Mechanical Problems & Technical Chat
So I have a 2012 Civic Si Coupe that I just purchased. It has an AEM CAI, secondary cat delete, and Greddy 70mm exhaust.
When driving spiritedly, when I shift into 2nd from at or near the red-line of 1st, it grinds until the RPMs drop.
It also doesn't even feel like it is going into...
