Too good is what I say... As an old street drag racer, what we'd do is uncork our headers. Meaning, we had a mechanism to uncouple the restrictive exhaust and let it flow. This also can be accomplished similar to the GT-3 muffler with baffles. I asked Mr Bizi to create one, while I attempt to create my own. This would be for long trips etc. easy on and off, Quiet-Riot, or mechanical valve.
