Just an FYI---My Stellings "Green" full length tubular headers are almost 15 years old and have over 400 hours on them---all fresh water. I have even slightly overheated them once years ago---no cracks, leaks or problems to date. (565cid N/A 600+hp)

smitty i have same headers the risers are small alum. do your pipes go out of the boat , i don t no if i should buy the dry or the next set down ???

For what its worth I thought I could add my 2 cents.... I have used both wet and dry Lightning systems and have been very pleased them. I used the standard (wet) system on a stock internals 454 mag for more than 600hrs with no issues of corrosion or faulty craftsmanship. I boat in freshwater only and drain them after each use. Currently, due to cam profiles and HP numbers as CP Performance mentioned I am using Lightnings (dry) system. Although I have not used headers by another manufacturer, I would highly recommend Lightnings based on my experience with them.

that fine if you don t have any , but i had ss header for 15 years now .i put 540dart with 600 ponys all i need is longer risers . my? is how long can i go i like to keep my tail pipes
