How do u take that off to put a bigger on on does any1 know is it perminent or something

 

I've been told that it is just a press fit. Makes sense because I've seen a lot of Maximas without it. Wack it from the front (of the car) with a rubber hammer.

Most aftermarket tips attach with set screws.

 

The stock chrome exhaust finisher is actually clamped on. If you look into it you will see this. To get it off, take a screwdriver are pry off the clamps from the actual tailpipe. Then knock it off with a rubber hammer (if you use a metal one it will be ruined. Lots of aftermarket ones do screw on, but can also be clamped on (method of choice). The advantage to clamping is that some Honda boy can't fly by, grab it and stick it on their car. If you have an aftermarker exhaust (which given you dont), you can weld it on, seeing that you most likely won't replace it. I would suggest you take your car to a gas station (dont need to go to a special aftermaker auto place) and tell them you want it clamped on there. Just trying to help.

 

I see that you relocated your battery to the trunk. Did you notice a significant improvement in handling?

 

It has really helped reduce understeer. I have actually gotten the rear to come around a couple of times on the autocross track.
