Anyone out there running ‘stage 3 cams?’ Usually way to aggressive for a street driven car but I’m thinking 'tuned well' its not a lot different sound wise, than some of these more exotic muscle cars.

 

What engine do you have ? Big cams in a stock internals engine will perform poorly in the low and mid range and make similar peak power as a Stage 1 or Stage 2 camshaft... it will sound "lopey" but that is it... even if it is "Fully Tuned" as you have suggested.

 

I’m currently in the process of rebuilding my H22A7. It has (though yet to be installed) after-market uprated internal components, for either increased strength or lightening.
I'm just hoping it isn't going to be to obnoxious. The Torneo-R was running a 2.5" pipe (without cat) through x2 twin loop Mugen mufflers.
