Hi all..

I have a Magnex Twindump downpipe and am just wondering if anyone would know if it’s a 3in pipe or not…..If not could someone please advise me what to get to replace it.

On my last remap the chap said he could only get 306bhp out of her as the downpipe was very restrictive.

I have now got a FMIC fitted and am getting 550cc injectors and 255Walbro fuel pump, so for my next remap I don’t want the downpipe to be the problem.

Current mods:
HYBRID fmic
APS Cold air feed induction
APS SR30 Turbo
Unichip (Mapped to Optimax)
Full Magnex de-cat exhaust
HKS Oil temp, Oil Press, Boost gauges.
Link AFR
