Just got back from the exhaust shop. :D
2.5" pipes and 40 series Delta flow Flowmasters.
What a freakin differance from the rams horns and 1 3/4 pipes.
Took off like I normaly do and it broke the tires loose and went sideways.
Pretty cool except I was not even expecting it. And that is with 33's and 3.08's.
I expected to gain a little power but was not expecting that.
The neighbors are unhappy with me now, wait till they get a load of this HA.
:D
Damn that rig sounds cool.
 
Good deal :D . I love the sound of dual Flowmasters!



I have noticed a direct relationship between my MPG's and exhaust sound

Stock exhaust = good gas milage

Cool sounding dual exhaust = horrible gas milage



Must be how my driving habits change? I tend to run the snot out of it when it sounds cool. :D
 
I know what you mean. I just got my '86 done. Newer 350 with a Th350 and dual 2 1/2" exhaust with dual flowmaster 40s. It is really loud. I have not kicked the 4 barrel in yet becuase I need to do some work on my linkage. But the truck sounds cool. I love passing hot rods and being the best sounding truck. I am running headers and a H pipe.
 
I origrinally installed a 3 inch 40, but it was too damn loud. I changed to a 70.
It still sounds nice, without damaging my hearing anymore than it already is.
 
oh man, i dont think it could ever be too loud. i love the sound of just headers. :cool: a buddy of mine is currently runnin jus headers cuz the old stuff jus fell off on the trail, and hes too lazy to put it back on. sounds like a dragster. fortunately the bears havent pulled him over yet.

congrats on the new pipes. if you regear, you might not be able to keep tread on ur tires very long.hehe
 
Too true!

But when I tow my camp trailer through the mountains it was ear shattering a little too long.

My dad has really bad hearing and it bothered him too.
 
I ran the Holley Flow techs, Only snag was with the clutch Z-bar.
Had to cut the arm off and move it outboard a few inches to clear the rear primary tube. Good thing I decided to let the exhaust shop remove the old stuff and put everything back on or I would have had to drive it there with
no clutch, not a big deal but in traffic it can be a real PITA.

I have never ran Flowmasters but these Delta Flow's sound nice taking off and mellow out pretty good when cruising. With the top off and no floor mats or carpet it isn't bad at all, it's a hell of alot quiter than my old K5 with the back of the mufflers blown out.
 
I love mine...73 K20 with 450 HP 383 with cam and gear drive and dual 40 series Flows. In my 'hood theres quite a few newer Tahoes, Silveradoes, etc. that they slap on a cat back kit, lift it to fit pertty, shiny wheels and mudders that will never see a dirt road. And I have 30 year old paint, rust, dents, all that good stuff. The look on their face at a stoplight when they realize all the noise is coming from me is priceless. :eek1: Light goes green and I mash stupid pedal. Its great!! :haha: :haha: :haha:
