on a 1.6 xep engine,

decided not to bother with a z20let, just gunna ride it out for a year untill insurance permit a gsi or vxr.

so in the mean time i wanna get a bit more BHP out of the 1.6,

i have order

panel filter
vec c intake
deristricted my air box

a local place do custom exhausts and have quoted 300 for a full decat system

i am also looking to added some cams and one of the diblas replica intakes aswell.

so my question is do you think its worth spending 300 on the decat exhaust and what sort of gain do you think i will be looking at.
thanks
