I just finished my true dual install, dumped before the rear axle. I used moroso spiral flow mufflers. I got everything tucked real well, but I have a terrible vibration at idle and around 2500 rpm. I mounted them just like this pic, http://www.lt1engine.com/media/album_page.php?pic_id=13 I used the same style hangers and mounted them into the seat belt holes, but mine has sumps and dumps right in front of the rea axle. Does anyone have any idea about what would be a better hanger location? Also, I removed the hangers and started it and the vibration was gone. Where do most guys hang their true duals from?

Any exhaust that is dumped under the car, be it a cut-out or a dual dump w/ mufflers will increase sound levels inside cabin aswell as vibrations.

I will try that out.

I know they vibrate, I had dumps on my last car. But these vibrations are ridiculous. I mean it sounds like the car is vibrating apart.

ive always had a vibration with my true duals, but it turns out its actually the headers, and solid motor mounts will fix it.
