It keep the gases flowing by keeping the heat in.
Plus it also quieten down the downpipe as you get a little tinny noise.

And the upshot of doing it - as far as tangible results are concerned - is that the faster gas speed is supposed to gain you a bit of torque/quicker turbo spool-up times i.e. anything up to 150-200rpm sooner. So car will accelerate a tad quicker.

You're always better off WITH it done, than without.

Make sure you get good quality heat wrap tho or your be doing it again next year at your cost If your doing headers.uppipe and down pipe then you be looking at about £100's worth of good quality stuff.If your unsure PM Harvey he will give you all the advice you will need.

As above, get proper stuff. I believe the DEI product is a no-brainer on that score...

There're probably some other good brands, but are they likely to be that much cheaper per roll? Doubt it.

Should also help keep the Sports Cat hot enough for optimal operation and MOT passes
