May 13, 2011I bought a set of used thunderheader slipons from a friend for my 05 Road King. Had been running Screamin Eagles.Wow they sound nasty. Just from seat of the pants feel I think I lost some low end torque, but it seems to come on really strong about 3,000rpm.The motor is a typical big bore 203 cam setup. I had it flashed at the time. Do you guys think it needs flashed again? I read on another site about bending the tabs, but I don`t see any tabs, am I missing something?
May 13, 2011Flashed? If you mean one of Harley MoCo`s canned tunes then hell it needs a real dyno tune.That ought to wake it up.
I`d Rather Be Depraved Than Deprieved!
May 13, 2011Hey Freewilly,
You going to Sturgi this year?
If so maybe we can hook up this time, I will be out there during the week of the 8th - 14th. I am still looking for a place to stay that does not cost too much. I will see how that goes,, I have put out an add on craigslist.
Anyway, do you like your pipe?
Are you going to be able to put up with all of the additional noise?
I really do not think a reflash would be necessary , you just went from one open muffler to another, don`t really think it would make alot of difference in the mixture. But I ain`t sure, maybe Tat or Trip will comment on this post.
Freedom is not just another word, it is riding my harley down the road with the wind in my face.
May 15, 2011Sounds like you should be OK. Whatcha doin` with the SE mufflers Willy?
Freedom isn`t free. If you can read this, thank a Teacher. If it`s in ENGLISH, Thank a VET! The right to keep and bear arms shall not be infringed.....
May 16, 2011VT yes I`ll be at Sturgis this year not sure what days yet as Linda is talking about going again which really complicates things.
EOD I put the SE pipes on an 06 Ultra I bought, it had a stage 1 air cleaner and a tuner but stock pipes. I think he kept the pipes when the bike got repoed.
As far as the performance with the Thunderheaders I did a scientific test yesterday. When shifting into second my adult beverage popped out of my beverage holder, it`s never done that before so I think the performance is improved.
Love the sound Linda says no sneaking home late at night anymore.
