Not a poxy Renault
Put my cat back on a couple of weeks ago and have managed to convince myself that the power delivery is different. Basically it seems as if there's a bit less power below 4.5k, a bigger kick at 5k and a touch more power above this (with the cat on) mods are inlets matched and remap. I'm thinking that the cat design suits the engine at higher revs better than the straight through, smaller diameter decat. Anyone have any thoughts? Anyone have any before / after dyno graphs??
