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!
I've said many times that my exhaust (Dutra Duals through turbo muffs and true dual exhaust) sounds like a vintage WWII fighter plane when I'm on the highway. Like a V-8? No. Way better. :)
