Does anybody know the size of the downpipe on the 99-00 si greddy turbo kit?

Has anybody added a test pipe or a bigger downpipe to their greddy kit? Did u see any HP gain?

 

think its 2"

Yes, it is 2"

 

atp turbo makes a v-band adapter for the 18g. Greddy used a hybrid mitsu/garrett for the 18g, the 18g is a t-25/t-28 exhaust housing, the v-band adapter takes care of the elbow and then do a dp for the rest. and you are done. Oh also if you are doing the dp i would port the wastegate as well.

it wont retain AC. its VERY tight in there, you wont fit anything in there AC compatible.

i can replace the lower elbow for you . 165$ with flex pipe for the lower elbow downpipe.

yeah, i am running it on my car right now. Really nice spool, and with the v-band it takes only seconds to drop the downpipe
