If I wanted to get rid of my dump valve... I need to bung/ block 2 pipes up...
I know these can be purchased...
But what size bungs do I need to get...
At the moment i'm running a standard ver 4 STi dump valve...

I've been told there probabley 25mm...
Anyone help...?

 

Bttt anyone. . .

 

get your ruler out

Have now cheers mate... just don't like taking things apart if they ain't broke...
Oh well... car is now soon to be dump valve-less... lol
35mm... good job I checked...

 

If you don't like taking things apart when they aint broke why are u removing the OE dump valve lol.

 

Because with a engine spec like mine... I think sound wise... it'll be the icing on the cake...
Just curious to see what it'll chatter like... lol
