Hi mates!!


I have just finish installation of New Stainless Steel Mongoose Exhaust 2.5" Bore & 3.5" tailpipe on my Escort Rs turbo S2.

Now I notice some kind of metallic noise (like CLIN-CLIN-CLIN) on idle when the car is cold.

This noise disappear 90% when the car is hot after a fast run.

Seems like gases hit across the internal walls of exhaust system and generate the noise.

I think exhaust it is well fitted, with the clamps, joints sealed without leakage and new Powerflex Bushes, so I think that there are no vibrations that could generate the metallic noise.

Is this normal? Will dissapear after long time?

Sorry for my english.

Thanks
