Decat or Freeflow???

[E46arc]

Hi ive heard a decat will improve my performance, throttle response, and fuel economy, and as i have an auto, a better throttle response is needed.
my question is what will improve all 3 of those factors without making my car sound like a common citi golf(tractor).... so decat or freeflow?

I say get a decat.. its awesome.. I've done it to my 330i and it runs smoother... it picks up speed quicker etc.. i say go for it. :thumbs:

i would decat with an auto box i know the 6cyl tend to drone in the lower rpm with a free flow...

decat is the best way to go if you not going to tune it after...

I would also say decat and replace with a resonator box.
Then maybe put a set of branches as the cats on the manifold will def be blocked by now. You will need to install cat foolers after though, not very expensive. Then chip it. Consumption will come down and you'll have quite a nice tone. Keep your standard back box though. I tried 4 different back boxes, stock was best.

@Andrew I had N42 motor. Cats were on the manifold. I have a pic of them somewhere, will try find it.

@E46arc. Viper branches for the 318 fitted at Powerflow cost me R2500.
