Oh yea...personally, i like tips. I like the car to be loud "outside" the car, not inside the car. With my setup, the car is still pretty loud inside but you can actually talk to someone without having to scream, and it still drowns out most of the cars i race.
The perfect setup would be to have some electric cutouts right after your mufflers and still have tailpipes run after those, so that you can just flip a switch and go from dumps to tail pipes. Then if you wanna get crazy and spend more cash, put another set right after the headers so you can run open headers. It's just a bit pricey since the cutouts are a couple hundred bucks a set.
