Can't remember how long exactly it took but it was a long while before I got them. Had to send them back cause fitment was messed up which took another two months or so. Everyone raves about him because he is a good guy and stands by his word and his products. Something I didn't keep in mind when I ordered mine is that these are quality custom made exhaust that are made and not an off the shelf from any vender. So at times it was a bit frustrating for me when it was taking long or not fitting right. Worth the wait in the end I think so, S*** still puts a big smile on my face everytime I start the machine.
Hell, I had more trouble getting my old Termis to fit. When Mark was finished with mine, they fit perfectly. The custom tips he made for me stacked with only a 1/4 inch of gap and sit within 1 inch of the back wheel. How he made them fit as well as he did without my bike is beyond me.
Here nor there, though. Waiting for or fight fitment issues is frustrating, no matter what part it is.
