on my last bike i just dreamed what i wanted then i built it. Fortunatly my dad has every thing you need to build whatever you want. I had a thunderbird storm and i built magna flow exhuast tip slide ons. It was loud. Sounded bad ass but it hurt my ears on the longer trips. So then i built custom baffles and it toned her down a tad but was still loud ennough to save lives. Probably sounded better with the baffles. Honesty she sounded amazing..... anyhow what im getting at is maybe you can dream what you want then go to your local metal shop and have them build it for you. As far as power goes your taking a gamble but id you apply the science it should work out and hey! You can get those heat shields added to the equation. I think what im going to do is a custom ss polished header with some nice tips. But we will see....
