I'm wondering if anyone did a port and polish to the OEM GT header? If yes, post a picture and cost for labor please Im interested in having this done. Thanks!
Now, I'm just wondering if the exhaust ports on the head are the same as the headers? If the heads are smaller after porting the header then it isn't going to make to much of a gain.
