84 K10 full exhaust replacement

[K10noob182]

Hi everyone, I recently bought an 84 K10, SM265 Manual transmission 4 of the floor, it is all stock except for the 350 crate motor in it. Stock 84 oem exhaust manifold going into a poorly-contructed Frankenstein exhaust that must go.

Goal: Torque off the bottom to mid-range. Mellow "turbo muffler" dual exhaust out the back. (I'm 55 years old)

It's not the kind of truck I would be revving to the moon and grabbing the next gear.

PLEASE give me your opinions on the best set up? Cost isn't a huge concern if the value is there. I don't care much how it looks under the hood, but I don't like chrome. (just my preference)


My original plan:
1. Summit Ceramic Coated Headers for 4WD Chevy/GMC K-Series Trucks Part Number SUM-G9109 that were recommended by Summit support.
2. Two Summit Turbo 2.5 Inch Mufflers SUM-641125-XL
3. Exhaust shop would do an X pipe running dual exhaust out the back all 2.5 inch.

The headers didn't even come close to fitting. It hit the motor mount on the driver's side AND the frame at the same time. I had an experienced squarebody mechanic verify this.

I'm really enjoying learning the truck, had a K5 in the 90s, but I'm pretty frustrated. Burnt both forearms on the exhaust. Wife thinks I'm nuts.

Thanks for reading.

Installing a New Exhaust System Including Headers

I am installing a new dual exhaust system on my stock '77 K10 to replace the swiss cheese straight pipe. I am also installing long tube headers. I have the passenger side header bolted in and the collector flange is touching the driveshaft. Any tips on bending it to clear? I am reluctant to heat...

I used Hooker manifolds and stock dual exhaust, with the Turbo mufflers that aren’t aggressive.

You are nuts... just like the rest of us. Curious to see what you wind up going with. Pics when done please. Always been a big fan of headers but those Hookers are just sexy!
