u mean ur engine is turbo gsr rite?1.8 turbo should be at least using
2.5 inch if u want a bit of power.the std piping size for gsr is 2.25
if i'm not mistaken.

better u use 2.3inch piping n a S-flow muffler..its will help...

my advise, 2.5 inch with sflow type.all the way from turbo to muffler.Super silent killer.
