So, my thoughts on this leave me with many questions.... I have determined that there are only a couple of aftermarket exhaust systems out there for a 2010 Stratoliner that don't require the removal of the exup valve...otherwise, there are many options....so, is there any harm in having this valve removed? will it effect the performance of the ride? does anyone out there think it may become a warrranty issue? or in the long run, running without the valve - will it cause harm?

ALSO, how difficukt would it be to remove the valve? I would assume all the connecting wiring would haveto go too?

Technically it will probably void your warranty, but you should talk to your dealer before making any changes like that. My dealer doesn't care if the exhaust is changed he would still honor warranty, but some may not. A good dealer that wants to build a relationship with you since you just dropped a sh@tload of money on a new bike will honor the warranty even if you've done a few minor mods like exhaust , air cleaner and processor. As far as the exup is concerned, it is an easy removal. It comes off with the exhaust and you just have to remove 2 cables and it is disconnected. and no it won't cause any harm.

so...if I go with exhaust only, would I Still need the Processor? I always thought that fuel injection can adjust itself for minor changes...now if An aftermarket air cleaner were to go in, I know then a processor would be best.....

I ran my aftermarket exhaust for the first year I had the bike without putting in a processor and air filter and it ran just fine. When I added the processor and filter It wasn't like all of a sudden my bike was a monster, but it just felt smoother and crisper with a snappier exhaust note. So yes the factory brain will keep up with just an exhaust swap , but if you got the cash just get it all. If you don't have the cash just get the exhaust and you can do the processor and filter later when you have the money. It is an easy install. Yes if you change to a high flow filter you should definitely do the processor.

The Ex -Up is for low end torque. If you remove it you will loose some low end torque. Below 2,400 RPM I believe. With a good exhaust you would probably make it up in high end horsepower.

I have seen some reinstall it and some very happy with the new exhaust. All in what you want. I kind of like the low end torque. D&D has a slip on that keeps the valve. I'm still stock. The air intake change will increase noise. Didn't want the increase in intake noise.

I put a roadhouse slip on exhaust on mine with a K&N filter and have been very happy with it. Roadhouse has since gone out of business. I run the stock ecu and the lid for my air box is raised 5/16 of an inch for a little more air flow without all the noise.

ok....so for a new query...what type of processor's are guys using?

I just did a drop in replacement K&N and Roadhouse classic 2 into 1 so all I needed was the cobra Fi2000R. If you plan on doing the big air kit I would recommend the PCV. I don't think the cobra will keep up with the big air kit. I have ridden a bike with the BAK and PCV and its definitely an animal, but I'm happy with my setup. I can autograph an intersection at will, so I've got plenty of power.

My fuel processor is still stock. Many seem to feel if the exhaust is all you change the stock controller can handle it.
