Why did i do that?
Truck had some mufflers from the 70's and a 327. Well 327's are crackly with headers and long story short i grenaded a rusty old muffler but before that the truck sounded bad to the bone! Very open flowing it was kinda too loud but sounded great. I have a 350 with a 268h in it now and with the old mufflers (tuning out the blown one lol) you could hear the cam really good it sounded like a race car! Choppy at idle and roared up till about 4K then it was raspy and sounded awesome at anything past that. Well I just put super 40's on it and I hate it. It sounds like a newer car just s quite constant hum. It never gets raspy or a little crackly. so now I don't know what to do.. I miss the old sound but no idea what kind of mufflers they where.. It doesn't ever like hit that point of when it really seems to open up..

Re: Why did i do that?
we used to take a long chisel and knock the baffels out of mufflers for a better ( louder ) sound .

Re: Why did i do that?
Sounds like you may have had glass-packs. They get real loud in the upper RPM range.

Re: Why did i do that?
You can get a short turbo muffler from thrush or cherry bomb that would probably be what you're looking for. And yes they do look like a "regular" muffler. I'd
go with glass packs though to get the sound you're describing.

Re: Why did i do that?
It's never been so hard to describe a sound...

Re: Why did i do that?
Maybe check with neighbors for second opinions?
Or with the war department: "I heard ya comin Leonard; ping, ping, ping all the way down the street.. if you think, that for one minute, etc."" |

Re: Why did i do that?
Get a set of headphones and watch some YouTube videos searching "small block Chevy turbo muffler" or whatever. It helped me a lot when deciding what to with the Silverado I had.

Re: Why did i do that?
I just did the same thing, ran new exhaust and replaced my Turbo muffler with a Magna flow, I'm going to get an H pipe and see what that does before messing with the muffler again.
