Ok so I have a 99 R/T with dual flows 40 series. It sounds pretty good but I'm looking to make it sound a little meaner. For instance, I was sitting at a red light and another R/T when passed me in the turn lane and he truck sounded really loud (but not annoying) at almost no throttle. I was thinking maybe if I got a high-flow cat it would sound better. Would the cat do anything to help, if so what kind should I get?
Thanks,
Dave
