    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 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?

    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 ;)
