need help with greddy catch can size
 

im looking to buy a greddy catch but im not sure what size i need either 9mm or 15mm? i measured and i believe its going to be the 9mm but i just want to confirm before i place the order

thanks

gregs

9mm.

i got the 15mm one and i ended up buying new barb fittings and hose.

Thanks looks like I have enough time to place the order tonight!

Yeah, I was a dumbass and bought the 15MM one too.

im glad i asked, apparently the 9mm is now a discontinued part, so i was on a man hunt looking for someone that stocked it..the only place that i was successfull with is race roots
**have it on the way**

did you do what i had to do and get new fittings and hoses?

No hoses yes... new fittings... nah, I'm too ghetto for that. :( Metal clamps did the trick. :P

Bump thread... To reconfirm.. 9mm fits best...

Anyone know if the Perrin unversal catch can or the speed 6570 is 9mm as well
