great...so some say yes, some say no...hmmm

 

My partner is running a DIY 2 x 1 on a SE Stage II 95 CI FLHTPI.

We used the LS Muffler and works like a charm.

Bike will run with most anything out there

EFI is the MM, not the better Delphi.

Go Ahead, give it a shot.

Good Luck

 

DIY @ the top of the forum page.

 

everyone's saying left side muffler...i've got wild pigs w/2" baffles...they both look identical, would it make a difference?

what size Chevy Freeze plug?

does the type of EFI matter? it's an 03 King...i think it's a delphi

 

Aftermarket mufflers do not have a catalotic converter

1 1/4" Freeze Plug

EFI is EFI, does not matter

Good Luck

 

i did exact oppisite i cut down tube installed freeze plug in top of pipe& bottom of pipe use a hose clamp to hold it together true duals for anout $2.20 plus my custom baffels in the stock slipons

 

stupid question...true dual or 2 into 1, if it seems so "easy" to just plug the pipes, why doesn't everyone do it?

 

I cut mine off, gutted the muffler (for better flow) and welded in 2" straight pipe in the center of the muffler. PCIII, runs, and sounds great!
Look no pipe

 

I think we established yesterday that only the '06 had the catalytic muffler, and it is only in the right side muffler. If you look down the inlet end, it looks like a coffee strainer, the holes in the screen are so tiny.

stupid question...true dual or 2 into 1, if it seems so "easy" to just plug the pipes, why doesn't everyone do it?

One factor is the unequal length of the stock head pipes. Many of the aftermarket 2into one's have equal length head pipes.

 

In answer to your question YES I have done the conversion.
I cut the left header outlet and welded a plate over the gap and install a sensor bung, an easy job to do if you have a mig welder or have someone local to perform the work. If you look inside the horizontal part of the header you will see that the vertical part of the header extends into the front pipe a small amount, I used a die grinder & file to remove the pertrusion hoping to ease the flow of the front exhaust.The actual angle of the rear to front join isn't optimum but what difference this makes I don't know.
I install one of the D&D Police interceptor mufflers that I was already using on the true dual set I was running.
Performance wise my seat dyno told me that there was a gain in torque 2000-4000rpm which was what I was looking for.
I did this change to see if I would like the 2into1 sound and if I would be happy with the single pipe look.I obviously am happy with both as I purchased a Supertrap supermeg 2into1 unit and am very happy after to many exhaust changes.
If loudness isn't an issue the Fatcats are a popular choice where as the ST's can be tuned easily for loudness or quiteness ( quiteness being what I was looking for )

Hoping this helped
