Cobra USA builds exhaust, sissy bars, luggage racks and bolt-on styling parts for cruisers and baggers, with a catalog aimed at the rider who wants a finished, matched look rather than a one-off fabrication. Its slip-ons and full systems are designed around factory mounting points for a straightforward bolt-on install.
Transform the sound and look of your 2004-2013 Harley Sportster with Cobra 3" NH Series black slip-on mufflers. These mufflers bolt directly onto your factory head pipes, delivering a tuned exhaust note and a cleaner, stealthier aesthetic.

Designed for 2004-2013 Sportsters
The Cobra 3" NH Series slip-ons are designed for Sportster riders who want a more aggressive sound and a darker, more intentional look. The durable black powder-coat finish offers a stealthy appearance that contrasts sharply with chrome components or blends seamlessly with blacked-out builds. These slip-ons are a direct bolt-on replacement, making the upgrade process straightforward and efficient.
Aggressive Sound, Stealthy Style
3-inch diameter slip-on design for a robust sound
Durable black powder-coat finish
Direct bolt-on installation to stock head pipes
Enhances exhaust note over factory mufflers
Clean, uncluttered aesthetic
Performance for Your Rubber-Mount Sportster
These Cobra slip-ons are specifically tailored for 2004-2013 Harley Sportster models, which feature a rubber-mounted engine. This direct-fit design ensures compatibility and a hassle-free installation process. While these slip-ons alone will significantly improve your exhaust note, combining them with a high-flow air cleaner and a precise fuel tune can unlock additional power and torque, optimizing your Sportster's performance for the street or the strip.

Common questions
Do these slip-ons require any engine tuning?
Slip-on mufflers alone typically do not require an ECM reflash. However, if you have other intake or engine modifications, or plan to add them, a fuel management system can optimize performance.
Will these fit my pre-2004 Sportster?
No, this part is specifically designed for 2004-2013 Sportster models. Earlier Sportsters have a different head-pipe configuration that these will not fit.
What is included with the purchase?

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.
