There is no warranty on exhaust pipes and mufflers with regard to any discoloration. Discoloration (bluing) is the result of tuning characteristics, cam timing, carburetor jetting, overheating, etc., and is not caused by defective manufacturing. See the CHEMS/LUBES section for products that will help prevent or remove bluing.

Installation of a new exhaust system may change your motorcycles fuel-air mixture requirements. Please consult the exhaust manufacturer directly with questions regarding any modifications that may need to be made during, or after, installing their product. If a jet kit or fuel processor is recommended, see the FUEL/INTAKE section

The Air Resources Board (ARB) does not permit the use of aftermarket emission-related parts that alter the air/fuel ratio of an emission-controlled vehicle. Due to these legal restrictions this part cannot be shipped to California.

Exactly what I was looking for.
I was looking for a set of slip ons to give my Fat Boy Lo a little more throat without having to remap the computer and these were the perfect answer. In less than 45 minutes I had them on and WOW they sound great. And another big + is the baffles can be modified if they're not loud enough for you. Couldn't be happier with the pipes and DK's price and dellivery.

Great Buy!
Save your money on Screaming Eagles and buy these! You will not be disappointed and they are WELL worth the money. The rumble is nice and won't bother the neighbors. Once you jump on the throttle is where they shine. Nice roar but not obnoxious and the finish is first class. Adjustable tips are the cats meow and really complement my Road King.

Sassy, not raspy
Installed these pipes on my 2017 Heritage. Went on easily, with exact tolerances. They look great with a deep chrome. They have a deeper, throatier sound than the pipes I have used in the past. Cruising down the road and they quiet down, don't have the blast in your ears for miles. Touch the throttle and you know they are there.
Dennis Kirk by far had the best price and I was not disappointed with any part of this transaction.

These are very High Quality...When idling they sound like a Muscle Car but when you turn the throttle the mufflers come alive...Awesome sounding! They look great on my 2012 Dyna Super Glide Custom. Thank you Cobra and Thank you Dennis Kirk.

Nice sound
Easy to install. As not loud as I thought, thanks God. Sounds stronger then the original pipes. But I think I'll need a new air filter,...cause my 2012 Fat Bob seems have lost a little bit of its torque. Reccomend to anyone.

Do I need a tuner with these?
A shopper on Aug 27, 2017
BEST ANSWER: It isn't always necessary but changing any part of the air/fuel mixture will pribabky need adjusting. A good fuel management system (one that learns and is user friendly is a good investment) and well worth it. No more having others charging you for tuning.
is the price for two ?
A shopper on Mar 4, 2017
BEST ANSWER: yes it is
