Replace the hard lines coming from the prop valve (the ones with the coils) with stainless flex line, and use AN to hardline adapters to tie back into the steel lines?

I think it would give a cleaner look, make more room for exhaust, and still retain the flexibility that the coils were intended for.

 

never seen it on a 3rd gen, but they came that way from the factory on my 04 silverado

im sure finding all the fittings to adapt to the flex lines would be tricky though.

 

Wouldn't happen to have a pic of that would you?
