hi all,

would anyone know if the hks downpipe (for a my99 wrx) has a splitter between the main exhaust side and the wastegate side?

i couldn't find any pics on the net.

Cheers

no it doesnt. its bell mouth

bellmouth meaning they are joint both the exhaust and gate pipe?

no. open your mouth as wide as you can. thats how it looks like haha

lol, ok then, worthed to get a splitter weld on?

lol i dont get the difference wouldnt a bellmouth flow betteR?

no. a bellmouth causes turbulence. you want a splitter to seperate gases so they reduce the amoutn of turbulence after the exhaust of the turbo.

the RMS dump pipes are good as the wastegate side is slightly block to hold the wastgate shut as long as possible.

to clarify, you want a venturi splitter, not just a 'splitter'
