FLH Slip-Ons

[03rodeking]

I know that there is no definitive answer on pipes. But since there's 12 inches of snow outside, I can't hang out and check out other bikes. I have an '03 FLHR std, and I'm getting the MK 42 and AN Sucka. I'd like a slip-on that's at least 3 1/2", quality, enhances performance, and a low rumble (little louder than SE's).

I do have it narrowed down a bit. The list goes like this-

Bassani and V&H Classics are at the top, followed by White Bros, Hooker and D&D3 1/2. I don't believe you carry the Bassani, but any pro's or con's would be greatly appreciated. I know W-B are tunable as are the Hooker to some degree. I may install cams later, but believe the non-tunable slip-ons should suffice.

I'll do what I can to give you some input on your selections. Bassani, can't offer much, I have a friend with the stainless system on his XL and it looks and sounds decent. White brothers, is a popular choice if you plan to do a lot of tuning, it's a popular choice with people making lots of power beyond that I don't care for the look or sound of a disk type system. Vance & Hines, what can I say, it's hard to beat number 1, best fit, finish, and quality out there, however everyone has them, and they aren't tunable. Hooker is an often overlooked but very viable tunable slip-on. Most people will run one side on torque and the other to HP and this simulates a 2 into 1 system, I personally think this is a good choice. D&D is taking the exhaust market by storm, removable Baffles, great looks, and tough as nails chrome, I can't say anything bad about D&D so far. If their Slip-ons run anything like their 2 into 1 system they are going to be a market leader.

I hope I gave something useful for you to chew on.. :shifty:

O3RodeKing,

I just purchased the hooker true dual tuned headers but have not yet installed them. I am impressed with the fit and finish and am anxious to hear them on the bike. I assume the mufflers in this system are the same as the slip ons. I went with the Hookers because of the tunable feature and also on Jim's recommendation for my set up.

Jim,

I don't want to hijack this thread but while we are discussing the Tuned flow, please refresh my memory on which setting produces the 2-1 effect. The PCIII maps on the dynojet website are R=HP and L=T. Is this setting for max T or Max HP?

I am having mine Dyno tuned after the cams but just wondered what your opinion was on the settings.

Maalox,
Generally on a Harley the front cylinder runs leaner than the rear. Hence you would want to cork up or resrtict the front cylinder (by setting it to torque) and allow the fatter cylinder (the rear one) to breath as easy as possible (by setting it to HP). This is not a HP or Torque combination, it's a combination of both. Setting one to torque and one to Hp is going to give you the best of both worlds, and aid in averaging out the cylinder A/F mixture between the two. This also give you a close to 2 into 1 combination out of a true dual setup. I would however, while it's on the Dyno play with the settings, and see what numbers it makes with both on HP and both on Torque and each on the different setting. I'm sure others here would like to know the results as well.

Glad you like the pipes, wait til you hear them! :scared:

[Maalox]

Thanks Jim,

Also with the PCIII-usb you can change the A/F mixture to each cylinder which adds another degree of freedom in the equation. :dizzy: If I'm not careful, I could blow my complete mod budget $$$ on dyno time :spank:

So are the maps shown on the PCIII website (R=HP L=T) set up for HP?

If you just want Hp run them both on HP. :shifty:

I recently saw dyno tests with Hooker Slip-ons. One was with both on torque and the other with both on HP. The results showed changes of about .8 HP and about .8 ft/lbs of torque (may have been even less) If you have them installed, it's probably worth setting them up "right". But I don't know if I would choose these pipes simply because of their tunability. I'll try to find the link again and post it. Just my .02

[Maalox]

Interesting, I would expect the tuning of these pipes to approximate the changing of baffles on other pipes. I wouldn't expect a huge difference, but I would expect more than 0.8 HP or 0.8 Ft-lb of torque. I had hoped the tuning capabilities would approximate a 2-1 but yet keep the true dual look.

[Dyna Jim]

Well maloox, guess what your going to dyno yours so that should end any speculation. Keep in mind when you change the baffle settings, idealy you should adjust the map or change it. I'd say you need a good day on the dyno to get everything just right. I have 44 pulls on my bike on the dyno, and you'd be supprised how baffle changes can affect fuel and timing. Before you get dishearted, try them out... :spank:

[Maalox]

It takes a little more than an inquisitive post to dishearten Maalox. :wave:

I'm very satisfied with the selection of the Hooker true dual tuned flow headers and expect some sweet sound, good looks and primo performance. In addition, I have complete confidence that my man Jeremy will :whip: every HP and ft-lb out of my combination.

Hopefully the cams will arrive tomorrow. If I have to wait much longer I'll have to order more parts. :ignore:

OK, so I emailed Dynojet to find out why they had the left on TQ and the Right on HP when they maped the powercommander.

Here is a portion of the response.

"The way we determined which side would be set to what is not as scientific as you think. We wanted an average of the exhaust system so we set the right side to HP (so we could get the air/fuel probe in the exhaust) and the left to TRQ."

You gotta love it :nut:

[Allenz22]

I'm interested in your statement that on Hooker true duel exhaust system one side can be run on TQ and the other on HP to simulate the 2 -1. I just purchased hooker true duels for my electroglide. I purchased the 96+ because I am running an S&S 124". I am under the understanding the I should run the rear cylinder on HP and the front cylinder on TQ. I tried several combinations and this seem to work well. Can you give me your opinion. Also new to bike chat and I hope you get this message.

Thanks
