dang, didnt know that about the epa laws.

and maybe the 2.5 was bigger and required it. i swore it wasnt. i know my 20g which may be a tad smaller in phyiscal size didnt need the air pump delete. it's possible i could be wrong and it is needing to be removed. but i could have sworn it would fit. AUS cars may also be a little different too, if they are RHD. that i'm not sure of. could be that the air pump was modified to make it work, but i'd have to double check on that. back when i was working cobb didnt have the greenspeed so it's possible most already had the air pump deletes. it's been a while.
