'84 K5 Build (Midlife Crisis)

My 66 C20 has the trailing arm with coils for rear suspension; I should have taken pictures of all the twists and turns in that exhaust to get it up and over the axle and out the sides behind the tires. I cut it off and goes out the sides in front of the rear tires. I thought it might be louder, but I don't feel it is. I did go from glass packs to Flowmaster 50 series delta flow mufflers.
 
Let me know if it's any quieter driving around with it like that. I'm debating doing that with mine because dumped is just to much.
DON’T DO IT!!!
Holy sheeze balls, I should have left it the way it was haha. I MISTAKENLY thought adding three 90’s and a 45 and discharging out the side would be quieter than just a dump onto the ground. My left ear still hurts from the test drive. Window up doesn’t help much either. :dunno:

I thought about mentioning Wade's Jimmy was still pretty loud with the side exit. I think he was running Super 40's. You probably need to try a different muffler.

Agree, but unfortunately the round bullet type is the only one that will fit in either location. I just ordered some Patriot inserts. See if that tones it down.
 
What's a patriot insert?

Yep, you need a real muffler for that. Even my huge magnaflow side exit can get kinda loud sometimes.
 
I'm very interested to see what those auger inserts do for your sound. I'm running dual 3" exhaust on mine with 4 perforated packed mufflers - 2 ovals right by past the doubler, then an offset up with 2 of those Kooks bullet perforated packed mufflers as it crosses over the rear axle then a slight kick down to exit straight out the rear. I used to love the sound of the oval packed mufflers which I know are getting burned out as they always do. I recently added the 2nd set of Kooks hoping to cancel out the obnoxious drone I have at about 1200 rpm. My rig is just a trail truck and its really annoying when crawling around (maybe I'm just getting old?) Mine sounds really good under full throttle and load, its not even that loud but the low frequency drone off idle is terrible. Those auger inserts or there are even mufflers made with those really quiet down diesel trucks and take the drone out I've read, I don't know how they work on a gas motor?
