I own a 2015 road king with all the lean and heat troubles they all have. After a lot of research I bought S&S header pipes with a cross-over port, they look like true duals, and I kept the stock mufflers. Then I downloaded Fuel PAK FP3 for touring models other systems and loaded 2 into one with cross-over or similar pipe with stock baffles. I kept the factory air cleaner.The bike is a little louder than stock, sounds more like a Harley, all the decell popping and backfire is gone, acceleration is better, roll-on is better and the motor is a lot cooler, I mean way cooler, it runs a lot better, sounds better and all the exhaust and oil temperature worries are a thing of the past.I am a little lost with all this dyno talk, air cleaner swapping and mufflers. I have run a foreign car repair center for 43 years, raced top fuel dragsters, motorcycles, and snowmobiles both 2 stroke and 4 stroke with super chargers, so you may have guessed by now that I know a little more than the average gut about tuning, and building engines. If you do not go inside the engine and you have the same cams, pistons and compression, and you have the same cam timing and the valves open and close at the stock settings how does the engine flow a lot more air with a filter and exhaust pipe, if it does it is a small amount and maybe it will be a tad leaner but nothing note worthy.Vance and Hines knows all this and they have dynoed these motors and created a software download from these stock engines and put it in their product called FUEl Pak to make it very easy for us to basically get the dyno results without killing are bikes on the dyno, ever seen a bike on the dyno, you will not like your engine run like this. In my opinion this is the very best, fastest, easiest way to make your Harley what it should have been before the EPA tied up the manufacturer with their emissions standards.I spoke with Vance and Hines and even though I was using an S&S front pipe they were very good about recommending Fuel Pak for my application, that is good business to me. Bottom line, GREAT PRODUCT, it does what they promise for a great price.

Wish they were a little louder; however, they are outstanding slip-on's, Especially when combined with the V&H Power 2 in to 2 crossover power headers!!!

I'm very pleased with the sound of these pipes. They sound so much deeper than stock and they thump hard off the line. Yes, they are loud and if you put them on a bike like mine that has 5 gears running high RPMs at interstate speed, you may want earplugs (or the quiet baffles). That said, no one tailgates me any more, and on multi-lane roads all vehicles on either side of me give PLENTY of space. I installed the pipes myself and found the instructions to be satisfactory; however if you're not an aircraft mechanic like myself, teaming online video instruction with the paper should make it a breeze. The pipes are of very high quality, and come with all hardware for install. You may have to re-use some of your stock hardware and if your bike does not run O2 sensors, you will need to use the plugs provided with the kit. The matte black heat shields look great on my bike even though a lot of the engine bay is chrome. The price is very nice for what you get with these pipes, and after 800 miles since installing them, I'm still impressed every time I roll on the throttle. Great product, Vance & Hines; great price and quick shipping Motorcycle Superstore. I'm a happy first time customer.

I've had people try to tell me that this won't work "get the power commander V"... Well, I'm here to tell you, if you are changing your slip-on mufflers, head pipes, intake, or even cams, this thing works. I have had it on three bikes now and not only has it improved performance, I get better gas mileage, lower run temps, and no decel pop to speak of. Love the auto-tune feature.

Unreal- The pipes were easy to put on and when I come down the street, heads are turning. Vance & Hines- that says it all, you guys rock. Thank you.

love them, you know I'm coming and you know I went by. Great pipes sounds great and easy to install . Some decell pop with HD race pack and air cleaner added but not bad . I've had them for a year now loved them from day one and still love them now.
