If your going to buy pipes you might want to try these, there cheap, loud, and can get you going untill you decide on something else Emgo pipes
I haved the long TOR but ordered a 2 of the 12" short pipes to try a new sound and if I don't like it I'm only out $40. Just a thought. I like to hang on to my stock pipes just incase I ever need to pass a sound ticket

Ahh beer its not just for breakfast anymore
