I have a set of these with rinehart slimline dual headers and the redshift 468 cam.They are rumbly and are a tad more raspy than i like with db reducers in. With them out they are more thunderous. I got the slimline header before they made them only available in the kits with cat the equipped mufflers. Thats the key for getting the harley sound we all like the cat dosent seem to affect power as much as sound. You can hear these mufflers echo when you rip on them further away too of course the air moving through with redshift cam is a big factor.
I've tried to make an update video as I've changed up a lot in this bike since I made this video, but my footage was not good. Cam, exhaust and more...
It became both once they burned in. I was pleasantly surprised after a few hundred miles, Krome Werks are great and definitely a step up from these. I have something much better being installed on the Matrix - big changes, will be picking it up this weekend and will make a video.
I’m in the 50 state pipe state too. By taking the DB reducer out did you lose any torque or power? What about tune? Is it too lean ? Are you happy with them ? I just got a ROAD GLIDE ST and these are the slip ons I want to use. Thanks
Mufflers came without db reducers so I cannot differentiate, however it did feel a bit less torquey compared to stock muffs. They burned it quickly and are now produce a very nice rumble and roar. I think the stock tuner has compensated for any changes in back pressure as they perform fine, or I'm used to the difference. Over all I'm very pleased with them and might miss the low rumble as I'm preparing a few upgrades, throttle body, cam and 2-into1 CMP custom made exhaust with tune. Upgrades should be louder and grumpier. :)
I liked them very much, however, I have since installed a custom built 2-into-1 long pipe from CMP Motorcycles as I had pumped it up for performance with a Wood 22ex cam and increased fueling. I think for the money, the S&S are very good slip-ons for the price.
