i searched over at the Ryder site and i keep finding the Nelson 5" In/ 4" out but i sware there is a 4" in / 4" out 40" muffler and a 4" in/ 4 out muffler at 51" both are straight through mufflers but i cannot for the life of me find them.

Im going with the 40" most likely, (though the 51 is tempting) that 40 should get me where i want my 23" straight through 4" Drones too much with a heavy load. i will be adding sound deadener but a muffler swapis easy for me right now.

thanks

Dustin. I run the Donaldson M085171, it is a 40 in 4 in and out straight thru pipe, there are pic in my gallery of the set-up, sound great also. pick it up thru CFL exh. warehouse,

 

Check out my gallery, got the part number for my 40" Nelson there along with pics.

 

I have the 51" Nelson. The part # was 86131M. It was straight through with no center disc like I found on the Donaldson. Stayed as quiet as stock with the cat still on. Fisherguy is where I got the idea of fitment.

If you want a nice mellow sound, but not much louder than stock, go with the 51" nelson. My son has it on his 03. I have the 40" on my 05, and under load up hills, or when you step on it good, it's a little too loud for me. I prefer the 51". I bought both at Alberta Cummins, and the prices were excellent.

 

im ordering the 51" nelson just need to find the right place

 

You won't go wrong.

 

I've been thinking the same thing. What size would a direct replacement be for an 03? 3.5" or 4"? Do they come with hangars for the stock location?

 

They do make a 3.5" 51" muffler. I put one on my 2nd '03 before changing it all out from elbow on back. I'll see if I can find the part number for you.

Here's a link to the Nelson mufflers:

Look for Part: 86113M, when you find it click on the part number, looks like a 51" muffler with 3.5 in and outlets:

the above number was used. i have a 4" turbo down system muffler was $78.94 to my door. i am also installing an ATS manifold on friday so im pretty happy with any deciple decrease i can gain without disrupting exhaust gas flow
