Here's a picture of that torx bolt with the downpipe out. You can see the ledge that exists if trying to access the bolt from above; reinstalling would be tricky. Much easier to remove that bolt and install the turbo blanket with the down pipe removed.I was in the process to install it this weekend but the T30 torx bolt kicked my butt.
yesterday and today, I only ended up installing my Roush intake and ran out of time to install my JBR short shifter, shifter and bracket bushings.
I read trough how people took off that damn bolt. I guess I'll try another time.
