Exhaust bolts - Sizes

Greetings all and hope all is well. Going to install some pre cat test pipes in 88 TR. Would like to change out nut and bolts. Does anyone know size and length of the bolts going to manifold and to the cats. As always I thank in advance for any input my TR brothers.

I´m far away from my garage but the diameter is 8 mm with 13 mm head, length I don´t remember, but this you will see when you install. 40 or 50 mm? not sure

 

I too am installing new bolts between the header to the pre-cat and the larger bolts for the cats to the pre-cats.

Did any one ever do a cross reference of those bolt sizes and the springs?

 

I got the springs to reuse. Just want to freshen up the nuts and bolts.

The bolts are 10 x 75mm, thread pitch 1.25.

 

That is for the main cat Brian.

 

Thanks. What about pre cats ?

8 x 90mm

 

Thank you All!

 

Thank you. Much appreciated.

Robbie... Did you buy another ***** to romp on?

 

Was up brother. Boy I miss my *****. Negative. Just wrenching on my buddies car. Just wrenching on the car gives me great satisfaction.

Would love to have you back in here more often and back telling stories of your exploits with your *****. That white one in Washington sure looks nice... but then again, I am partial to white

 

Thanks brother. The white one is nice. would love to get my hands on that *****. Priced out of TR's. B*tchless I remain. Lol.
