Thankyou mate
Yeah im looking at a 4-2-1 de-cat atm, just struggling to find them anywhere apart from ebay funny you mention powerflex bushes, they are on the list of things to do cause the rear axle bushes are shot to bits atm.
As for the filter im running a cone atm that next week will have 2 50mm air ducts running from the bumper to it, but would a panel be better still? Mmmmm think cams are sadly abit above the budget
