Great Mufflers/Excellent Sound and Look
Had Supertrapp mufflers on my 07 Road King and loved the sound of those. Been looking for EPA mufflers for my Street Glide and read about the S&S MK 45’s. Dealer started stocking them and put them on a demo bike. Heard them on the demo bike and was sold. Great fit and finish and the end caps are top notch. Sound is excellent for those that want that deep HD rumble without being to loud. Can still hear the tunes while cruising or around town. Highly recommended. Added the HD SE pro street tuner to go with them and the high flow air filter that came with the bike. Great purchase.

Quality deep sound
I installed these on my 2018 Ultra Limited Anniversary. Chrome body with black end caps look great on this bike. The sound is quitter at idle than other bikes I have owned, but has a deeper richer tone when the throttle is cracked open. I think the sound is great, and S&S has once again come out with an awesome looking product that performs as well as it looks!

GREAT SOUND
Buy the whole system with the power tune headers way better than screamin eagles sound is mellow when cruisin but barks when you open it up.Deep rumble not tinny at all well made by a company that backs the products it sells.

Best muffler I've had so far
The S&S MK45 mufflers are the nicest mufflers I've ever purchased for any of my bikes. They are very well built using what appears top be a heavier gauge steel for the muffler body compared to competitors mufflers. It also has a stainless steel baffle and a unique muffler packing that should last for many years and miles. The chrome finish is flawless and the black end caps are a work of art. Stunning! The sound is amazing. Such a nice deep rumble and a good roar on top on my otherwise stock 103" SG. And if I ever want to be a bit louder I can easily remove the dB Reducers in minutes. S&S is a tried and true brand synonymous with performance. They didn't let me down at all. It's nice to see a leader in V-Twin engine performance step up and manufacture one of the finest exhausts you can find. I highly recommend this product!
