I think the clearance difference is because I'm using the cast iron water pump. The impeller shaft is shorter. I do agree, stainless pipe would look much better, the issue for me would be, I need to have 3 hose bends to route it the safest way and I'm not sure how it would look. Have you or any one else ever used stainless exhaust tubing, I have a friend at a muffler shop that could bend it for me, and then I may be able to just use 2 rubber bends, ideas?
