Awesome Performance

I wasn't sure with M4 as they are not as mainstream as the major players, but their quality is equal to anything else out there. They also produce a supper deep sound and improved mid range performance. Very happy and impressed.

Amazing pipe

This pipe is much better then the stock pipe on my 2005 honda cbr1000rr. It's loud but not to loud I could easily do a multiple hour ride with this pipe without getting a headache. It has a nice deep tone all the time.

M4 exhaust

Great look for my yellow and black R1. The sound and power difference is very noticeable.

I recommend them for anyone

This is a great pipe, sound, and looks. For the price it can't be beat. Gets rid of that nasty little heater next to your leg as well, and lets your bike breath. Remeber, a motor is just an air pump, the faster you move air through it, the faster you go, and these things really open it up.Very easy to install as well, which is a real plus since so little is on the 08 R1's.
If your looking for a pipe, get this one, you will love it.

Is it louder than the Leo Vince?

A: No modification would be required. You would simply remove your stock Mufflers and install the M4 mufflers in their place. Unfortunately, M4 does not provide DB levels for each of their exhaust systems but do say the M4 slip on will increase the performance and the sound of the bike.
Q: Is this exhaust a dual outlet for the 04 honda cbr600rr?

A: This M4 exhaust for your 2004 Honda CBR600RR would still be one single undertail muffler.
Q: Do i have to cut my stock EXHAUST PIPE to put on the slip-on.?
Over 7 years ago
From what i see the '05 CBR600RR pipe is a straight pipe to the header, does this mean i have to cut the pipe off and put the performance exhaust slip-on onto it. or is there a stock cut on thepipe somewhere closer to the header that i dont see. Also how long is the slip-on pipe for the Jardine RT-1 dual exhaust and the Yoshinura slip-on. thanks
