Glad to hear u got that off finally! I don't see how that bolt held up to that much force.
Seriously. The hex portion is now 12 point, but the rest of it looked fine once we got it out. I think the bearing being bad just overheated it and made it hard to get out. The bearing had no grease inside and smelled really burnt. It also came out in a few pieces. I have a picture on my phone, the bearing race was fractured half way around its circumference.
Ricky it's an 01 S4. We straight piped it a while back, it sounds good.
