Welcome to the group! There are dozens of threads on this. Some go with TORs, some go aftermarket, some drill holes in baffles, some remove the baffels. The performance improvements are very good. Estimated between 6-10 hp at the rear tire. It is recommended that you rejet, and necessary to remove the AI system or it will pop on decel like crazy. Use the search function on this forum or just look back in technical talk > exhaust under beat out baffels. TONS of info on this. I personally have had D&D's , totally gutted out America stockers, and have a set of JC Whitney turnouts on the way (which will be hollowed out ASAP. I like loud pipes!). If your BA (Bonniville America) is an 07, it will be hard to drill or gut the pipes due to the peashooter design. There are alternatives from cheap to high dollar. Check the classifieds in this site. I sent a "wanted" thread out and got offers for some gutted TOR shorty's and the JCW set that I bought. the guy selling the TORS might still have them and want to sell them here

Go to
http://www.newspeedmaster.com/ and get a jet kit, carb screw kit, "D" tool or thumb screws, and AI removal kit. then, pick some pipes that I like the looks of. For there I'd find that style withthe level of sound db that suits me. Some are loud, some very loud, some are tunable. Either way, the stock one are VERY restrictive and just gotta go!
