My dad had a tricked out 98 GMC 454 dually with mufflers I loved the sound of. He said they reminded him of a corvette.....anyone have any clue which one it was? anyone have suggestions? I want a deep roar that screams power.......

 

go to the manufacturer's websites, like flowmaster, magnaflow and others. They have sound clips.

Try flowmaster 40's. That's what I got. If you click the link down in my sig there's a sound clip of it. It's on stock exhaust to so You can imagine if it had a performance cat, headers, bigger pipes etc...

If that's not loud enough for you try flowmaster 10s. If that's still not enough just dump the exhaust after the cat.

 

Some old Thrush juice cans! God I used to love those!

 

Don't forget coffee cans

 

Magnaflows have a better, cleaner, more sporty rumble.

Flowmaster is loud and raw, like trucks are suppose to be.

I have a Magnaflow and love it, but Flowmasters are awesome too.

 

I just checked Flowmaster and the 50 & 70 series are made for big blocks. I remember the 70 being a very typical application. I don't think it would be appropriate on our trucks, but there is a good chance that is what was on the 454.

 

I'm thinking of waiting untill I have the money for the whole nine yards (headers,cat, and mufflers); My plan is to get the tubular headers that join to one pipe, get a 3.5" cat, and splitting to two 2.5" pipe out the back. This way I can use just two o2 sensors and keep my ecm..... Should this work? Also, do you get more rumble from two mufflers or just one?

 

Im also thinking of exhaust cutouts (just in case I want to be highly annoying).....
