Thanks for the reply.
I am considering price for sure in the decision and if I figure it is just too much will not do it. I do however think that whether it is worthwhile or not is pretty subjective. As, in my experience a good exhaust adds exponentially to a bikes performance. I would list it at 1 - suspension 2 - tires 3 - exhaust... then maybe a good seat. And, points 1, 2 and 3 are the cheapest made most poorly functioning factory items on most bikes. I don't want the sound that was the purpose of the post. And, the gs exhaust with the catalytic right under the tranny adds a huge heat sink to the bike that I can do without.
Thanks for the point of view.
