Because it's out of his budget?
Have you checked out the ISR Single exit? Awesome sound for the a great price £300ish I think.
Scorpion is just too quiet.
Many people are satisfied with their Invidia exhaust.
Cobra is another contender in your budget - Although the ISR single exit sounds very similar for a fraction of the cost.
Thanks for the advice guys. I think I am swaying towards the Cobra Resonated with rolled tips, should do the job I may have to replace the cats as well soon as I spotted one of them had a hole.
Is the hole not just in the heat shield though ? If so no worries there until they start rattling and then you could just rip the heat shield off as many have done. Or like me found it the perfect excuse to get some Berk hfc's.
