Exhaust 305 v6
Hi everyone,
I’m new to this forum but I have a ‘68 GMC C25 with an original 305 v6. It sat for many years and I need to replace some of the worn out/rusty parts. It runs and exhaust isn’t rotted out yet but what is everyone using for an economical exhaust setup from the motor back?

I have a 68 K2500 and run 2 1/2 inch dual exhaust with 50 series Flowmaster mufflers.

Re: Exhaust 305 v6
Went with 2.25 dual exhaust on my 305 with flowmaster 40's.
Here's an old video. Skip to 1:05 to hear the exhaust. https://www.youtube.com/watch?v=RCfanx30JO8

Re: Exhaust 305 v6
Has one heck of a nice idle sound. We came through Cave Junc. earlier this year. Really nice area.
