Q: Why should I purchase an M4 exhaust system?
A:
The simplest way to gain performance is with an aftermarket exhaust.
At M4 we take the time to make sure the performance gains you get are the best possible. We won't feed you unrealistic or impossible numbers. You will get a real performance exhaust system, with horsepower and torque increases all thru the RPM range.
Q: Do I need to re-jet or re-map?
A:
It is not absolutely necessary to re-jet or re-map after installing a new M4 system. Your bike will run fine if you don't. In most cases, however, the ride and performance will be enhanced with optimal jetting and mapping.
Q: What does a M4 exhaust sound like?
A:
Well to be honest, most aftermarket systems sound pretty much the same. Some have a deep sound and some, after a few miles, have a raspy sound.
We feel our systems have a deep, mellow sound. Most systems are around 92 to 98db's.
If you run your rpm up to the rev limiter the db's may go as high as 100 to 102db's.
Q: Are M4 systems street legal?
A:
No, there are no aftermarket exhaust systems that are street legal in the U.S. market. M4 systems are designed for closed course racing.
