The Milltek makes a good upgrade if you want a small sound step from the OEM system, it's also really well made, all the ones we have supplied have fitted perfectly...
The Cobra Y Pipe we do is a great replacement for the OEM one, priced at £199 delivered...
Drop us a call or email if you need any further information...
Ken, we have a local member who has this fitted by us, Berks HFC and stock exhaust, the sound was excellent, we're still in contact with the owner if you wanted us to arrange a meeting with him...
