Do you mean the bolts to hold the down pipe to the turbo?? If so they are M8x1.25. I think...

I went to home Depot and just sat in the bolt section until I found them.

On a THDP the above post is correct, prolly around 25 or 30mm in length X 4. The stock DP uses 2 only and I believe they are 10mm X 1.5 pitch thread.

Socket caps work much better for the THDP as well, I had used hex heads for a while and they were a pain.

 

[Kevin Turch]

Thats why im getting new ones , mine are getting kind of crappy. With the socket head ones, is it easy to get a wrench in there?

 

[The Radius Kid]

The socket heads are the ones Terry supplies with his DP.They use the Allen key style drive.Very easy to get in.

If you are trying to use a 3" downpipe, the hex head bolts will likely contact the side of the downpipe. You'll probably need the allen head style.

Hex heads fit, but you'll be a while getting them in due to constrained positions of the wrench, and a thin wall socket won't fit.
