Thats funny, my SS has the full Kooks system and it drones like crazy in 6th gear from 1800-2200 rpm.

Whether a system is a cat back or axle back does not determine if or how much it will drone.

Exactly! I agree 100% with you. If you want a loud exhaust, it's going to drone. If you get a more mild one, it won't be as bad. I had JBA's Long Tubes with their Hi-Flows and 3" catback and it drone like a SOB. The J-pipes helped out quite a bit but it was still there, and it quieted the system down a little too much for my liking.

Now I have the Outlaws and they're perfect. They do have a slight drone, but its more of an exhaust noise than the head pounding reverberation that the JBAs made.

If you want loud + no drone, straight pipes all the way!

With all that said, I never had ANY drone problems with just a catback system. It was once I added the headers and hi-flow cats did the drone issue come up.

Lucky. I had drone really bad and J pipes killed it. Only a little, nice exhaust note on the freeway now and love it. It could also have been the cars natural frequency or the mufflers build quality might not have been just right
