Decat on hatch impreza
 

I'm not sure on my hatch whether I need to buy a downpipe only or another part of the exhaust also to remove the existing cats?

also upgrade the standard air filter,

but what ever you do... make sure you get a re map once it's done.

as the car won't like the change in set up on a std ecu/map.


speak with Kev at Scoobyclinic in Chesterfield.. not that far from you

Thanks. But the info I need to know is what bits of pipe I need to buy in order to fully decat the existing standard system.

It currently has the prodrive exhaust btw. I think this is still 2.5" diameter.

Tom
