[SilSweet80SX]

my outlet extension...i know some of you have done this, what kind of gains did you get? im assuming around 15-20 rwhp.



thanks for the input if there is any:ylsuper

i dont know of the gains but i boubt that much. but i do love ur s13. i cant wait til im done my s14 KAT project to get an s13 with SR and silvia front end.

I know the down pipe gives about that much but the extension I believe only frees up a few more. Still worth it for performance and breathability.

is the extension used for a 02 Sensor? or EGT sensor?

[SRdave240]

O2 sensor.Which one did you get? Greddy?
