Alright Guys,

I recently had a magnex exhaust from the CAT back and a K&N induction kit to my MY99 impreza turbo.

I was surprised to see that this has actually increased the amount of i miles i get per tank of petrol (optimax, as always). I used to get on average about 270-280 miles per tank, now with the mods listed above i'm getting 290-300+ which is a very pleasant surprise!

Has anyone ever heard of this b4, or could there be any problem, it just seems abit too good! (i know it's on the case on 20 odd miles, but we all know these cars are expensive to run!).

Any help appreciated,

Cheers.

The figures are pretty typical.

I will have to book mine in Pete, I only get 200mls to a tank of Optimax!

Maybe its just a dented fuel tank

Probably running really lean

used to get 300+ out of my olf my99 with normal unleaded. this was not driving like a nanny either. 80+ on motorways and using power to overtake on a roads.

exhaust stayed clean for alot longer, which from reading other posts suggest it was running lean, hence the high mpg

hope this helps
