2021-2023 Yamaha YZF-R7 stainless steel full system with carbon fiber canister, manufactured by M4 Performance Exhaust Systems.

* Stage 1 "Q8" Quiet Insert is included with your purchase, a $43.00+ value *

The system is practically brand new. It was installed on my bike for only 1 track day (~50 miles).

As you can see from the pictures, besides the pipes being blued, it looks like it just came out of the box.

The install on this system is very easy (3-pieces really helps). It sounds fantastic! It's got a really nice deep twin thump to it.

I'm selling it because I purchased two different full systems due to a back order at the time, and now I only need one of them.
