So last week I received my Miltek secondary decats. Wanted to remove any potential issues at MOT from the non experienced Audi inspectors so filed down the welds on the tags that say ‘not for road use’ until the tags came off and filed each weld until smooth. In a few thousand miles when Pipe is discoloured it will be invisible. The sound combined with my sports exhaust is amazing. Plus the brand new secondary decat package was on eBay for £100! Boom!!
