Yes... Puzzled me at first... But it appears these are mufflers with electronically controlled valves in them.

Apparently explains the cost...

They don't really appeal to me... especially for the money. Plus, I'd have to know more about how the performance impacts are delt with (if at all) in regards the valve position and the Map/Tune.

 

Another vote for the S&S. They're louder than stock but not douchebag loud, and I think they're the best looking slip-ons. Had 'em on my Fat Bob for five years now.

 

Glad to hear guys like S&S Grand National Slip-Ons. Included them on my Stage II build happening now. Anxious to test them out in the spring.

 

The S&S are no doubt quality pieces... EPA/CARB compliant and all. If memory serves, sound clips and reporting from forum members suggests they would probably meet the OPs performance/sound requirements. However, for me they probably wouldn't be a pick. I just don't like their looks for a vintage/nostalgic looking bike like the Heritage. I don't care for their square/or slash cut end caps for this application. They would look too modern/contemporary/out of place on Heritage in my mind. The American Custom option just works better in this case - at least for me. Plus the price... The American Customs are hard to beat. Those S&S Grand Nationals are pretty pricey (well over $1K).

 

Yeah, the $1k price for S&S GN includes high flow cats, w/o they're around $500. I wanted cats, kind of done with the days of stink and fumes, after growing up with 'em.

I agree, I don't care for the mod bike look of the S&S GN pipe ends either, but hadn't heard other similar sound options until your post just now. Hadn't hear of American Customs. Too late for me now - already dropped the $1k and putting pipes on.

 

I had a manual exhaust cut out on my old car in the 60's. Think it is like 19.95 from jc whitney

 

Haha, hilarious. That's exactly what I'd like to avoid. The "douchebag" sound. I can't stand it. I almost went with the S&S GN pipes actually. Ended up pulling the trigger on the American Custom modified stockers. We'll see how they sound soon! Thanks.

 

Thanks. I completely agree on all points, at least on paper, which is why I grabbed the American Custom modified stockers. I *think* they'll fit the bill for me this time around.

Thanks to everyone for your input. Much appreciated! Hopefully I'll enjoy the American Custom pipes. Will let you know!

 

So if you are past warranty you don't need converters. They quiet the Harley sound a lot no matter what slip on or pipe you use. Biggest downside is that it has to be retuned and with something other than factory or SE Pro tuner.

 

Meh... Depends... but generally nah.
