Remapping after upgrade

[Qw3r7y]

Hey peeps,
 
Just wondering if it\'s advisable to get a remap after fitting an aftermarket performance exhaust?
 
(engines on approx 5K miles)
 
Cheers,

Its worth getting it checked over to see if it has leaned your car out.

How much of the exhaust has been replaced?

Hello and Welcome as well mate.:yes

It\'s on a car I\'m looking at buying so I\'m not sure as to the extent of the replacement. It looks to me like a similar one to what I had on my old Rex (Sold it to buy a Porsche - Worst decision ever! Am currently rectifying that mistake!) so it\'s probably the entire system inlcuding cat back I think.
 
Was asking as if the guy who\'s had has been running it on that system for 5k miles and it should have been remapped how much possible damage could have been done? Don\'t want to buy a howler as I got lucky the last time I bought an FD considering i new nothing about them then.
 
Oh, and thanks for the welcome! :driving Been visiting the forum for years, just never posted before!
