I just had these tips installed on my NSX. The old ones looked burnt and out of shape. Cheap mod at 150 total. I think it makes the car look newer and more aggressive. The guy at El Camino Mufflers in Santa Clara installed the tips for 50 bucks. I've been pulled over many times in previous cars with loud exhaust therefore I opted not to get a new exhaust system. Also, since it's a daily driver I prefer some peace and quiet. I hope this helps someone out there!
