I got the black muffler and the flange is clean and the pipe inside diameter is 19.5mm with no burr or lip inside. It is the shorter body style. There are 12 holes in the inside header tube that are not drilled up into the internal baffles. The holes start at roughly 350+ mm from the flange. So if you cut the stinger pipe off from the inside of the cap it will increase performance on a stock motor. The ID of the outlet tube is only 10mm others ones I have had 12mm outlet. 12mm is better. So cutting the hole outlet pipe out may be in order. A stock motor that runs about 4000 to 4500 rpm should have a header tube length of 400mm to 450mm till it hits some kind of back pressure. The higher your motor max rpm the longer the header tube must be. Thats how a performance pipe works. Second one I bought. The first was the chrome that I painted black anyway.

This does not come with any bolts!! It comes with the exhaust and multiple gaskets. I only needed the gaskets really so it wasn't a big deal but wish it came with bolts. That's why I give it 4 stars.

Easy to install, looks fine. Exactly as described and came with everything listed. Exhaust comes out and muffles the sound better than I expected. Great value for the price.

Does not bother me too much, but it was extremely rusty on the inside of the pipe. Came with bolts and 5 gaskets
