hey ive seen and heard alot of older muscle cars, and ive always loved how they have a kinda hollow idle.

i wanted to know if someone could post what kind of mufflers they are or waht i cna do to make it sound like that. im taking auto shop, so cost aint a problem, i get school discount,

and ground clearance wont matter, this is on my 78 truck, so i also dont need emissions.

right now i do have LT headers, and 2.5inch duals that exit after the rear tires, but the exhaust is too quiet.

also in a few months i will have like a 300 or more hp 327 in it, so i want it to sound sweet when im running her up to 6500.

thanks

 

no one knows?

 

for starters, most hotrods don't have cats. that might be a good place to start. most of them are probably true duals as well.

 

Carb + CAM...

More air movement makes more sounds, so i'ts hard to make a mouse sound exactly like a Rat, but still mouse does sound good to me...

When you see a Old MuscleCar , if you can, ask the owner what are is mufflers... my friend has ThurshTurbo on is 73Nova, sound nice but not badass, he has a 307 with unknown cam.

I do like my Spintech alot, great idle too, when cold it sound like i have an high lift cam (i have carb issues and it idle at 500 rpm cold)

 

Yea, most hotrods have wicked cams :-)

 

like i states in my first poist, this is on my 78 chevy truck, has duals, 2.5inch.

ya i hope to have a insane cam in my 327 im building soon, im hoping to get like 380hp out of it. and i want it to scare little kids and old people, along with **** off soccer mom's in their SUV's on their cell phones. :lala:

 

With your setup with no cats(if you have them) and good mufflers should sound very nice. Engine has alot to do with sound though. A killer high compression big race engine will sound much louder than a streetable 327 with the same exhaust.

 

yes i know that about the motor size, i was just wondering about what brand/model mufflers, i know about the motor and crap, i know my engine will be breathin enough to make it like that.

and my compression is going to be about 9.9:1 or so. dunno know yet.

its stock pistons with 58cc chamber heads in a 327.
