I got rid of the C/S exhaust on my CX-5. heat soaks super quick, let's hella dirt into my engine bay (stock box has a scoop), lowered my mpg's, changed my power band to high rpm performance which is nice but quickly waned with heatsoak. I live I TX and it's getting warm, that wont cut it, I'm also moving back to CA. I found myself often barely being able to execute pass at 80+. Also, when I removed my SRI, there were scorch marks in the housing (I have no way of telling if that was from one incident or over time), and around the inlet for the tube at the top, however I will say that the inside of the filter, after 8k was clean. Granted this is on a 2.0 CX5, not a 3.

. It does sound tight with my C/S exhaust (which I am happy with and seems to improved my MPG) If anyone wants to buy this for their 3 since it seems to work better PM.
