I beilieve to get it out easily you need to remove the flex pipes, some have forced it out but not pretty. When I removed mine I drilled out the rivets holding the header braket, but be sure replace rivets with quality ones. Also there are 2 alen bolts holding the header to the bracket, losses those off a little no need to remove completely.
Hope that helps

Ok thanks I ended up removing the flex pipes and got the new one on is there a easy way to check for any exhaust leaks before putting everything back together?

I hooked the tank up and started it got a lot of smoke inside the manifold Area is this normal with a new header and copper donuts or do I have a leak somewhere it doesn't seem to smoke until. It's been idling for about a minute

I recently installed copper donuts and had quite a bit of smoke too. I let it run a few times and the smoke has subsided. Maybe it is the copper donuts... or the penetrating oil I used when dismantling it in the first place.

ya thats what I'm thinking i would imagine you should here it if you have a exhaust leak more than anything

do a wet rag test or a tennis ball. start the sled and plug your exhaust if it quits you have no leaks. If it spits and sputters you have a leak.

RDAY, I went through the same thing in January. I changed mine and had a scary smoke show. Button it up and ride it, the smoke will stop. I didn't take the flex pipes off. I drilled the rivets and removed the mounting bracket. Good luck.

Ok i got everything back together and I noticed that there is a small leak where the silencer connects to the header pipe is this a big deal or no?

Fix the leak. It could lead to buying another header.

What would cause it though the gasket from the header to the silencer looked in great shape? And does anyone have a tip for reinstalling the shroud over the exhaust easier what a pita lol
