Frankly, I just can't understand how anyone anywhere anytime can justify making a mess like that.
Yeah, I'm well aware bought headers often have fit issues.
I've been building cars for over 5 decades, and I've never let a car leave with even dimpled primaries.
And I'll fix interference issues for free if the client can't afford it, because I'll never be associated with mangled hacking messes.
But, you know, that's just me. And I'm so very very glad I'm wired like that.
Rant over.
EDIT: Probably the same guy, after "learning to weld and doing it right".
