Oooooh Yeahhh!!! A very BIG THANX cobra people... I can actually say, this buy is VALUE FOR MONEY. My Buke is so ALIVE again. My Fatty GROWLS like a hungry Lion. It sounds so so so good cant explain. I love em


Workmanship and appearance are to the standard I expected from Cobra. However the mounting is off to the point as where none of the mounting holes or brackets line up without drilling new holes and the rear bracket is positioned as where it would only be possible to get one of the mounting holes in the Cobra mufflers . ( FLSTNSE-110 Screaming Eagle) Soft tail-Deluxe.


There chrome race pro muffle was easy to change out and was exactly what I was looking for. I get many complements.


great sound, and fitting them was easy


Bought for my 16 Breakout. Woke the bike up. Still have baffles in and don't think I'll take them out as they are plenty loud. I would recommend.


It took about 2 weeks to arrive because Cobra was out of stock. The fit was easy and was installed in less than an hour. The finish is great. My only complaint is that they are way to loud for me and Cobra doesn't make a quiet baffle for the RPT slip ons.


It's all good so far!really like the rumble,noticeable increase in pulling power in 5th and 6th ,,, wife thinks they are too loud,a slight increase in idle speed,I have the fi kit and once i get that and the Ness filter on im sure the 96 inch twin will roar,, fit was perfect! the hardest part was getting the factory front muffler off, ordered new clamps but didnt really need them,the fit was perfect,, definitley fast and furious! really nice machine gun timeing when cruising sweet rock and roll music to my ears! KMAN


Had the OEM Harley pipes on which really didn't sound like a Harley. The great thing about the Cobra pipes is you are in control. If you don't want to wake the neighborhood you can keep your RPM really low and quietly sneak out of the neighborhood. Conversely, if you want to let them know you can give a slight rev on the gas and they'll know you have new pipes! Same at stoplights..and, every time you take off from a dead stop - you will know they are not OEMs and so will everyone else. Good throaty sound. Definitely a good buy.


I shopped and shopped, looking at so many options. And reviewing the sound of my options on youtube and various media outlets. I do recommend checking out The Vance and Hines and Cobra apps, to get an idea of the differnt sounds and tones. I ordered these and love them. Easy to install, took about 30 mins and SOUND AMAZING!! Great idle tone and deep throaty sound at "off idle". I highly recommend these to anyone. I ordered these from J&P Cycles on a Sunday and had them on Tuesday! Fast and awesome shipping for being free! I was shocked.


easy installation and added nice sound to bike.


Great exhaust alternative to replacing pipes. The Slip-on are exact fit to factory. Had installed in less than an hour. Nice rumble like a Harley should have but not too loud.


Great product, well-made and sounds mean! Install was pretty easy - took about 20 minutes. Still fine tuning it with V&H FP3. J&P Cycles rocks! Fast shipment and great service!


Good deep sound but only if you like loud


I've already heard these Slip on's on a friends bike, They are very satisfying to the ear, Probably more so on my bike as my current stock pipe's have blown the packing out around the inner baffle and it sounds like true Death X_X Final thoughts Grate delivery time As well as packing style. 1 Con no Cross over gaskets :(
