Excellent service!

Just the sound I was looking for deep rumble at cruise. Can hear music without adjusting volume, great power.

I'll be honest, I always wanted the V&H OS 450s; to me they've always had "THAT" HD sound. Unfortunately, that sound comes at a price that my budget just could never justify. I'd heard that Cobra makes a good pipe but I couldn't find anyone who was actually running them so I could hear them live. Also, these slip-ons are pretty new so I couldn't even find any sound comparison videos anyplace. They looked awesome in the pictures and the price I found couldn't be beat, so I finally decided to just bite the bullet and buy a set. I can't say enough about these things. They have a great bark when you go to the whip, but they smooth out beautifully at speed so you can still hear your passenger and/or the tunes. Do they sound as good as the V&H? No, the OS 450s still sound better (IMHO); BUT NOT $250 BETTER! Throw in their lifetime warranty and I recommend these pipes without hesitation or reservation.

After doing my research I picked the cobra 909 slip on couldn't be happier. Easy to put on ( took 30 minutes) and it's the sound I was looking for.

very nice mufflers but too loud for my application

Low rumble sound, not very loud. Sounds good but if you're expecting loud you won't be happy. The wife loves them because we can still have a conversation and still hear the music. Really nice looking pipes too. Well worth the price.

I put them on a 2017 Ultra limited low and the install is very easy. The Rumble & the sound I was looking for was dead on !! Very happy with this purchase.
