I think Rags original post would eliminate all the backpressure and make the bike run that crap no?

JJ23, In short the answer is yes, but then again no... Degoating has been going on for a long time. It does hurt bottom end performance a little, but with properly tuned carbs combined with an earshave, it helps out the top end.

I think Fargo did a kickazz job on his H pipe fab....bravo, bro !.....

As to backpressure, what few realize, is that if you remove the belly, but add BAFFLED muffs, the backpressure stays the same pretty much....main difference, is its not as balanced. Thats done with either an H pipe (proper way), or drilling a few holes in the left side baffle.....

X2 Fargo. When i finally get around to replacing the belly with a h-pipe, I'm going to put torque cones in mine. The screamin eagle baffles don't provide a whole lot of back pressure.

The first time I pulled the exhaust shield off I was wondering if I can do the same thing!!

I guess it'll be this weekend's project. I'll try the de-goat without doing anything to the stock mufflers to see how it sounds. I don't want it too loud either. $20 for some flex pipe, if I don't like it, it's fairly simple to reverse it.

This forum has been very valuable already!

Attempted this earlier. I got pretty much everything done, but when I was putting the front side of the flex coil to the header pipe, it's really loose. I tighten the U-clamp over it, but it just crush flex-pipe, which creates a crazy leak. What did you guys use to as filler or shim?

I'm going to have to get another flex-pipe to try again tomorrow and maybe some kind of shim or seal of some type since the flex pipe is slightly too big and doesn't crush down well to seal over the header. Maybe cutting some slits into so it doesn't crush in and actually folds in?

I'll try again tomorrow and see.

If the leak isn't really bad maybe try some permatex rtv and the clamp? Also IMO don't use the u clamps the flex pipes come with. Find Harley Davidson exhaust clamps on eBay. There really good and cheap

I'll try it with the stock clamp and shimming it with some flexible steel exhaust hanger material.
