I currently have the Injen exhaust on my car. If I went back to the oem exhaust, will I notice a dif in performance? I have Kinetix cats I'll be keeping on.

 

Randy - Hows it going...

I don't believe you will see a noticeably performance increase going back to the factory exhaust. However if you removed those: Kinetix cats . I believe you would see some noticeable performance increases. Without that backpressure the SC is dropping boost. I have seen this on the dyno with (2) SC G's run one after another. One unit was factory exhaust and the other had Borla + hollowed cats.. The factory exhaust produced 11 more HP. Of course this is just my personal experiences and is open to interpretation.

 

How ya doin' dude! My main concern wasn't gaining any more power, but losing it. I was thinking about going back to stock exhaust cuz this Injen exhaust is wearing down on me. It's constant droning and fiberglass blow out issues have taken their toll. So, you are suggesting removing the cats all together? Problem is, I don't have my stock cats anymore. Well, we'll see. Take care bud and have a great new year....even if it IS raining!
