That's a completely different car with a completely different motor. Your statement is not beneficial to any side of the argument here. STis have boxer engines which are known to produce low, deep, and rumbling sounds where as a regular inline 4 cylinder is much louder. The turbo helps resonate the sound which is why turbocharged cars have a different sound than N/A cars. However, the evo and STi shouldn't compare in exhaust loudness because of the two very distinct and different engines.
