Go for it.
I installed mine in about an hour and a half.
The newer models are a little quieter and seem to fit better than the earlier models.
Just use one set of exhaust gaskets if you do the install according to the way they are written up on the board.
I used two and mine have a slight leak at the block. Gotta take 'em back off someday, remove one set of gaskets and reseal.
You'll like the sound or hate it depending on your taste, but they have a nice strong tone over the stock versions. :wink:
