Miles

I've tried to buy second hand but they all have the same crack on manifold, the engine is very restrictive because of the cats so would be nice to free some extra bhp for all the hassle the car has gave me

Someone please shed some light on putting a decat manifold on my a3 2.0fsi , will the car run ok or will it need a remap to delete lamba etc, my original manifold has cracked and a genuine Audi one is £500, seriously contemplating scrapping the car bin absolute nightmare
