If you do not have a downpipe it would be highly recommended to keep your egt's down and would have the largest performance gains. If you are looking for a mid-pipe you can have someone fab one with mandrel bends fairly reasonably or you can go to any exhaust shop and have them fab one with crush bends if you size the pipe 1/2" to compensate the crush bends and get the same if not higher performance then the 3" mandrel bent pipe for a fraction of the price. It all depends on your budget. I would guess for the crush bends you would pay somewhere between $100-$200 and for the custom mandrel bends pipe $400-500 plus materials which you can get from Wolf Aircraft for around $100. Wolf Aircraft also does black label products and if your nice to them may already have the pipe in there cnc mandral pipe bender.
