I've seen posts in years past where the owner has taken the TH to a muffler shop or moto shop and had their pipe shortened. That could be an option. I don't think a TH is quiet and seems louder when I wear my FF helmet.

Well, maybe I'll see what it sounds like after getting cammed this winter...maybe it'll make a difference?

Sometimes different tunes can change the sound. But like already said, Thunderheaders are not quite.

As the previous two posters have noted, it is really the compression that’s going to increase the sound level. Get it bumped up to between 10 1/2 to 11, put in the appropriate cam, and it’s going to hurt your ears when you blip the throttle when it’s idling.

years ago I rode a hot rod dual carb Panhead with straight pipes- a local guy asked how he could get that sound out of his stock Shovel. I told him he would need to spend a bunch of cash & he decided that his sounded OK .

That's no joke, my hotrod 93" shovel run's 11.7-1 comp with a .600 cam and that thing will set car alarms off 2 blocks away just blipping the throttle during warm up. Has a serious crack to it running unmodded cycle shack 2" tapered pipes
