Need help
 

I just installed a quad carlsson exhaust system, it looks amazing.......BUT i installed it on the stock 2000 ml rear bumper, so while the car is on drive and not moving, it produces the most annoying ratling sound ever mad: because of the vibration of the car, ANY IDEAS????



also, i recently noticed there is a sound coming from somehwere behind the stearing wheel, it is more like a metal resonance, anyone ever got that????


Your input is greatly appreciated!!

Thanks

I had a similar problem with my previous car and it turned out to be the heatshield on the Cat Converter
