Bolt size for exhaust tips?

[ScoobyDoo555]

In readiness for tomorrow, what is the bolt size (inc length) for the exhaust TIP clamp.

(forgot to order new clamps + the old ones are fine, although the bolts have seen better days!)

10mm dia and about 30mm in length.

 

However, if you use a conventional bolt the hexagon head is within the tube and is a bit awkward to get at and the OE fitting is a flat head bolt with a square fitting under, much like a conventional coach bolt.   I went non OE and used a stainless steel coach bolt about 30mm in length with a stainless washer and an aerotight or philidas self locking nut in stainless steel.  These self locking nuts can be re-used, unlike nylock nuts which won't stand the heat.

Don't suppose you've got access to Durametric? :D

Sorry, can't help with the Durametric. 

 

Have you thought of becoming a contributing member even for just 25$?  Every little helps and this site is a great asset to Porsche owners.

 

I might have given you the wrong answer as the M10 bolts are for the chrome trim.  The bellmouth joint between the final pipe length and the exhaust needs an 8mm bolt.  Here I used a socket headed bolt about 60mm in length with an aerotight nut and stainless washers.  You can get these socket headed bolts in Metal Work Supplies, Hereford, but they don't have aerotight nuts.

 

When you put this fitting on you will probably have the exhaust shield off to give you some space.  You will need to leave the fitting slack so that you can line up the exhaust tips for a balanced look from the back.  Although space is limited in this area, it is possible to tighten this clip when everything is back together, but you need to locate the bolt in a particular location to do this.
