Doesn't fit FMF MegaBomb

Has required adding spacers and getting longer bolts to fit without touching the FMF MegaBomb header. 2008 Honda CRF450R Nice to have a solid guard to protect the header pipe, but wish they would do a better job sizing the protector (diameter is too small), and the standoffs (too short) so it would fit without touching.

The muffler install was very easy. Very good product and it change the sound compare to the stock exhaust. The exhaust is really loud I highly suggest to people who run a one cylinder bike to buy the p1x if you love your neighbor.

Sound great looks great. Way loud, it's louder than my Harley. It actually hurts my ears. I got the 1.25" quiet core and it doesn't sound as good with it in but it makes the volume manageable.

Heavy duty.

The metal is nice and thick which also makes it difficult to bend around the pipe. Bend it to fit the pipe lengthwise first and then concentrate on bending the tabs around the pipe. Like the posts say - use a hose clamp to bend the tabs around the pipe. This worked very well. I added a couple of extra hose clamps from the local hardware store to further secure the guard. I heard it can rattle and I just wanted some extra protection. It will take a while to bend the guard so that it fits well -- longer than I thought. I like the guard, but next time I will buy the carbon one due to the install time.

Shipping and service is always excellent with mcss, the product itself is what i expected, looks amazing, sounds amazing, gives me a little more power, or at least feels like its snappier. Airbox gutted, jd jet kit, etc.. I run in Supermoto trim, and im a little worried about getting grief from the police in the small town i live in, because of the sound of the exhaust. Its pretty loud, i love it, but its pretty loud.
