And I'd LOVE for my car to sound like it actually had balls, but alas, I have an econobox... A 94 GS-R, but an econobox nonetheless...

Personally, I have a GReddy Evo exhaust. Super low idle note, and probably the quietist straight-through single pass muffler on the market. I get compliments on it's note from the bigblock baddies, and to me, that's the biggest reinforcement one can get IMO...

And if you had a SVT Cobra (not mustang, BTW), then I'd be impressed. That's a quite a decent car... but a GS-R? Meh... I have one, and while it's fun, it's not an impressive car...
