Yep those things have to built piece by piece. From what I've learned so far the kit alone by kit I mean, different length pipes straight 45 degree 90 degree etc, is about 400 alone. Then you have the fabrication time which in pretty sure is almost as much if not more. Oh I forgot the kit only comes in raw material so there's another 300 for ceramic coating them not to mention the flanges to bolt them up too your heads oh and did I mention the couple if weeks without your boat cause every time a pipe gets added it needs to be test fitted. Worst case 2000 best case 1500...am I wrong here.
