Awesome slip-on mufflers
359793
2015 HD Slim Fit perfect. Instruction make a little bit of sense. Heat shield's don't fit back on, but who care's they look great. Recommend using HD muffler collar, Best slips I have ever bought. This being my fifth Bike. Great for the money Arlen and MF came through on these. Nice throughty, but not annoying. Minor decompress pop. Use the lock tight that comes in box. 7/16 in the Wrench and socket size.

I can't say enough good things about these mufflers, the sound coming out of my camaro sounds almost like an exotic car. One of my coworkers compared it to a maseratti! The weight savings over stock is pretty awesome too. My only complaint is that the joints are mig welded, for this kind of money I expect tig welds on every joint.

I just had these installed on my 2018 Dodge Charger R/T Daytona.

Those of you who have a newer Dodge Charger V8 know you already have a great sounding muscle car with the factory exhaust system. These mufflers take that sound and crank the volume up to 11. From the moment I revved the engine to when I punched the throttle wide open on the highway, I knew I had made the right choice. I loved the sound my car made before, and I absolutely love the way the car sounds now and have 0 regrets having these put on.

If I could try to describe the sound difference, I would say the idle is a slightly lower pitch, it screams at WOT, and the rev in park is SO much more satisfying (and that's saying a lot considering how it sounds bone stock). It's the same sound it made before, but louder. Additionally, I now hear some crackling/gurgling when I downshift in sport mode which is a nice thing. There is no drone that didn't already exist, and one of the best features is that it quiets right down when you engage normal driving mode. You can easily hold a conversation with a passenger, listen to music and talk on the phone without the sound of your car being a problem.

TL;DR

LOUD! AWESOME! No drone. Get them, you won't have any regrets.

I replaced another brand of muffs with these and I'm very happy. The muffs are nice and comfortable and work great!

I ordered these to replace an old pair I had lost.  In looking on line there were a number of very inexpensive ear muffs that I was tempted to order.  I read the reviews and decided to buy this pair.  The reviews were good and they sounded like just what I wanted.  When they arrived I was very happy.  They are adjustable and come in men's as well as women's sizes.  I ordered the woman's size and they fir perfectly and can be adjusted smaller and larger as needed, I am an average sized woman.  They are very warm on my ears as well as the back of my head.  They are worth the cost!

Oh man...I just installed this with a custom 2.5" cat back on my 1993 Dodge Stealth and it sounds AMAZING!!!
Love this muffler - 5 stars all day.

These do a great job of blocking out outside noises and are very comfortable.  I'm no audiophile, so I'm not the best judge...but they sound great to me.  I really like the case it comes with as well.  The pink ones were $10 cheaper than the other colors!

I ordered these pipes on the 7th and received them on the 10th.  Very impressed since I didn't expect them for another week.  The stock mufflers were a bear to remove.  Finally WD-40 was used and life was good again.  These slip-ons went right on without a hitch.  They look and sound GREAT.  I bought them for my girlfriends Sporty and she is extremely happy.  I like it because I can hear her behind me and I'm not always looking in my mirror to make sure she's still there.  Now I just look cause she's hot.

My "notice me" loud muffler days passed long ago. I put this on my 1966 Ford Station Wagon with a 289 engine and single exhaust.  The muffler has a pleasant, low key rumble at an idle, walking behind the car there is no mistaking that there is a V-8 under the hood -- eighteen feet away...

Accelerating away from a stop in town makes just enough noise to catch a real "car guys" ear and make him look but not catch the attention of the general population or the local law enforcement officer.

Remember air conditioning was an expensive option when this car was built, the cars of this era were designed to be quiet at road speed with the windows down and keeping the interior quiet and free of resonance was a big factor in choosing this muffler. It delivers as advertised.

Crossing a concrete bridge or underpass with the windows down will encourage me to step in to it a bit just for fun but then back to cruising and blissful quiet.

To summarize, this muffler is no louder than the factory systems on some of the modern pick up trucks.  If you want to be noticed this is not the part for you.  However if you want a quiet cruising coupled with a low key rumble around town this is an excellent choice. One more plus -- like all Flowmaster mufflers, top quality (this thing is heavy) made in USA.  Happy cruising!

Great sound reduction with the foam inserts. It's really nice that they are remoldable. They are not super comfortable to wear for 4+ hours, but overall I'm very impressed and happy with their performance. Tested them out at the nitro fuel and jet car exhibition at our local drag strip.

Love these pipes, I ended up putting these on my 2013 Can Am Maverick XRS and it made it sound super aggressive and not to loud in the cabin.

Easy to install, great noise, not obnoxious sound, perfect size!

These things are awesome. I upgraded from ear plugs thankfully and these are so nice to use. They are slim enough to where you really don't catch them on much because they hug the hardhat pretty tight. In addition, they do an awesome job blocking out noise. I would recommend these to anyone.

These drown out sound quite well. I use them on my motorcycle and for shooting guns. Easy to remove and clean. Over time, the wear and tear can cause the in-ear piece to slip from the black housing. Not an issue, though. Getting a couple year's use is worth it. I'll definitely buy another pair.

Great sound and simple to install.  I did replace gaskets so it was easy as 123 and no problems.  Great product for deeper louder new bike, Harley's need a little help when new and these slip ons did the trick.

Absolutely perfect! Great fit and sounds AWESOME! They took about a little over an hour for me to install, but it wasn't too difficult. The result is a deep rumble with a big engine sound. HIGHLY RECOMMENDED!

Note: I recommend going to the dealer and buying the exhaust cross pipe gaskets instead of trying to re-use the old ones. Total cost is less than $8.
