does that idle sound fine both sides? maybe I'm over thinking this one.

 

Did you try covering the slip on with your hand, to see if you can hear a leak? My cross over pipe on my dresser duals were leaking as yo can see in time you can see the black soot from leaking. Make sure the clamp is positioned right

 

How does this idle sound?

my sound crapped out on my lap top. Try a couple auto tune runs to try and get rid of the pop. Also check your headpipes to make sure they are seated properly. Also retorque the nuts holding the headpipes to the cylinders after a heat cycle. And finally check your crossover connection. The duals sound killer. I love mine with the OS 450s.

 

Mine sounds the same with the dresser duals, twin slash rounds and FP3 tuner. V&H said the difference in sound from the left (front) to the right (rear) is because of the pipe length for each cylinder. The front has more pipe and a couple of bends to go through to help even out the pulses but the right (rear) is a much shorter pipe and no sharp bends so its a more erratic sound. I did have an exhaust leak from the rear pipe flange at the head that was causing a more distinguished pop from the right side.

Hope that helps some.

 

Hey thanks, I was debating swapping out gaskets on that right side and seeing if it helped but maybe I will hold off.

You said yours popped due to a leak, was it a different pop than what is heard on my video? It tends to have that erratic tone to it on startup the most when it is cold.

 

Are you having "pop, pa-pop pop pop" on decel or a "POW PA-POW POW POW" on decel? If it's the 1st one and it's not very loud like backfiring, then that's a result of having a "richer" tune, which in completely normal due to increased fuel having a direct relation to increased cooling. Again, this is normal and you'll be fine. However, if it's the loud noises, then you have tuning issues and may be running a little lean. The best thing to do is just ride the bike and pay attention to heat, fuel economy and the overall delivery of power. If everything rides as normal and the bike doesn't feel noticeably hotter and fuel economy is still within 10% of normal, then it's all good. If it's running extremely hot and gas mileage is bad, then you should be worried. A short 10-20 mile trip with varying road conditions will be enough to make a determination. I have had decel pop on my bike since I did the stage ii at 261 miles. My bike now has 26,300 miles and I have had zero issues since. I'm running a pc-v with a downloaded tune from their site. Again...26k miles and no issues. Good luck.

 

Not trrying to hijack the thread but I bought what I was told were V&H Dresser Duals for my 08 on here from a member and they don't use a crossover. Did they add a crossover for 09 and up or do I not have what I think I have?

 

2008 is the old frame.

 

I get that, but some exhaust manufacturers make an under-frame crossover pipe for the 08 and earlier frame that mimics the stock 09 and later stock exhaust. I'm just asking if anyone who owns or has installed a Vance and Hines Dresser Duals exhaust on an 08 or earlier bike if it has a crossover?
