is a resonator same as a coby? or is there a difference?

I have also heard that people say removing catalutic convertor makes better fuel economy. Is this true?

Hello everyone. I have got a 2 litre non turbo impreza (2001 model). I am wanting to ge the subaru sound. Will removing the cat give the subaru rumble. I dont want it to be loud. What are you experiences? What about leaving the cat in but putting a coby in?

nztintin - How many kilometers does your mrs car (20n) do with a full tank. Just wanting to know so when i do change the fuel filter i can compare it.

Taupo

I have reset the ECU and used 98 octane. Actually went through few full tanks using 98 just to be sure but still no difference seen/felt. The issue of lagg is only when stop start until around 2500rpm. When cruising and you put the foot down it is fine. How much are the O2 sensors?

Yes that car is triptronic. Also another issue is when you put your foot down from stop position, it doesnt seem to have any power until it gets up to 2500rpm than it goes fine. This only happens in first gear (triptronic).

The fuel tank capacity of a non turbo 2.0litre is 50L. Damn the reason why I chose a non turbo was because iw thought it would be chaeper on gas. Sounda like the turbo and the non turbo's nearly have the same economy!

I have just purchased a 2001 non turbo impreza hatch back for my sister. It has done 109000kms. The problem/amusement is that it only does 400kilometers out of a full tank of gas. I use unleaded 91. This car is a non turbo 2litre. I would have thought it would do more than 400kilometers of highway driving? Do you guys have any recomendations to what i can do. I have got all servicing done except: Havent changed spark plugs Havent changed fuel filter Does anyone here think fuel economy will increase greately due to changing fuel filter and spark plugs? How many kilometers would you get out of a turbo wrx 2litre on highway driving?
