Hi all,

Recently changed my Prodrive exhaust and centre section on my RB320 and replaced it with a Cobra non resonated system, 3" bore. Having changed it I'm not sure whether it is just my imagination but I feel the car doesn't pull so well through the gears. It just doesn't feel as quick but not sure whether it just me.

Just wondering if anyone else has experienced this?

Thanks

 

Mapped?

 

No totally standard...

 

I think it will be the 3" bore, car probably needs a map tweak to compensate

 

I'd say it needs a map going from 2.5" to 3"

 

Is it a turbo back exhaust No cats?,if so It Definitely Needs a map mate.SJ.

 

Hmm, so it would lose power then going from 2.5 to 3? How much power we talking?

Also, what map would I need?

 

EcuTek remap would be a good choice imo

 

Yup will need a map, less back pressure I believe

I just switched from equal back to standard headers, made a hell of a difference on my spool time and that's before I have had a map tweak
