/6 single or dual exhaust?

Not trying to make anyone mad, but.....unless the exhaust manifold is split, inline 6's sound like a mail truck. I hope your header setup is! When they ARE split, I think they sound better than a V-8......such a tough sound......like music!

One thing with headers though and that is you'll have to fab up some sort of carb heat source to prevent carb/intake icing in the morning, since you won't have a hot exhaust manifold bolted to the intake any more.
