I have a pursuit Mk2 ute and I'm wanting to know how restrictive is the standard exhaust.

Has anyone here only changed their exhaust from cats back and picked up much power (not taking into account exhaust noise)?

Why I'm asking is, I'm thinking about putting Di Fillipo extractors and hi flow cats on, but thinking about leaving the standard exhaust to keep it quite (just to keep everyone thinking it's stock), But I dont want to keep it if it is going to be restrictive. I understand it may not flow as good as a 3" single sports system, but if it's only , say 1-2 kw's in it I may keep it.

DiFillopo advertise an 18 rwkw gain using their extractors, hi flows and 3" single, but it comes out at 94 db, and thats their base system, then they have a big one that gains 23-25 rwkw but is rather noisey.


I possibly will also be using ss induction cold air intake, BMC filter, Helix spacer and possibly undedrives and later on boss edit.

I will also post this in the exhaust section and FPV section trying to get answers.

I haven't seen if you got replies elsewhere but I have done just what you said. I fitted Herrod headers and cats and left the standard exhaust on from there.

The Pursuit exhaust is identical to the XR8 exhaust and is known to be quite restrictive. I'll eventually get my own custom system made because I don't like the sound of a single exhaust.
