Yes, they are baffles and have received a Utility Patent from the United States Patent Office for an exhaust baffle, patent # 6,848,252.
We do not recommend running without a baffle due to the large loss in both torque and the midrange power band where most folks do 98% of their riding.
Yes, however we have not found any noticeable loss or gain using torque cones.
I have read on the internet that people love the sound of your Thunder Monster Baffles. I have read that some definitely noticed an increase in power while others say the power seemed to remain about the same. Why is that?
Actually they should all experience an increase in performance with each installation. The issue is some folks do not install the Thunder Monster baffles in the proper location as explained in their directions. Another important point is, some folks are not willing to rejet or remap their bikes when a fine tuning step would provide excellent results. In a properly tuned and equipped motorcycle our products are a bolt in application, however as with any performance product if a fine tuning step is required it is absolutely necessary for that step to be taken. Anything less will always produce inferior results.
As a footnote: It would not be reasonable to expect our product to overcome a poor combination of equipment, ie cam selection, head work, improper jetting/mapping, etc.
Yes, you can order single baffles by phone.
Our standard shipping is UPS Ground, and will ship from Charlotte , NC . Products generally ship the day you order provide you order before 3:45 pm Eastern Time. There is a map with time in transit estimates available on our web site. If you are in Alaska ,Hawaii , or an international destination we will ship by arrangement.
If you have an existing hole in your pipe for a baffle and it is in the proper location it will take approximately 5 – 10 minutes. If you do not have an existing hole or it is not in the proper location, allow for the time it would require to drill a ¼” hole in each pipe.
Measure the inside and outside diameter of your pipes at the exit end and also the outside diameter of your baffle at its end. DO NOT MEASURE YOUR HEAT SHIELDS. If you have gutted your mufflers or removed your stock baffles call and ask for a tech person. (Diameter: The distance across a circle.)
Yes, out products produce a deep,clear, throaty, hot rod/hot bike sound and will outperform a cut down baffle. Cutting a baffle is diminishing the performance of its intended design. Normally cutting a baffle decreases the performance and while it will make a louder sound, it will not produce the “quality” sound you were expecting.
Provided your bike is properly jetted or mapped at the time of installation for a free flowing exhaust, our products should be a bolt in application, however due to the variables in carbs, injection, cams, set ups, tuning, etc. No performance product is an absolute bolt in 100% of the time.
Will your products improve the performance of my straight/open or unbaffled pipes and specifically help eliminate the “flat spot: or hesitation without losing a good sound?
Yes, our products will improve the overall performance of your unbaffled straight pipes and still maintain an outstanding quality sound. Any responsible tuner should inform you that it is literally impossible to tune a bike with straight unbaffled pipes for the various rpm ranges we encounter during normal riding. It is an absolute engineering fact that straight unbaffled pipes cannot bring out all the potential performance from your engine in the various rpm ranges we encounter during normal riding. Under wide open throttle unbaffled pipes, or pipes without tuning devices are acceptable and can be tuned for that one specific rpm, that’s why they are called drag pipes. Actually, open pipes can have a negative long tem effect on an engine that is primarily used for street riding.
In a properly jetted/mapped bike our line of products are designed to provide you with the proper amount of back pressure, enhance flow dynamics and help deal with reversion waves during cam overlap for overall improved performance. They additionally deliver a deep, throaty, crisp, hot rod/hot bike sound.
Yes, in some applications. If you have a stock exhaust system and have gutted your muffler or have a removable baffle please call and ask for our tech people. They will explain a possible alternative solution.
No, unfortunately we do not offer custom made baffles.
