If I pair these with a new set of Cobra True Dual headers, do I need to purchase some type of fuel management system or race tuner? 2005 Road King.

Yes, and this is the exact set up I have on my 2012 FLHTCU. I am using Cobra's Fi2000r EFI Tuner. It was an fairly easy connection and Cobra had great instructions. Looks like you will need Cobra's part number FI2000 #692-1600. These list for $249 but can be found cheaper online. Check to make sure part number fits your exact year/make of Harley. Good luck,Jeff

Not necessarily but I do think that you need to have your bike Dyna tune so your pipes will be in tune with your engine, and a stage two air cleaner

if it was just slip-ons no, but full headers, yes..try the Harley forum for xtra info

Yes they will. Just installed on 7.19.2014. I attempted to install myself but ended up paying someone $400 to put on. Header Nuts were a pain in the A** �They do however eliminate one catalytic converter on either side. SOUND AMAZING !!!!! Highly recommended !!!

Yes. Standard throttle and idle cable set up. I'm very happy with these grips.

Put An Aftermarket Intake, Exhaust, And A Performance Chip On And That Will Be Crazy! Or You Could Either Supercharge Or Twin Turbo It.

Yes, that should work. I did the same to my differential and two races later everything is fine.

I didn't have too do any thing to mine, I'm told the newer bikes are more tolerant too small engine mods.... all I've put on mine so far is the K&n; RK cleaner, and some aftermaket slip on mufflers , and it runs great / lot better than stock..... no complaints at all, and still has that stock appearance. Hope this helps you, good luck K.L.

Yes they will bolt up to the stock exhaust. To get the most out of them contact Cajun B pipes and get a set of b pipes from them. If you have no smog go with the catless B pipes and you will see serious gains. Also do not forget that to install these on a Titan or Armada you need to get Uprev tuned to correct your AFR's after installation.Another tip is use the opening closest to the collector or you will throw a code.

Hi Vic,Yes you will need a race tuner to install this exhaust. I do have them. You can call me for more info.Thanks,Dave870-580-0940

If you own the VQHR motor this not the correct kit you will need part # P3507-DUAL0 which is the dual setup.

The carbs will work but they do need to be jetted. They are jetted far too lean even for a stock motor. Some carbs also have bad threads from the factory so you should disassemble and inspect before you install

You will sacrafice fuel milage, mine went from 42 mpg to 38 mpg. But worth it to me. I've made mods to the engine and changed exhaust 2 or 3 times and the Auto-tune keeps it running at peak performance. No more costly dyno after mods!

Hi Brody,As a rule the answers is yes to the Turbo Boost and *Fuel Pressure (*May require EAS add-on). I would need to know your application to be 100% sure, the PID's readings do change on some applications.Hope this helps, feel free to give me a call if you need more information,Thanks,DaveMONSTER PERFORMANCE870-580-0940

Putting these on will definitely change your fuel air mixtures. They eliminate a lot if back pressure. You should absolutely change your air cleaner to allow a greater volume and thus you will need the fuel management to make appropriate adjustments. Dyno if you will but definitely will need an adjustment to run properly.

go to the diablo website- I have asked the same question since I got it. everyone usually does the big 4 ( tires size- throttle boost 20%-canned tune (diablo tune)- firm shifter) some disable auto upshift- where you have to manually put into higher/lower gear. other than that, thats about it. no one I know or I have asked could answer the WOT fuel/spark/indepth numbers.

Most require the adapter plate and stud kit and gaskets ,you might have to fab a throttle bracket amazon has a deal on all of it when you buy carburetor from them I did all at 1 time no problems

These pipes have great sound... I installed them without tuning or a filter replacement, and I did get slight "popping" on deceleration. No issues at all with acceleration or idling, but I've ordered a K&N; filter and a fuelpak. My recommendation would be to tune it and do the filter change.

I had to tweak the carb on my 06 Sporty. If you have EFI then it too will need some tweaking. And I installed Screamin' Eagle air kit. More power instantly and way more responsive. If you do one you gotta do em all.
