4-2-1 Headers

Postby mlopez [OP] » Aug 01 2020, 3:59am

I was looking for headers for my 2016 Silverado 1500 5.3L, and most that I found were long tube 4-1 headers, or shorties. I only found one that was 4-2-1. Does any one have info or links to more long tube headers that are 4-2-1 or tri y?
Thanks!!

I am guessing these are the only Tri y headers you found? That is one thing I hate about the internet. you search for one what should be simple to find item but because of paid placement contaminating the search results you have a hard time finding what your looking for, to make it worse they will even include pictures and wording on their links tricking you to click on their site to only find out the item you clicked on is for another vehicle entirely and now that you clicked on it that damn ad shows up on every damn web page you visit.
In Short I only found one Tri Y header yet I cannot even be sure they would work without bashing them into place.

They are nice looking headers one the reviews I saw they guy hated them since the coating peeled off and they rusted pretty bad.
Bit pricey for that kind of issue.
