A little backround - The stock pipes were too quiet, hot, and restrictive. I did a 107 upgrade and went to D&D 2>1 Fatcat with quiet baffle. My main goal was to extract as much power out of the bike and chose the Fatcat based on that, thinking "How loud can it be?". At idle I like it. But on the highway, where the bike lives basically, I'm finding it too loud. That and my fasteners all need re torquing after a long ride.

So the question is - Is there a quieter pipe out there that won't strangle the power out of my bike?

Thx in advance

(yes - did searches ad nauseum before buying, but here I am)

 

Supertrapp supermegs 2:1. Im running my 103 with 28 discs, and have gotten the most power from these. I also run 10 days straight going cross country and wouldnt have it any other way. Thats me though? Ive tried Crushers and MO's, they were too loud or hp robbing

 

+1. I love the Supermeg. I'm running 20 disks. I may add some disks for alittle more sound. 20 is very radio friendly though.

Supertrapp was provider of the original Screaming Eagle pipes until they lost the contract/Harley outsourced to China/or whatever happened.

Anyway, just a bit louder than stock and you keep the power.

 

Supertrapp again,

I have supermeg slip ons on the 09 and run 16 discs rt, 9 left.

had supermegs on my '95

have had a supermeg 2/1 on the fxr since 1990, 24 discs.


when stacked, the discs force the gasses through a 360º "W" shaped baffle ( in profile) where the width of the baffle changes. this filters out high frequency noise.
low frequency noise is absorbed by a conventional packed baffle.

If too quiet, partially open end caps can be substituted for discs.

the 'closed course' end cap = about 10 discs ( in terms of flow)

the nightstick end cap = about 9 discs.


the made for H-D nightstick and fatshotz are very similar to the supermeg and can be altered ( end cap and discs) to perform similarly

not all supertrapp/ kerker pipes use the disc system for tuning and that would include previous to 2010 screaming eagle part numbers.

Wow! Thanks. I didn't expect such unified feedback. I was just checking out their website. Nice looking pipe.

I'm guessing I'll have to retune if I do a switch even if it's from one 2>1 to another brand of the same thing.

 

i probably wouldn't bother with a retune,at least until u get the pipe dialed in,even then if it runs good ?. add me to the list open end cap 10 discs.

 

one tip b4 ever mounting the pipe remove the screws that hold the discs,cover with LOTS of high heat copper antisieze.
