What mufflers?
Well, the proof is going to be in the pudding. I have a set of Super Turbo's sitting in my garage waiting to go on.
Even with the exhaust going all the way to the back the car was very loud when I got on it. The most annoying time was driving down the highway. The drone was unbearable for the wife and got to me a little as well. Plus it is nice to be able to hear the blower whine to. LOL
We will see if I made the right choice this spring.
