Straight Pipe Or.....

[MontanaJack]

you might want to read up on current TX vehicle equipment laws.
no thanks to the kids straight pipping their daddy's truck and making a general nuisance around town, "there's now a law" requiring a muffler on diesel trucks. do a google for it.

If you really want to be straight piped without getting hassled by the man, there are a few things you can do. You can burn out the fibers in the muffler with a little diesel, if that's the kind you've got. Or turn it around backwards if it's only baffled inside.

I've never done this myself, so i can't attest to whether it really works or not, but I've read of others doing it and being happy with the results.

What ya need now is one of these. Sweet sounding, put it one way and it's kinda loud, put it the other way, calms it down, but still sweet. When the cups face back (1st pic) kinda whistles. There 3-1/2" in and out, 12" - 14" long Got one on my PSD. Found it on ebay 3-4 yrs ago.

lol, you posted this on my timing thread too...
was that the incorrect thread?
my muffler is a turbine

Got a 3 inch downpipe mated to a 4 inch straight pipe. Using the 088 as a muffler. Working well

Straight pipe(3"), but have a turbo, so its not that loud.

2 1/2" pipe with a 36" hollowed out glasspack, not very loud till you get on it!! Kids and love it... Lol

 

[jhenegh]

3" (2 7/8") Banks downpipe to 3" until the rear axle and then a 45 degree 4" angled dump after the leaf springs. A turbo counts as a muffling device in Indiana, and this thing isn't very loud with 15' of smaller diameter pipe pipe and a turbo

Thankfully nobody voted for stacks.

I'm currently running a 3" straight-pipe that exits in the factory location. I scavenged it off a truck that was being parted out; I don't know it's original source.

I have a Diamond Eye 5" system that will be installed someday. It has a straight-through muffler...I like the sound of a straight-piped truck, but I also like the idea of keeping unwanted legal attention to a minimum. I may accidentally install the muffler backwards; we'll see how things sound both ways

install it on 2 v-band clamps, then you can swap em easily!!

3" DP to a 5" Diamond Eye system over the rear axle for a 94-97 OBS Powerstroke. No muffler, a little cab drone, but it sounds solid with a turbo truck. Whistles Dixie...Leeland can vouch for it.

Have the same setup with the 6.9/Banks gated Sidewinder and now the 12v Cummins.

I'll check that out. I like the way my current set up is it's bolted in sections so I can remove the muffler until inspection time. Is the factory piping bolted are is that something the Po did?

i just run a louvered core three chamber muffler on my trucks. it cuts out the 2800rpm+ "bark", but still in noise compliance. Do be warned, this "law" is more a tool for small town LEO's to ensure compliance when someone complains of a noisy truck and are able to report a lic# with the complaint. This will give the LEO some room to make the offender's life difficult. BUT....if a visual inspection reveals a muffler, the LEO then needs a meter to quantify a DB value on the loud exhaust.
see below for photo of my typical muffler on my trucks.

highjack!
do you have some sort of hydraulic equalizer for your dual rams towcat?
on log truck,they simply joined the lines with a basic T but the rams don't work evenly at all.can't dump a load (well can't dump yet anyway until i get the whole system welded up better than they did to this one) i tried searching for such a device but no luck.there must be some type of device to make them work evenly right?

 

[Can30Diesel]

Three inch straight pipe through a cherry bomb that dumps out just before the rear passenger side tire with a N/A engine.

Yes, it is loud.
