I just got true duals on my 98 ss camaro and when I started driving it, it vibrates a lot when I accelerate. Any reason why and what can help to fix the vibration?
The brackets are not either tightened down or there are no shock absorber gaskets on the brackets where it connects to the frame. There are holes in the cross members for the exhaust pipes to go through, and if aligned properly, will not touch the cross members either.
