So I put V&H Dresser Duals on my bike, I checked for leaks at the header, crossover pipe, and both slip-ons. I used a vacuum hose (as a stethoscope) and I couldn't hear crap...but it was my first time using this method. I have heard it will be very obvious when using the hose, however I wanted to verify before I waisted my time buying hippy incense sticks to smoke test it.

Reason I ask is I'm getting decel pop (GO FIGURE!?)

haha, thanks guys.

 

Decel pop is probably a tune issue. What tuner are you using?

 

Tune?

 

FP3 using "Dresser Duals With Twin Slash Cuts" map

I'm running DD's with 4" Rinehart's in reality but figured that was pretty close.

 

Did you seal the pipe seams/joints with HT silicone (e.g. liquid copper)?

 

I was not going to go that route unless I had evidence of a leak. I'm not convinced yet.

 

Here is a clip, even at idle the right side seems poppy no?

did you try running a couple of auto-tune sessions? Also, FP3 has a decel pop contol setting. After a couple auto-tune sessions-try the decel pop settings in FP3 - there are 3 settings; low, medium and high depending on how much popping your getting.

 

You say you checked cross over pipe. I thought they are true duals?

 

Dresser duals have a crossover pipe.
