I tried searching for a while but I couldn't find anything, and my cat bolts are so rusted right now that I can't really measure them. Plus it's raining outside. I know the TL-S and the TL-P cats are different, and the flange that connects to the B-pipe is different. My question is, on a TL-P, are the rear cat bolts the same size as the front cat bolts?

 

I see that part 4 (front cat bolts) and part 5 (rear cat bolts) have different part numbers, but unfortunately it doesn't tell me anything about the size. However, they do use the same nuts for both front and back, so maybe they are the same size and pitch but just different lengths?

They are Pressed in. You would probably just be better taking them off and going to the parts store for some good bolts.

If i had to guess they are a 10mm

 

they are on my car...14 mm

 

That should be the socket size, the bolt size would be a 8 to 10

 

Yeah I'm gonna get them torched out and I'm getting new bolts, that's why I was asking
