Best music I've ever heard on a marine exhaust video!

Can I suggest two things..1 use a larger cup, 2 learn to use your left hand...of and the music..no buenno.

No shots of the system installed? How do we KNOW if all that work actually fit? No smiling customer?

I wanted to watch your video, but after 30 seconds I was thinking about blowing my brains out due to the horrible music

where is that quality? without purge gas

[@SPEEDBOATMANIAC410]

** Its a shame after 100- 200 hours the tig welds will rot out from salt water ?! GOD Bless

If you can afford a boat that needs exhausts of that size, you're either making money with the boat, or....you can afford the upkeep...in other words, "if you have to ask, you can't afford it."

This because the welds were not back purged with inert gas? I came to this video looking for how I can properly make headers for my 6.2 and want stainless exhaust DIY
