Do you have to change the exhaust to a larger 4" when this is installed?

no I did not it will not affect exhaust volume enough to worry with hope that helps

No, it will not work. Your stock exhaust size is 2". This one is just a little too big. Unless you have changed your whole system, then it would work.

The exhaust can be configured to the existing exhaust if there is one. It can also be configured without an exhaust. Easy to convert.

Yes it should be a direct fit ! And if not the muffler shop that installs it will have an adapter that should only run a few bucks extra ! This muffler is nice if you don't want a super loud exhaust I took the silencer out and it's not obnoxiously loud by any means it does seem small though

No it does not, its just a filter change, you are not changing any part of the engine, you are just replacing an air passage,+ it comes with a paper in writing that says it doesn't in the instructionsNothing to worry about. Look forward to great sound

I would think that you can buy a large dia duct of the right length to extend the exhaust end of the stock unit. But I don't recall any instructions in the package that addresses that possibility. I only had to penetrate the 4 inch stud wall to the outside of the bathroom.

Yes, I can personally confirm it does fit the stock exhaust on a 2011 4-Runner... looks pretty nice, too!

Yes I did have issues, they said that the exhaust would bolt right up and when I received the system it did not. When I contacted them they told me that I may need an adapter pipe. The system was coming up short at the rear mid pipe, about 3 inches or so. So I had to go and pay someone to fix it locally. I recommend spending a little more money for the right part.

It replaces the one Ina 4" system. I used Tito remove my muffler on my 4" system

Sorry I can't help with this question. I installed this when I was doing my bath remodel and the installers made some mods to my exhaust (my condo is 30 years old), and I wasn't home when they did it.

It fit mine...but I would confirm with a toyota dealer that your exhaust specific to your car did not change.

No. It screws into where any O2 sensor goes into. That being said, you don't unscrew and replace it with one of your O2 sensors. You need to have an extra O2 sensor bung on you Y pipe. My race 3 inch exhaust had bungs for both my O2 sensors and an additional one for this set up already to go. If your exhaust doesn't have that extra O2 bung (threaded hole) then you will have to have a bung welded to you exhaust in order to screw this sensor in. It should be positioned behind ( further down the pipe between the last O2 sensor and your CAT). Hope that helps!

No, just remove the black stock muffler and it should slide onto silver pipe coming from manifold, I hav looked at the new KLR but I don't believe they've changed the engine or frame, mounting points should all be the same

I'm not sure if that's possible. But if you have a 2.5 dual exhaust off of your engine, and you made it become a 2.5 single exhaust, I would imagine that you would take a step backwards in your horsepower. I don't think that would be worth the money of buying a nice muffler.

You shouldn't have to do anything different if you have the stage one download already. I put exhaust on my 07 softail and didn't do the the intake and filter until later because of the money.

I do not have a definite answer for the question. I have worked on cars for many years and have came across 2 1/2'' exhaust a lot more times compared to a 3'' exhaust system. Maybe the company is trying to capitalize on what people purchase more.

Probably not you need to check if the exhaust pipe on your truck is 4 inches in diameter and the overall length of your muffler is 30 inches I believe stock exhaust is 3 inches in diameter and am unsure on length.
