You are on your way to dual exhaust on a Dyna! What are you plans for supporting the cross-under and the left side? Also, the cross-under can be pie-cut and re-welded so the left side will mirror the right side.

Thanks AFMM3,
I am planning on getting the hard bag brackets on and then heating the pipes with a torch to adjust their location. As far as the cross under pipe I will fab up a bracket to attach it to the frame under the bike. I'll just have to play it by ear. I put a video on you tube so ya'll can hear how it sounds. She has a nice rumble

I have been wanting a 2n1 fishtail but I really like what you have done ( still needs fish tails or rocket tip ) but that's just my opinion . I have a Dixie muffler of my flathead im thinking of trying to fit to mine . my problem is my header pipe is 2 1/4 od

Here is what mine sound like. I prefer a smooth deeper tone and the 2 1958-78 muffler fit the bill. I got the original cross-under clamp from an ElectraGlide and attached it to the rear engine isolator with a homemade bracket. Did you stretch the collector to get the cross-under in the best position? I had to stretch mine 3 inches which is exactly how much longer a Dyna/Softail motor/transmission assembly is than an ElectrGlide.

AFMM3,
Your bike sounds awesome. I go by the mantra "loud pipes saves lives." I didn't need to stretch mine. The system is off a 2012 SG. Maybe the newer models are a little longer. Everything just fits like it was made for my bike. The only thing I had to do was cut off the original mount from the catalyst and make a new one. Then weld it so it would attach to my mount from the V&Hs long shots. With the pie cut on the cross under pipe everything is perfect.

I have been thinking about this true dual setup for a very long time. Now that I have the bags on my bike I am going to contact V&H to see if they will just sale the parts of the true dual system they offer for the Switchback. I am asking only for the header pipes, crosspipe, heat shields and trans bracket, no muffler pipes or fender brackets. I have talk to them about just buying parts of an exhaust sustem before and they would sale, so if they do the same here I would imaging that the cost would be well below the $1200 they want for everything. I know I could just get the Touring exhaust and modify it, but I don't have the metal working skills to do this. I figure it can't hurt to see what the cost would be. If its cheap enough, I would go this route and then add some fish tail exhaust/mufflers to the header pipes to achieve a look I am after.

These header pipes


With something like these ends.

Speed bumps around here would rip that front header pipe off in a NY second.

carl'69 im with you on ripping pipe off , plus I don't like the ideal of the exhaust being right next to oil pan on air cooled motor

There is that, as well. I love the "fat" vibe, but I'm not trying to cop the full-deal Dresser thing. I'm chasing more the stripped down, pissed off '70s FL vibe.

I never noticed that the V&H was so low on the right side. On mine, the transmission bash plate is still the lowest point of the bike.


I stretched the collector on the right side 3 inches so it would cross-under in the correct spot and I could use the stock cross-under bracket. It normally connects to the transmission pan but I made an adapter setup to connect it to the engine portion of the rear isolator (engine mount). In this picture you can see where it exits on the left side. Leveling the left pipe in relation to the saddlebags was critical to a stock look.


I originally suspended the mufflers from the saddlebags but was wearing out the rubber isolators too quickly. I connected them as a test using short Pitman arms but it started transmitting vibrations into the bike. I then committed myself to making a bracket that would support the entire exhaust system from the engine assembly.


The bracket worked fine and allowed me to ride without the saddlebags if I wished. I was adding fishtails to the mufflers and since I would need clamps, I used this opportunity to stiffen up the left muffler by running a polished aluminum tube between them. This was what was finally need to create a complete "box" to the exhaust system. I could probably get a few guys and lift the bike off the ground by the mufflers if I wanted to. No vibrations from the exhaust and I have done two cross-country trips without a concern from the exhaust.


One thing that I have noticed lately, almost no one will ask about my bike for fear of sounding ignorant of old bikes. They stare but will not ask questions.
