It'll sound like pure crap.

 

Actually when I got mine on I had to drive it a ways down the road to get a welding job done and let me tell you man it sounds like a F**king monster! It didnt sound that good at a cruise speed but the down shifting and speeding up sounded just like an all out dragster! It is WAY to loud, even if your state didnt have a decibal limit you would still get pulled over! Trust me, it was LOUD!

 

sweet \m/ a dragster lol
