i'm running a dc jdm 4-1 header with a omnipower test pipe. the only bolts that fit through the holes on the collector flange were 13mm's. my question is, which nuts and washers do you use? obviously i'm using 13mm nuts and washers but the holes on the flange on the test pipe are HUGE and the nuts and bolts fall through and then come off. i've replaced them several times and its very annoying. any help would be much appreciated!

 

dude those bolts should have springs if they're missing you gotta get em thats probably why they slip thru

 

were they supposed to come with the header?? i keep hearing about people using springs with the bolts on these headers but i sure as hell don't have em...

No, you reuse the stock springs. Just find washers that are large enough not to fit through the holes, and use multiple sizes if you absolutely have to.

 

i'll have to go and buy new oem springs because i'm pretty sure i don't have them anymore...unless they're still on the oem header.
