Anyone know the size of the nut on the downpipe to the exhaust. Should be 3 of them.

10mm on the NA. TT prob the same on stock manifolds

not 10mm I have a box of metric nut from 8 till 18 an nothing fits!!!

have ya tried half inch?

They are 10 x 1.5 iirc.

thanks jimmer top man.

mine are 14mm nuts

I have 14mm nuts and do not fit? I have 14mm bolts and the nut I have does not screw on it!!!

nuts and bolts are sized by the thread not the spanner that fits them.

Exactly.

I measured the stud with some vernier calipers before posting.......:surrender:

13mm fits the nut i have. but a 13mm does not fit the stud.

Imperial nuts !! you serious.No car maker has used unf or unc fasteners for years.Jap stuff uses metric fine mostly so thats why your off the pegs nuts wont fit.will be 1.5 pitch for sure.

i thought you were on about the nut size not the thread size why not try a pitch gauge and then goto and engineering firm they should be able to sort you out some nuts for the right pitch thread
