had my ninja downpipe and backbox fitted today.......

WOW! its made a BIG difference, so much more responsive.
4000 revs plus justs seems like lightning!
and sounds fantastic even pops at rev limit

question is should i now get a remap?, dont wanna push the engine to much but its one of them things i just have to do from time to time.

thoughts on a remap vs engine life?

The remap will get the most out of your downpipe

seems to be ok up to now, with regular services etc. although is a bit knocky (or more tappy) when cold, but i have remote start so 9/10 times the car is warmed up before its driven.
and once it is warm theres no tapping

Is that the ninja sports cat d/p ??

if so,worth fitting ?

yeah fast flow cat, i would recommend

you can hear the flow is so much betters and the increase in performance is very much noticeable.

according the the manufacturers the difference between fast flow pipe and decat pipe is minimal

sounds like the bottom end is on its way out already mate from what you just said about cold tapping. Sorry if i'm wrong

cool.
ive been told from a good source a z4 ECU can cope with a decat pipe fitted if everything else is standard,ie airbox injectors etc so fitting the sports cat and a backbox fitted to an otherwise standard engine should be fine,if you use optimax fuel

id say more like piston slap NOT big ends

what he said, if bottom end was going it would have gone already, if you no what i mean.
