As best I can remember, the TOR pipes are around $450 - 550. The jets about $6 each, and about 1 - 1.5 hours labour.
Part of the confusion is because they made 3 different versions of these pipes, progressively louder. If possible, try to get a live listen before you buy. Some people love the sound of these pipes, others hate them. As compared to the other aftermarket pipes, the TOR's are still the quietest.
After you get some better breathing pipes, it would be a good thing to pop whatever rubber bits are in your airbox out. This is easy to do, and it can give you up to 5 more HP with your new pipes. With the original pipes, about all you gain is a different sound in the intake. The engine has to breath better at both ends to run its best.
