Hi and thanks for the reply,
when the bloke fitted the exhaust, he didnt take of the cat pipe, he only moved it a few centimetres. so dont think he disturb that.
i have had the exhaust on for a bout a week, and driven from london 2 portsmouth about 4 times, clocked up about 1000 miles and still no difference. still sluggish and the noise is only slightly rumbly at about 5-6000 revs?
also do you know if a magnex exhaust should have a magnex stamp engraved on the metl anywhere?
thanks
