New to HQ but have been checking out the info from this site for about a year now. I am thankful for the info and time you all put into this site as it has helped me out with things I have wanted to learn. I know everyone has their own opinions about which pipes they like and have seen many posts in regards to one set of pipes over another. However, I am wanting to know what you would run and why, if you had a stock engine but were willing to do other mods such as reeds, advance timing, air filter, and such without modding the engine itself. The mechanic at the local yamaha dealership tells me to run FMF Fatties and Core 2's, but my brother-in-law has them on his banshee and I am not all that impressed with the sound or the performance. He is definitely faster than I am right now but not nearly as fast as I would have thought and that is after the mechanic at the dealership tuned it all in for him. Any help would be greatly appreciated. Thanks.
