While were on the subject of catless DPs..

please could someone advise if -

It would be better to get them installed pre remap

Are the DPs something you should notify your insurers of, and if so what kinda boost to the annual premium am I looking at ( ball park figure would be nice )

Am i correct in saying the DPs would only better the engine, i.e not cause extra stress / problems to the engine and exhaust.

Do the catless DPs change the exhaust note in anyway ?

Ive no mads what so ever at present, but really want to start increasing performance safely.

all advise is appreciated
