The Stovebolt Site Forums The Shop Area General Truck Talk What Mufflers on Dual Exhaust 235?

I installed a set of Fenton headers with 2" dual exhaust and glass packs on my 57 last fall. While I do like the rumble at low rpm, I don't like the noise at the higher end. What are you guys/gals using that gives you that nice rumble but yet you can get out of the neighborhood without waking the dead?

Wake them up. If I can't sleep neither can they.I have my two smitty glass paks still in the box. Run straight pipes and save the $$. If you run the pipes striaght out the back and you won't hear them as bad inside the cab. SO my vote is STRAIGHT. (or use Smitty's)

What size glasspacks are you running???

Jerry, I run 30 inch glass packs on my 46, and it doesn't seem that loud at all. I can still carry on a comfortable conversation inside, and it just cackles slightly out back. On my 52, I've got performance mufflers, and they have a lower more mellow, V-8 sound.

I believe mine are 20".

It does seem to make a difference as to how you "exit" or terminate the exhaust. I have tried it several ways and even with steel packs like I run, which are l-o-u-d, straight out the back is not that loud. If you run them out the side or terminate them anywhere under the body or bed or in the back of the rear fender of the truck, they are louder than if you terminate beyond the furthest most rear point of the truck.

Alvin - are you really running straights? I've thought of running straights but I haven't had the guts to do it! That is really the 50's sound!!!!

Run some 27" 0r 30"'s,my dad runs them(27") on his 50.He does not like it so loud now that he is older.As for me,I run 1 1/2 straight pipe to get the most awesome rapp that you will ever here!

i am using some cheap mufflers that they put on with the duals pipes. sounds like quiet flowmasters. will put on flowmaster 40's later. RON

Jerry,I am running Flowmasters,but mine is a V/8.If I really get on it they are loud,but if I drive normal they just have a low rumble.

Mine run out the back. The pipes are 2" (outside diameter). So that's probably 1 7/8" inside??? At high rpm she sounds like one of those Honda's the kids are driving. It sounds more like a high pitch vibration than anything.

how about Supertraps.there tuneable.I run 3 1/2 " outlet on a 350

I'm running Smithy's sraight out the back on a 350. They are very mellow in the cab. My neighbors are glad I got them, before it was open headers. Smithy's are cheap too, $25 each...

Joe, I truly am running straight pipes on my beefed up 350. Man does it count them off. I can go to a show or cruise and everyone loves it. A couple guys in the club have actually CUT OFF THEIR MUFFLERS saying they love the way it sounds. I also truly have a set of Smitty's that I ordered from Custom Supply out of Florida. I just can't bring myself to put them on. You were right to about how you exit the pipes. I had a set on a 78 once that turned out behind tires like original and I couldn't stay in the truck with glasspaks. Ran them Straight out the back and it wasn't so bad. I may never put mufflers on my 37

Try using some glaspacks that are straight through,and just slide 'em way down the exhaust pipes until the pipes come through the other end,then clamp 'em;add your tailpipes and hangers. VOILA! Straight pipes sound-but it has mufflers! From experience...

A fifties trick I have heard of is this. With a six with a split manifold keep the stock muffler on one pipe and a glasspack on the other. Or a glasspack and straight pipe. 3 cylinders sound off while the other 3 are sudued. blo blo BLAH BLAH BLAH blo BLAH sound.
