Hi,
So after having my CX9 for exactly 1 year and after ~13k miles I started my modifications on it.
As there is NO aftermarket support for my car I took upon my self to creat my parts.
First thing first :
A 3" catback system with straight threw muffler, I went to a local muffler shop, brought my dynomax ultraflo 3" in 3" out muffler, and after creating my mid pipe and getting rid of the 2nd cat and resenator, I placed it in the place of the stock bathtub in the back.
A small detour needed to be done around the rear diff, then 2x2.5" outlets
Once installed, a deep nice tone can be heard, no drone at all, as I kept my stock DP turbo spool not much can be heard.
If I pilb the throttle few times, you can hear some crackelz in the exhaust, no back fire or loud sound can be heard ( thx to the stock cat).
My gains from it : faster spool of the turbo, nice sound and strangley cooler water temp ???
I know it sounds weird, but my water temp now is always below 90* on the dash.
Once I go home I'll find a way to upload my cellphone quality pix for all ya.
Next modification is :
1- catch can.
2- aluminum IC piping with heat DEI gold tape.
3- some kind of heat barrier between the rad and the intake manifold, as my IAT Always high 2ndry to the IAT sensor being just behind the rad.
