Common questions
Will these slip-ons fit my 2023+ Sportster S model?
No, these Cobra 909 Speedster Shorts are specifically for 2014-2022 Sportster models. The Sportster S (2023+) uses a different chassis and requires a different exhaust system.
Do I need to get my Sportster re-tuned after installing these slip-ons?
Slip-on mufflers alone typically do not require a full engine re-tune. However, a fuel-air adjustment or a tuner can help optimize performance, especially if you have other engine modifications.
What kind of sound can I expect from these slip-ons?
The 2-inch constant-velocity cores combined with stainless-steel mesh are engineered to deliver a deep, controlled, and satisfying exhaust tone for your Sportster.

Beautiful sound, but LOUD!
I read a lot of reviews between this and the V&H Slip-ons and everyone said these were the "quieter" of the two but dear god these are loud. Ear plugs are required as can still hear a ringing after a long ride. So I installed the quiet baffle and I didn't notice a drop in dB. but the sound is deeper and in my opinion, sexier. I did get some popping sound so I paired it with the V&H FP3 and its gone now.<br /><br />Note: 2017-18 Sportsters require a gasket on the headpipe to create a seal which you can get from the dealership or aftermarket.<br /><br />The part number for the quiet baffle for this slip-on is: 9026.

Mufflers are of excellent quality. Chrome is beautiful and the tips are easily turned to the desired orientation. Fit is superb and the sound absolutely beautiful. Deep tone with a reasonable sound level at idle. They are however quite loud when on the throttle.

2015 Sportster 1200 Superlow
Love these mufflers. It gave me the deep rumble that I was looking for and is much louder. Even with my helmet on, you can definitely tell the difference. Install was pretty easy but instructions were limited and the font was very small. Luckily, I just found a YouTube video of a guy changing the same ones out on his Sportster and made j stall quite easy. Picture shows rounded tips but mine came slanted which I like better but you might want to update your pics if thats what your sending. All in all, if youre looking to make your Harley sound like a Harley, look no further than the Cobra 3.
