Pursuit standard exhaust
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 FPV section and ute section trying to get answers.
There is no substitute for cubic inches but my pursuit sure closes the gap
*UPDATE * Pursuit has just run 11.763 and 116.18 mph making it Australias Quickest and fastest unopened boss as well as Australias Quickest and fastest naturally aspirated Boss
