LS exhaust (ing)

[donandal]

I've spent the last week reading up on exhaust systems.

I need to build one for my 53 AD with a GM 5.3 connect
and cruise E Rod setup.

My setup included GM manifolds and CAT converters, so
I need to build the rest to the back. it's 2 1/2" leaving
the converters.

Lots of google time, but it is exhausting trying to find definitive
info about dual vs single systems.
I'm only going to build it once (stainless mandrel bend custom).

I want a nice quiet factory sounding setup.
Too old, don't need the noise.

on the other hand, I don't want to just throw away performance.


Ideas?
