Gymkata, objectively though was there a big diff? Is power jump worth the extra db in sound? How I wish Akarapovic will make exhausts for our baby.So...I had the pleasure of riding around in Jaslapp's car today. WOW!!! That thing is wicked. It is definitely meaner than stock, but the sound deadening of the car makes it quite bearable with the windows up (Of course everybody has a different tolerance to noise)...
