Great Pipes
I did not like my factort pipes so I went with their recommended upgrade pipes by after riding for awhile was not impressed. I purchased the Cobra pipes and I cannot say enough. Shipping was quick and easy. The pipes were easy to install. The finish is perfect. And the sound is fantastic. You get a deep rumble and it really talks if you want it to but you can slide throufg town fairly quiet if you choose to. Better on your neighbors too. I love and highly recommend these.

Excellent choice
I wanted a nice sounding muffler that didn't blow my ears off and this was a great choice. It sounds really nice and is ,loud enough to be heard but not so loud it deafens you.

Great muffler. I was thing of selling MC. I love the way it has improved performance and took out 99.9% of the vibration out of the ride. Keeping the MC. I had Vance & Hines on before. The cobra is GREAT. LOVE it. The guys at Cobra and Dennis Kirk where great. I can't say enough about the new muffler. Best money I have spent yet. No more pop on deceleration . Great low rumble.

Okay, here's the deal with the Cobra slash down muffler. Sound is definitely improved over stock. HOWEVER, I then went a few extra steps. There's a guy on eBay who sells stock HD pipes with the cat material removed. He cuts them open with a torch, removes all that waddling and welds it shut again. Cost me about $150. The sound and response got even better. Then I took the muffler off and removed the core and pulled away all the wedding there, too. NOW the bike sounds and runs great without being piss the neighbors off loud, and it cost me hundreds less than a full system. Probably a lot more of an answer than you were looking for, but I've found there are no silver bullets out there. If you want a lot louder than,stock, buy a full system, but then you,still might find yourself removing the wedding from the core of the muffler. Good luck!

Made it much louder
II had a quiet factory fitted exhaust that you couldn't hear too well when riding-this totally solved that problem by making it much louder

Do I need a tuner?
A shopper on Feb 26, 2017
BEST ANSWER: You will only need a tune if you run both a slip on and a cold air intake. You will experience some extra deceleration popping but that's all.
can i hear it?
A shopper on Jul 5, 2017
BEST ANSWER: Great upgrade from stock exhaust. The COBRA Slip-on gives you the best of both worlds, very quiet at idle and when cruising yet loud enough sound when you bring up the RPM's. Sound is not a deep rumble but more like a crisp raspy crackle. A riding buddy has the same exact same Harley Dyna model with the Vance & Hines 4" twin slash which produces a very deep classic rumble right from idle and just keeps getting louder as the RPM's go up. The COBRA is about 75% quieter at idle and then catches up at the top end of the RPM range. Two very different sounds from the exact same Harley 103 cid. Both the COBRA and Vance & Hines will lean out the bike and caused decel popping and shift popping when hot. Motor will also run hotter without getting a tune. You will need a stage 1 or better tune if you also change the air cleaner and/or de-cat the head pipe. ( I just had the ECM re-flashed and could not be happier. Bike runs cooler, big power increase and exhaust sound has gotten a big louder after 500+ miles since install). Total time to install was 15-20 mins.
