I really liked my Fullsac components, loved the sound of the SD cores. Unfortunately the Fullsac setup would not work with my new combinations of parts thus going with a Dragos. The fit of the pipe is a little tight around the floor boards and cam chest but does fit. As for the pic of the O2 sensors to my untrained eye it looks like a tune issue however the O2 placement could be the culprit as mentioned by the far more experienced.

I've never been a 2-1-2 guy. Always run a 2-1. I know that Steve from fullsac knows his stuff, just not the right direction for me. I'm most likely going to take the bike to Frank for some more work this spring so I am sure the issue will be resolved he builds some pretty potent stuff.

Not interested but Steve is a great guy.

It's not always about you.
If you will look back to my post, I copied Ohiobellboy's post and responded to him.

Some of the major manufactures of pipes you mentioned, are not concerned about the 02 sensors working or reading accurately. Sound is what sells the pipes, then the looks of the pipe come in a close second. Whether it makes hp or not, or its tunable unfortunately has very little to do with the manufacturing.

Yup, and they charge three times what the pipes are worth because they know Harley folks will spend way more than something is truly worth as long as it's loud and looks "cool". 

The truly sad part is that these pipe benders don't even have to do the science and engineering to get it right.  The information is available from the experts like Bosch for free.

Had D&D Fat Cats on my '07 for several years.  Performance was fine as far as I could tell but after learning about O2 placement and reading installation details on Bosch's website it was obvious to me that on my headers the bungs were not proper - they were way too long and did not allow the sensor tip to be sufficiently far enough into the exhaust stream.  As far as actual location on the header pipe I think they were OK.

Wound up replacing them primarily due to them being too loud even though they had the 'quiet baffle.'  Running a Khrome Werks cross under style header now with Fullsac 1.75" baffles in my stock cans.  Runs great, sounds good and is way, way cooler than when I had the D&Ds.

Exactly, it's not always about you. So how about you stop following me around and slamming all of my posts? It's really getting annoying...

Chip thanks for the caring PM. You are a very nice fellow I look forward to riding with you.


" Following you around. There you go again flattering yourself thinking your post are worth my time.
My response was to Ohiobellboy not you but you had to jump in. Maybe your following me around. Have fun with that!
Slamming your post, if I wanted to I could you make it easy, but after a review of the content your post aren't worth the effort. But there you go flattering yourself again.
As far as being annoying, go look in the mirror.
You will see, "there" it can be all about you.

Chip"

Again, sure is great having such a wonderful person to engage on the forums. You truly are the toughest guy on the internet. Thanks for turning a thread into a personal attack, as usual.

Same issues with my d&d fat cats, O2 placement and the awful amount of heat coming off the rear pipe.

The heat was unbearable at times.

You'll love the Drago pipe. I sell a lot of them and use them on my own bikes. Frank is a great guy and he stands behind his products. On top of that, the ceramic coating on the Dragula really helps with comfort in regards to the heat coming off the radius bend of the rear cylinder.

I don't condone using canned maps but if you're going to get one, I would call Frank for it. Jamie wont have a map for that pipe and the exhaust is a huge player regarding tune/map.
