N1 is a great exhaust. I just installed one on my friends SH and at WOT, the baby screams! The performance is good and if you ever decide to turbo your ride, it will even help scavange more power for you. Great all around exhaust. But yes it is loud. I think you best spending your money on a tried and true exhaust setup, rather then some custom jobby from Jimmies Muffler Shack.

The Greddy EVO exhaust is great too... Especially if you live in California. The cops don't bug as much.
