Exhaust Change Need Retune?

[Hungryhippo]

hey guys.new member.

just fitted an exhuast manifold and dump pipe to my car.previously i had a cat back exhuast and had the car tuned with an e-manage to run 1 bar boost.

should i have the e-manage re-tuned or will it be ok as it is?

I would suggest to have the air fuel ratios check and adjusted if needed.

I am guessing that additional flow could require/use a little more fuel but don't mind being corrected!

if you noticed a change in spool times with the new "manifold" then yes you will need a new tune..

$50 dyno run will tell all

Generally yes
