^^^WHS^^^

I do this too, especially on cars with mild steel exhausts, it does seem to help them last longer, top tip that.

The number of cars I see that are spewing water/acid out the tailpipe driving down the road after cold starts amazes me.

Spot-on. I knew about that trick, yet forgot to follow my own wisdom. The acid-water has to go somewhere. I'll get the drill out. The only thing I'd add is do two holes. One can clog

Just wondering,my 99T5 is still on its original exhaust..How long should they last before needing renewal.
Has just ticked over 150k but still very quiet and smooth.
How many miles have other members managed. Regards.

Yours is relatively new ! A long time before you will need an exhaust , they are stainless steel ..should last the life of the car ... Many 1990's volvos still going around with their original Exhausts ..
