Hey, I had a true dual exhaust put on a little bit earlier this year with an H-pipe. I'm getting a real heavy interior buzzing around 2,000 - 2,300 RPM's. I also get an interior vibration at around 3,000 RPM's. That's the only mod I have right now I don't have headers or intake so please help! Thanks!

It appears to be the dreaded drone. You can have some 3 inch resonators installed in your exhaust system that are staggered. They should help to eliminate the drone.

get under the car with a rubber mallet tap the cross bar at the tranny. if you have a vibration you can install 2 3" hose clamps around the rubber mounts for the cats . its a TSB but since you have duals now they may not do it. i did it about 2 weeks ago and my noise is all gone.


here is the tsb it explanes how to do it. took me about 20 min to do!
