I just ordered the 89004 kit which is a header back universal kit for squarebody truck and suv. I’m going to try and adapt it to my manifolds. If that doesn’t work I’ll order headers but would rather stick with manifolds.

Summit sells the Dynomax 89004 kit for $173

Walker / Dynomax makes a manifold kit but it’s more $$$.

You need to supply your own mufflers so I added these stainless 409 magnaflow knockoffs. $44 ea

I’ll add pics once I get it installed in a few weeks.

Here’s my ‘86 k5 305 w stock 4bbl quadrajet, 700R4. Still rocking the stock exhaust which is super thin in spots and the y pipe is beat up by the front driveshaft. Which is why I’m switching to dual exhaust. I’m not expecting a power increase, but would be nice. The catalytic converter was already removed before I purchased, and there are no emissions requirements in my area
