IMO, if you're already doing the work to remove the exup, might as well get rid of the stock collector as well. Look at the 2nd pic in my original post, any true 3-1 collector is going to out flow that. It helps too if you have fabrication skillz, it cuts down on the cost you have to pay others to cut/fit/weld. But even if you have to pay someone to do it, I know of others who have had this done for around $100 bucks plus parts, which really isn't too bad.

Do you think this job could be done with an arc welder?

Once the exup is removed wont it set off the warning light or no?

Download TunECU and get the correct cable and you can disable it in the tune you use and clear any error codes you have.

I am doing a custom side exhaust for my street fighter - the pipe will be fairly short so wouldn't the bad flow help cause a little back pressure that it'll be lacking otherwise?

The smallest dia pipe in the system will determine back pressure if it is a continuous system. If you have a chamber depends on whether the outlet is in line or off to the side.

I can't see bad flow helping anything. Even when you buy a full shorty exhaust like a Zard for example, they all use true merge collectors.

Just got mine done today, was about a 5 hour job with the help of my buddy Kevin. I had the bike dynoed on Thursday with just the Akra slip and will be going back this next Thursday to see if anything was gained.
