nah the exhaust isnt blocked, i got a new one put on at the same time.The temp gauge works fine now as it was fixed the next day, but i know 4 sure that the engine is runnin way hotter than before because the gauge only stopped working several days before this all happened. Could it be the extractors making the engine hotter by any chance??????. They done a bloody poor job on fitting the extractors 2. I took it back 2 them and got the head shaved down but its still bloody hot so me and ma dad are goin back 2morrow 2 pay them just a little visit!!!!!! Is there like a law if a company stuffs something of yours then legally they have to fix it???????. How do i talk 2 about this
