I don't want to have to run 91 octane fuel. Consider the direction that this world is going in terms of fossil fuels and the availability of good gasoline. Since these cars were new, we've already gone from being able to get 101 leaded at the pump to now getting ethanol-diluted 91. Where are we going to be in 10-15 years? No, I'm not building a motor that requires good fuel for what is going to be primary, every day transportation for me.
As for the exhaust, I don't want my car any louder than it is now, and it's pushing it even as it is, so I'm going to keep my dual 2 1/4".
