I got my EPCO's for around $400'ish. I asked for the the pipes to be the same length of the stocks. When I got them, they were a little bit longer than that, about an extra 3-4 inches. I think I paid like a $40 or $50 up charge for the custome length. Awesome pipes. Love the way they look and their sound is even better. I noticed a performance gain. Wouldn't call it significant but definitely noticeable. Took me a while to minimize the popping on decel. Great folks to deal with.
