Secondary cats removal

[GAZ-MAN]

Well now my mate dislikes me as I gave him the challenge to fit some decatted downpipes all cats now removed and bigger intercoolers and a full service so should be getting the car back tomorrow and back up to ecotune for another map

Can anyone answer the question of, does fitting bypass pipes to remove the secondary cats put an engine light on? I've bought the same Supersprint bypass pipes and wondering whether to fit them or not. Will be a long time before the remap happens

no engine light lee.

Cheers! Game on

How much difference did the secondary decat make to the noise? Does it rev easier?

My engine management light is on but I'm thinking it's cause all the cats are off now?

[GAZ-MAN]

Spoke to Stan at ecotune said the light is on because of catalyst efficiency fault code cause I changed the downpipes said once I get stage 2 on it he can sort that but the car is absolutely flying as it is just now

What coolers and how did he remove the pre cats?

Where he located i'd be interested in a similar service!

I bought the downpipes mate straight pipes from the turbo 3.5" and he also supplied the intercoolers I got them off him at a excellent price as it was a previous customer who ordered them in paid a big deposit then he said he didn't want them, It's ecotune in Glasgow mate
