Developed in conjunction with the Honda Factory Race Team, this evolutionary new exhaust system combines increased power, light weight, and lower mass to provide an overall benefit to the big Hondas performance.
The pentagonal-shaped muffler features a carbon fiber cone end-cap, 2-staged, stepped baffle and striking looks. The tapered header pipe design progresses in diameter from 1-1/2in. up to 1-7/8in. as it enters the muffler for optimal flow. The RS-4 muffler features a resonator front cap design, that functions as an expansion chamber. The design makes for a quieter muffler with improved mid-to-top-end power. The design is also extremely light but most importantly, the RS-4 design centralizes mass for improved handling.

How an Energy Survey is done.
Heat Loss and heat gain in a building is figured by either manual calculations (manual J) or by using a computer software program. We have done hundreds of these calculations for new building construction. Read on to find out why it is difficult to do one on an existing home or building. It involves finding all the insulation values of the building, measuring the length, width and volume of all rooms, measuring all the windows and glass and recording their composition ( ie: single pane, double pane, low "E" value and other parameters ).
The amount of glass, their orientation, and the number of sky lights will have a big effect, especially on the cooling side of the calculations. Over hangs over windows will also affect this calculation. The tightness of the building construction has to be included as a loose building will allow more out door air to enter the building and let the heated or cooled indoor air escape the same way (called infiltration). There are many other factors involved in doing a COMPLETE Heat Loss Heat Gain calculation, down to and including how many bathroom fans exhaust air from the building. This full calculation is most of the time called an H.V.A.C. Energy Survey. It is very time consuming to do correctly. Beware of a company just measuring the floor space and saying they have done a " Survey ".
A true survey will require help from the building owner to answer questions. For instance, just one example is how do most people who own a home with vaulted ceilings that have been finished with sheet rock actually know what insulation is behind the sheet rock? We know if it were our own home and we hadn't been there when it was built, we would have to " guess ". This makes the survey inaccurate and really not much better than using a general rule of thumb that most contractors use such as 600 square feet per ton of air conditioning or 30 B.T.U.H. per square feet of actual out put capacity for heating.
On existing homes or buildings that already have a heating system, the blower size of the furnace and the ductwork installed in the building will dictate what size system can be installed. It is of little value to do an Energy Evaluation to find that even though a 5 ton air conditioner is needed, the building only has a 3 ton blower in the furnace or the duct work can only handle 3 tons of air conditioning. To put a 5 ton ac in under these circumstances will result in major equipment failures and it still won't cool any better than a 3 ton would have in the first place! The same things happen when we are talking about installing a " bigger " furnace.
If however, you want a true survey and are willing to take the time it requires to find all the answers needed, any GOOD Heating and Cooling Contractor can do a Energy Survey for you at a reasonable cost. This survey should spell out the exact heating and cooling needs of your building based on your requirements for the building. You will sometimes receive a printed report of all aspects of the building. One of these surveys should be done especially on new construction while the building is being built. Some of our local clients ask us to do one to determine if the system in an existing building was ever sized correctly to begin with.

The Dodge Challenger began its quick reign of power in the early 70's and had a four year run and then was put on hold for another four years that was followed up by five more years and then, gone. Until the third generation challenger emerged with full force in 2008. The debut of this long lost beast was Feb. 6, 2008. And yes it does come with a Hemi. Dodge/Chrysler did not hold back when recreating this animal. The first third year generation model was an SRT8 6.1 L Hemi V8 which came in the Hemi orange. The 2010 models will not be available in the Hemi orange but will be introducing the Plum Crazy and the Detonator Yellow. Regardless of what model you choose they all can be pushed to an even higher limit than Chrysler/Dodge had originally planned. One of the most popular upgrades whether you are a car enthusiast or not are Dodge Challenger Performance Exhaust systems.
MBRP exhaust systems have been a leader in the industry for over fifteen years. MBRP has designed an exhaust to system to bring out the full potential of the Dodge Challenger. The MBRP Dodge Challenger line of exhausts covers all of the third generation models. They come ready to push power for both the dual exhaust V8 Challengers and the single exhaust V6 Challengers. The horse power gains that can be expected from the innovation of MBRP are between 20 to 30 extra horses, depending on the engine size. They come with two types of stainless steel, the T-304 and the T-409. Also they will increase torque by about 24 ft/lbs. All of the MBRP Dodge Challenger exhaust system products come with a limited lifetime warranty against defects. And if anyone cares you will be rewarded with conservative driving by increasing the gas mileage by 1-3 miles per gallon.
Next on the list of exhaust products is the line from Magnaflow. Magnaflow has over 25 years of experience in adding a little extra to the exhaust industry. Does anyone remember "Grave Digger"? As a child "Grave Digger" was my favorite monster truck. Magnaflow was affiliated with the driver Dennis Anderson who drove the infamous monster truck. Where performance mattered most, for life and a career, Magnaflow has and will continue to be put to the test. They have since moved on to a much bigger world trying to take on most car and truck models. These systems will give a Dodge Challenger a more agressive sound that we all love. They will also improve gas mileage, horsepower and torque. A price cannot be put on the beauty that this system will bring to the already beautiful Dodge Challenger.
The third and final line of exhausts that we will touch on is the Corsa Exhaust systems. Corsa started with the rival Corvette in 1998, and ventured off to create what is now another one of the leaders in the Performance Exhaust realm. Corsa has one of the most advanced exhaust systems in the world. They are tailored to deliver exactly what the Dodge Challenger needs to outperform the competition. They were designed to maximize horsepower, eliminate drone while cruising and the sound that it will create will be the voice to fit the personality of the Dodge Challenger.
There are many other exhaust systems available on the market but for time we could only touch on a couple. They were not put in any specific order and they will all increase the performance of any Dodge Challenger. Drive hard and have fun doing it!
