Hi

Ive a 2008 impreza (1.5r on a 08 plate)

rear heatshield under the rear silencer is vibrating like crazy, had a wee look and the fixings and washers are still in place but the thin metal heat shield has broken free, it is closest to the N/S and is approximately 2ft x 1ft

Options seem to be to either try to get the rusted fixings off and replace with 50mm washers or just remove it completely.

what would be the risk of just removing the heatshield?

 

I have done both before - Ran without heat shield, ironically a freer flowing exhaust does not get as hot. but repair washers mean you can address with exhaust in place
