what kind of bolts for exhaust header?

[grandinj]

Hi Fellow PCXers!

So the person who sold me my bike didn't tighten the aftermarket exhaust on properly, and the header pipe fell off on the freeway somewhere.

So I need to refit the original exhaust, but the bolts are (clearly) missing.

They look like 12mm bolts, but what kind do I need? Stainless? Nylock?

And do I use threadlock compound on them?

Thanks, Noel

Stainless steel bolts… Stop obsessing about it and just tighten them down. If it worries you check them once a month, you’ll give up after a few months

Are they not nuts on the header? Think mine are M6

The originals on mine (2016 PCX 150) are a 7mm chrome-plated tall dome nut with a flange.

Very weird size, struggling to even find 7mm stainless nuts here.
