Are exhaust heat-shields necessary?

[Space Cadet]

As above, are these just for driver comfort (shielding the heat from entering in the car) or do they protect the bodywork or any gubbins? They’re a pain when working on the car (track car) and was just wondering about removing them completely. Thanks Mark

We have non on the race car at all.

protects a few things on a road car that matter, like handbrake cables. Also the cat in the standard position is right under the gear linkage, the heat from this can effect the bushes and plasticise the grease. Track car with a decat......not so much

Thanks guys, I was just about to ask whether the gear linkage/ball-joint thing is ok with the extra heat and exposure to the elements, but I don't have a cat.

Do you have a heat shield between the manifold and the bulk head still?

Yes Mark, just to protect the brake pipes.

What about the heatshield covering the fuel tank?

 

[Tony Hunter]

What about it.

Don't forget, we don't sit in traffic for hours. So no we haven't got one.

Didn't James have problems with heat affecting his gear change or was it more to do with it being relocated ?

 

[Tony Hunter]

Relocation I think, our's has been sound.
