Has anyone done any exhaust modification? Maybe installing a remus or other aftermarket exhaust?
A family member has a 4.8is from 2005, and that exhaust system is about the best sounding/compromise at crushing speed I've encountered. Loud when you want loud, quiet when your cruising.
I feel like my 08 4.8 is very quiet all the time. Would love to get a little extra growl when accelerating.
Did a few forum searches, didn't run into much. Anyone running anything?
