Hi had decat fitted yesterday,when driving in 1st and second,the dash and front vibrates a lot,especially uphill.Does this mean new engine mounts or get the engine moved forward a bit.Also has polybushed dog mount,but vibration is much worse since decat

Any help thanks

Ah ok.

well there is a Kangoo engine mount that fits the 172, and is stiffer. Thats the one i would go for.

Easy to do yourself. Jack under engine and undo all the bolts.

Hows your car sound with the decat? I have one on the way for mine and im hoping for not much extra drone on motorway but nice when pushing it
