Ok upto now, found a company in shanklin on the isle of wight who will do a cat back system with single backbox for £423

sent an email via the powerflow website to 2 garages one bridport and can't remember other but neither have responded.
Spoke to JMl (or is it midlands exhausts now?) in walsall who can do me a quad system cat back for £350 and if i want a sports cat added is another £150 so £500 all in.
Think i will save the money up and make the trip up there, just got to get wifey to understand why i want to spend (our) money on an exhaust thats 4-5 hours traveling. Maybe take her with me and pretend its a holiday
will let you know what happens.
