Hey dude, best way to take off the labels is first getting it in the sun and letting it heat up, then taking it off reallly slooowlly with your finger nails...you just have to take of big chunks of it. Then buy goo gone or goof off from the store to get rid of the sticky stuff by spraying a lot of it on and using your fingernail to remove the sticky stuff. It takes some time but its worth it. If you want to take off the bumper badges I used some floss and slowly worked it back and forward until the label came off. And again use goof off or goo gone to get rid of the sticky stuff. We tried a credit card but it may leave scratches. So i would stick to using your fingers.
Yes I have a Vibrant RH no cat and Full Race exhaust. I absolutely love the way it sounds. Not loud at all when cruising or at idle, just a deep rumble. But, when I hit vtec it sounds amazing!! In my opinion it is perfect. I did have trouble with the exhaust hitting when I shifted or the engine moved, due to needing stiffer motor mounts. I switched the stock exhaust hangers for stiffer ones made of polyurethane and the problem was solved. IF anything definitely get the full race exhaust. I picked vibrant header because it is a quality made product as well.
I like it. I got the Invidia q300 and it isn't that much louder than stock just a little deeper. and na I didn't need it. I think that is only needed with the header so the check engine light don't come on.
