will adding twin exhausts require mapping?

[slick91]

hi im about to fit a twin exhaust set-up on my 1.9 cdti sri seen this in a how 2 using original silencers, will this effect the mapping , will i need to do anything i.e. remap, cheers

No. If done properly the right back pressure will be kept with smaller diameter bores after the y like the stock twins on a YH over an SE

No as its a diesel turbo it does not require back pressure as such.

Z22SE is the petrol 2.2 and Z22YH is the newer 2.2 petrol (Direct) which is fitted with a twin system. You wont have any probs mate as big sig said. Some CDTi owner dont even have any back boxes just tail pipes.
