This should be a sticky because it's a grand worth of damage for the sake of an exhaust.
My car ran perfectly before I fitted the exhaust.

If
this means that the car was running above safe boost and was consequently detonating,
and
the driver kept driving it like this, then yes- you'd kill the engine pretty quick.
But if this was the case you'd expect the driver to notice the high boost levels and take their foot of the throttle and investigate the issue.

.either way the driver should have spotted the symptoms and stopped driving it

The information of a problem was clear, not sorting it would damage the engine next, and it did.
There are way too many people with cars changing things without the knowledge to understand what they are doing, not just MR2s but it keeps us all in work.

Those NurSpec exhausts are bloody lethal.
Fitted one to Craig's engine last winter, and blow me, it cracked his block a few months later.
Changed engine, fitted a Mongoose, and no problems since.

This all happened over a period of about 1month-6weeks.

I have always had bad luck with cars.
12psi is all it will be running from here on in.
Cba with breaking cars all the time.
My trusty williams powered 16v has been a gem since the mr2 has been broken though
