Lightning Headers
OK gentlemen, I am needing some help with exhaust decisions. I am going to be running dual 540 @ 700 HP each. Should I go with the Lightning Headers (http://www.cpperformance.com/product...ng-headers.htm)
or the Dana Marine Flow Torque exhaust systems (http://www.danamarineproducts.com/Pr...TOKEN=92380407) ???
I could use any and all opinions on this decision. Any information would be greatly appreciated!!

I have Lightnings on dads Scarab and they work fine and we have 540's at 730 hp so basicly the same set up. We drain ours after every use so the fact that they are not totally stainless doesn't bother us.

My lightnings work great. Drain aftr every use.
I don't know if I would use them in the salt .
Edit:
Just looked Lightning's site and they now offer a full stainless version. Never mind about the salt.

I have lightning headers on my Dana lake boat and hve installed them on salt water boats also. The powder coated ones are stainless inner pipes and mid steel outers which works great for fresh water. The other way to get them is stainlees inner and outer. The set I put on my boat made alot mre H P I picked up almost 400 rpm and 8 mph on the big end just by changing the exhaust. The guy that owns the company does a great job and I would recomend them.

Put an AUTOMATIC DRAIN on your headers. Just use a fitting at the rear of each each headers water tube, "t" fitting the two lines together then install a thru-hull fitting below the water line. When the boat is trailered or put on a lift the headers automatically drain. This does not cause a water pressure problem either. We have used this method for years on our Lightnings and never had any issues.......
