As for the exhaust, before you spend $$ on an aftermarket muffler, try the muffler delete mod with exhaust tips. You will be surprised at the result and so little money.
Sounds tempting - I'm not all that comfortable with my ability to carve up the exhaust system though. If I were to bite the bullet and go for an aftermarket system, is there one that is generally known as superior?
