Thinking of switching to catless, but is it worth it?

Yiruna · 04-29-2018, 01:02 PM

Looking to maximize the efficiency of my car for the upcoming S55 battle. But not sure whether or not it's worth it to swap out my Catted DP for a catless. (If I were to, I'd probably sell the Catted DP, it'd Fabspeed)

I'm going to go PS2 turbo but I don't know if it's worth it if the gains are minimal.

Thoughts?

More power, better sound. Smells bad. Is it worth it? Not for me; but why would you care about others' opinions?

But how much power really? Is it that much over Catted to be really worth it? Fabspeed is already high flowing as is

100% worth it (I installed my catless dp yesterday

)

100% sound / cheaper / less restriction
A little smell but who cares, run some E85 for less smell

And dont idle with your windows down for more than needed

No power difference between a high flow cat and catless on these cars at any power level the stock fuel system can handle.

Advantage is price / sound if you prefer the catless sound

You’ll see very minimal power difference between catted high flow and catless.

What about for HPFP upgrade and on Pure Stage 2 turbo?

Go catless since you are upgrading your turbo

Only if I had my garage detached from my house, I will go for it.
So that my wife will not complain about the smell.

If you are free of these concern and don't mind your car getting loud as f***, DO IT.
Catless DPs cheap compared to catted ones.

Better flow with minimized back pressure. Awesome especially if you are tuning yours with bigger turbo or just ECU remap will do great job.

DP is must bolt on if you go bigger turbo. If you are not really making any mod and just changing DP, it would not worth IMHO.
Power gain is not considerable (Fabspeed claims 21 hp and 36 lbs/ft increase with sports cat but no claim has been shown for any cattless option from any manufacturer).

Gain will be loud cold start that will blow alarm of the car parked beside you haha.
