The exhaust note had an odd twist on my car. Upon inspection of the exhaust.. it turns out the bolts that clamp the ball-looking-joint area to the cat loosened up quite a bit. One of the bolts managed to fall out on to the road somewhere.

Anyway... is there a specific part number or size for this bolt? It looks like it screws and tightens to the clamp piece. If there isn't a specific part #.. any specific nut/bolt I could replace it with?

Thanks.

If you are talking about the joint at the rear of the cat the pn for that bolt is: 1636152

That sounds like it might be it. Where did you find the part number? Just curious so I can see a pic to verify.

I cross refrenced the part labled 9 with my parts manual.

Yup. That looks like it's it. Thanks for the info/pic. I appreciate it.

The only confusing thing is... the bolt looks like it should screw in in the opposite direction.

I can tell you that mine bolts back to front, with the nut facing the front of the car, like the pic.

I think he has dual cats so its a different bolt..its pretty a band clamp bolt. Shoebox proly knows a part number for that.

mike95z28, dual or single cat?

mike95z28

Single cat.

I tightened up the remaining bolt.. I don't remember but I tought it threaded front to back. Could be wrong.
