Hello,

I was wondering if anyone has fitted a high-flow catted downpipe (Milltek or similar) without having to get a tune or stage 2 tune?

May have to replace the downpipe soon but not sure if I'd be better suited to save the money and get a catless with a tune or if I can avoid having to pay for a tune with a high-flow catted downpipe

Also, currently running JCW Pro exhaust, Dinan CAI, Forge hard pipe, and NM Power Module

Thanks in advance
