Exhaust seems a bit 'raspy' when cold

deanobeano · 19-07-2013, 11:41 AM

Standard exhaust - seems to be noisier of late. Only happens when cold. When warm it turns into its former self...

I would describe the noise as a bit more rasp (this is at low revs, just pulling away from home) and I suppose a bit of rattle.

Will be booking a trip to Elms post Donnington so will get Gareth to look at it, but if you have any suggestions.

Thanks

They all do it. Probably a bit of over fuelling when cold and I think I read somewhere that there is ERG type of system used when the engine is cold?? The primate will soon chip in.

Ok for some reason I always thought it was thinner exhaust! But they all do it I think.

You should hear what it sounds like with the Supersprint "Race" back-box - it sounds REALLY basey from cold - so much so that it rattles our house windows (so my other half says) and hurts my ears inside the car until it has warmed up

I have the SS racebox aswell and the sound when its dead cold is amazing! it rattles, splurges and pops especially in first and second gear when letting off the throttle.
