like spending time with him.

This mug gives my life purpose. It's what I've always said. Patience is a virtue and hard work never betrays. Ever since I was born I've been struck with one misfortune after another, but today it all paid off. I got my own mug, and I use it anywhere and whenever I can! Both of my legs are shattered because to my wife threw me in the middle of traffic and my windpipe is messed up due to me screaming all the way from the crash site to the hospital thanks to the unbearable pain I was feeling. Although even with all that's happened this is still the best day of my life. I suppose the only problem I have is that whenever I happen to look at my cup I get a little too happy. That causes problems because my life support can't handle my exhilaration, haha! I'm just kidding; that was just a little lighthearted joke of mine. I actually cannot afford life support because I spent all of my life savings on this fine piece of pottery. Not to worry though! I can get through the pain with my will and drugs - I mean medication. P.S. There are definitely no ghosts in the mugs. Just wanted to point that out in case someone was worried about that.

I bought two mugs as gifts for coworkers and they were very pleased. The print was clear and concise. Hopefully they last a long time.
