Header Collector Ball Flange Kits:
The Flowmaster Ball Flange Kit
takes the place of messy three bolt flange type connections and allows for a leak free and gasket free ball flange type connection. All kits are 16ga aluminized tubing and are sold in pairs.
The size of tubing
used in an exhaust system is as important as selecting the right muffler. Your tubing
diameter choice will affect the sound level and performance characteristics of the muffler, but keep in mind that bigger is not always better. Using tubing
that is too large can actually hinder exhaust scavenging by slowing the velocity of exhaust pulses in the tubing. As a rule, most stock street applications running dual exhaust use 2.00” through 2.25” tubing, and modified street applications (dual exhaust) will generally use 2.25” or 2.50” tubing. Very rarely will 3.00” tubing be used in dual exhaust street applications.
In general, the following guidelines should be applied for street applications:
Single Pipe Diameter
2.50" / 150-200
3.00" / 200-250
3.50" / 250-350
4.00" / 350-425
4.50" / 425-500
5.00" / 500 and up
Dual Pipe Diameter
2.50" / up to 400
3.00" / up to 500
3.50" / up to 700
4.00" / up to 850
4.50" / up to 1,000
Balance Pipe(H-pipes and X-pipes):
strongly recommends using a crossover tube, otherwise known as an “H” pipe or balance pipe on all true dual exhaust systems. The crossover pipe equalizes the exhaust pulses and allows the sounds waves to communicate between both banks of the engine. Not only does this usually improve torque in the low to mid rpm range, it also creates a deeper mellower tone both inside and outside of the vehicle and helps eliminate “back-rap” on deceleration.
has performed extensive testing and determined that the “H” and “X” pipes deliver no significant difference in performance, but do affect tone, the “X” pipe giving off a higher pitched tone. Flowmaster Scavenger “X” pipes
however, do increase torque through use of their patented D-Port technology and retain the deep Flowmaster
muffler tone desired by most performance enthusiasts.
The sound of your exhaust is much like music; we all have different preferences so it’s important that the system be “tuned” to what you like. With the Flowmaster
family of products we can help accomplish this by answering the questions below. This approach will allow you to choose the best product to suit your needs and expectations.
1. What is the vehicle year, make, and model?
2. Which engine do you have or how much horsepower does it produce?
3. What is the vehicle used for? (i.e.: daily driver, race, towing etc.)
4. Preferred sound levels (interior and exterior?)
5. How are the space requirements?
6. Would you like a complete exhaust system or universal pipe kit if available? Single or dual outlet?
Adequate hangers should be used to properly support the system. Flowmaster uses OE style hangers in all systems.
are designed to be used in conjunction with your mufflers for improved sound reduction. Resonators will help to eliminate interior resonance.
Stainless Tips/ Exit Location:
highly recommends running a minimum of 12” tailpipe after the muffler. This will not only greatly help in sound control, it will also provide an increase in exhaust efficiency (more power). Running tailpipes out from under the car in street applications will also direct the potentially harmful exhaust fumes away from the vehicle, as well as minimize the sound transmitted into the cab area of the vehicle.
