This is a FMF 4.1 with the old style Powercore 4 can for an Extreme pitbike.
I bought this for $200 plus shipping last year and never used it.
The can has some scratches and a small ding from mounting.
The main pipe is 1 5/8 inches OD. The end pipe is huge.
It includes all the hardware, instructions and stickers.
Price dropped $150 shipped.
