Put new exhaust on and I get a rattle

[clio-16-valver]

Just put on a full magnex exhaust system and magnext de cat but now I get a knocking.

Any ideas?

Seems to be coming from near the front.

Anyone?

prob exhaust knocking on subframe due to knackered engine mounts. take it its a 172?

 

[clio-16-valver]

Yeah.

What engine mount do I need?

 

[big_dave_r]

[clio-16-valver]

Get a vibration, more of a knock when i start and turn off car (also braking)
