328i to 335i exhaust conversion, do I need a tune?

Emmmmms · 07-07-2019, 01:52 PM

Hi,

I have a 2013 328i that I recently purchased with a Dinan stage 1 tune already included. Currently it has the stock 328i exhaust but I plan on changing it to the stock 335i dual pipe exhaust.

Does anyone know if I do this conversion, will I need to re-tune my car?

Thank you!!

No, anything after the cat has a negligible impact on performance and thus doesn't require any tuning.

No need to tune it at all.
