I am not sure what you are asking for with an extension.
We just picked up a new AWD dyno, there is a shopping list of things we need to run across it. The axleback and combos of it with the intake will be done in the future.
On 2wd Mazda 6 turbos the axleback was good for ~6-7 hp.

CX5 customers are not typically looking for a weight savings when shopping exhausts so it is something we never measured between the OEM and ours so we do not have the data.
Quick update for people waiting. We accepted some pre-orders for the next batch today but have stopped as of now. They will be going out the door early March.
We will have some available to purchase when they go back live on our store on 3/11.
Thanks
We work in model revisions as things come along so the facelift Cx5 is something we will work on trying out fitments.
The current intake is the same so you should be good there. We are out of stock until ~end of the month of those.
Intercooler and charge pipes carry the same part#s are the...
We use mother metal polish here @ CorkSport for tough spots.
Normal cleaning with soapy water is what I personally use on my Mazda 6 Turbo exhaust.
