6 cyl. Exhaust Setups - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Just was wondering what exhaust setups you guys had on your 6 cyl. trucks.
Vids would be sweet

70 shorty · 07-01-2009, 12:08 PM

I have a header going into duals that exit in front of the rear tires. I can't tell you manufacturers, my uncle built the truck before I got it. The mufflers I think are just turbo mufflers. It is loud, especially going down the highway.

bttt..

Elephanthead · 07-01-2009, 02:27 PM

I have a rusty pipe that comes off the manifold, that bolts to a rusty muffler, that bolts to another pipe that points out the back. There are also a couple of rusty hangers keeping the whole setup from falling onto the ground or shaking loose.

My set up exactly except right after the rusty muffler it rusted off

Shyguy · 10-20-2009, 07:35 PM

I guess the rusty exhaust must be popular because mine is just like the guys with the rusty exhaust.

One difference is mine has metal coat hangers to support the system.

I used my '67 swb stepper with a '96bed with the rusty exhaust today quite a bit to carry supplies for the fence I am building.

Since I am going for a stock look on my truck when I restore it, it will have the single exhaust similar to the orginal and an original style bed.

PanelDeland · 10-20-2009, 07:53 PM

I also have the rusty exhaust option.If I had more fun tickets I would run a set of headers and duals with pipes all the way out the back.Probably one of these header sets.

I do have a 4 bbl mani fold for the 250 in mine but 390 carbs are a bit hard to come by and require more fun tickets.

**slomotion** · 10-20-2009, 10:09 PM

Here's a pic of the set up on my 292. It's a set of Langdon cast iron headers from Stovebolt. (re PanelDelands link) They both dump out pretty close to each other and have 2" primary pipes. The cast iron also tends to keep the under hood noise and heat down. I didn't want to go all the way across the truck for duals, and didn't have many options for two mufflers, so I found a new (Mieneke) muffler that had a three inch inlet, and two 2" outlets. I don't know what this muffler was designed for, but I could see through it both ways, so I put it on backwards. I can't prove it, but I'm thinking I didn't hurt the flow much because of the flow-through design, and the 3" outlet. I put a smooth 45 deg down-turn on it just behind the cab and it has a nice subtle sound going down the road.

**Boog** · 10-20-2009, 10:38 PM

That's a good looking 6 there slomo.

silverstreak · 10-20-2009, 11:11 PM

This is in my 63 Belair, but the same can be used in a truck.

Langdons cast iron headers (ceramic coated)
Offenhauser 3 1 bbl intake
3 Weber Outlaw 2 barrel carbs
1 7/8 homemade exhaust
Dual Smithy's glasspack mufflers

I'm still in the process of finish welding the pipes and fabricating the carb linkage. I'll fab some tailpipes at a later date. The X frame is tricky to run duals on one side.

'72customdeluxe · 10-20-2009, 11:20 PM

I would either make one soundraspy and old school or go with longtubes into 2.25" dual exhaust, to an x-pipe and then some straight through mufflers. My preference for those being Dynomax Bullets and Ultraflos depending on how loud you want it. This would be an attempt at recreating the sweet exotic BMW inline six sound. You'd probably have to bump compression and rpm way up to accomplish this though.

culp7 · 10-21-2009, 04:21 PM

Smitty's or Cherry Bombs?

Tx Firefighter · 10-21-2009, 06:42 PM

Smithys stay quiet for the long haul. Cherry Bombs get progressively louder as they age. I've run Smithys for 25 thousand miles and they stayed real quiet. Can't say the same for Cherry Bombs.

Choose what sound level you'd like.

samwise68 · 10-21-2009, 08:53 PM

I'm really considering Porter Mufflers for my next build, either that or making my own steel packs somehow.

Check out Porter Mufflers - their sound clips are on V8's, but, they're a traditionally made muffler, and I like the sound personally.

I want a throaty sound, but without that "june bug in a lampshade" kinda sound. So, it's a hit or miss deal with 6 cylinders.

-Sam.

culp7 · 10-22-2009, 03:44 PM

come on i know way more of ya'll got six bangers

threeonthetree · 02-01-2010, 09:10 AM

I've got a stock manifold with a rusty downpipe that leaks where they connect and no muffler.

vasquezmrysvll · 02-01-2010, 12:46 PM

mine is a 250 with stock manifold,Rusty pipe to a flowmaster 2 chamber. needless to say its LOUD! i cant get the thing to run right, so a FI small block may be in the works.

silverstreak · 02-01-2010, 01:18 PM

Just a word of caution. If you're planning on going with dual exhaust manifolds or headers, you'll need a way to keep the intake manifold heated for good driveability, especially in cold weather. The factory does this by bolting the intake directly to the exhaust manifold, where as the headers and dual manifolds are physically seperate. I bolted a plate to the bottom of my intake and ran lines for engine coolant to warm the intake. This works well after the engine has warmed up, or if you live in a warm climate, however it is very cold natured now. Don't get me wrong, it made a big difference in power, but now I don't even pull out onto the road until the temp gauge reads 180. (maybe a lesser of a problem if it were an automatic) If I were to do it again on something I drive regularly I would have split the original exhaust manifold and modified the original intake to accept the three carbs.

OJ1988 · 02-01-2010, 02:09 PM

Running pacesetter split header, pipes into glasspacks turning out in front of the rear tires.

Sounds more like a stock v8 than a split six to me. I think the pipes need to be longer to really exploit the sound.

culp7 · 02-01-2010, 04:24 PM

Where did you get that pacesetter split?
