Awesome custom exhaust....sounds like a beast...luv it!

Sounds great and i am like RD with the length. Just watch the tight spots. I see machines come in all the time with the metal screen torn back in both directions, but i love the sound.

That sounds good Dave , Is there a reason why not go straight out ,Be less compartment heat .

Don't take this the wrong way, but I think you almost[ have those mufflers sticking out to far. It looks great, sounds awesome, but I would be afraid of mashing the mufflers back against a tree. If it was mine, I would want the mufflers pulled in maybe another inch. NOT trying to be critical, I would just hate to do damage to something that took that much effort, and looks that good. RD

The reason that I moved both of the RLV mufflers out side of the screen and in board from the out side rubber body band , because I was concerned about the hot exhaust gases discolouring the out side of the tub.

Roger that.
I'm also interested in how you arrived at that length of pipes? It looks cool, but is there a science to the madness?

Is there a reason why not go straight out ,Be less compartment heat .

I called Performance V Twin and they told me that on a 23 hp , brigg's engine ,running 1.25 inch pipes , each pipe needed to be at least 28-32 inches long. Another friend of mine used an exhaust pipe formula on the web for a 23 hp motor running 1.25" inch pipes, and he said that each exhaust pipe needed to be at least 28 inches long for best performance. For a 23 hp Engine running one inch exhaust pipes , each pipe needed to be a minimum of 18" inches long. When I used to ride Harley's I was always told that a longer pipe will give more low end torque and shorter pipes, up to a point, will provide better mid range and top end performance. Because of the restrictive space that you have to work in on an Argo, I could'nt build a 28" inch long pipe. With a few bends I was around 40-42" inches for each pipe. Straight out of each head and with bends on each exhaust pipe , I wanted to make each pipe run close to parallel. My longer pipes also give a more mutted tone. Not raspy, but just enough rumble to suit me.

GREAT JOB, DAVE!!!!!!!! I love it.

Thanks. Did'nt you tell me that you're going to build another set of pipes for your Hustler Bigfoot ?

Sounds really good Dave, I hope you can have it ready for the Mud Nationals. Do your pipes have a flex joint or some kind of soft mount so they can move separate from the engine? I know the Argo's engine is mounted fairly solid but I think you'll get some movement when you hit the throttle. If your pipes are frame mounted solid after the engine heads, the pipes might crack.

I mounted them solidly to the perimeter , box tubing frame that supports the dash and upper front tub. If you watched the two video's that I posted you'll see two bolt heads on the aluminum pipe bracket cover. This is how the pipes are supported. I was also concerned about not making either pipe with a flex joint, but I also have a winch plate. The winch plate and winch support tubes are made from a bent peice of round tubing that fits through a bracket that secures to the front tub, and each leg extends down on either side of the engine and then bolts to the frame. Because of strong bracing of the winch supports , I don't see how I will have enough flex to crack either pipe. Measuring from the outside of my Adair tracks, my RLV muffers are mounted inward about three and half inches.
