Hey everyone!

So I have been wanting to knock off my Cat and run a straight pipe instead. Atm my car is running 326.3rwkw@15psi, by removing the cat, how much extra flow/power do people usually pick up? just wondering

oh ps. I will be retuning if I decide to go ahead with the pipe

Do you care about the EPA laws over there? Or are they different is SA?

In Vic if you get done with no cat they will throw the book at you. 10K+ fine from memory.

Just fit 100cell 4-5 inch high flower...

Stinks at idle too, when your stuck in traffic it's the worst

I am curious as well (not that I'm knocking out the twin cats I already paid for). What would the power difference be from 100CPI 5 inch to no cat at all with his mods?

What are the specs of the cat you have currently?

I dont think it is strictly measurable. Every car will respond differently to removing it.

From what I've heard a 100cpi cat wont pass EPA emissions testing anyway...

I have twin 100cell 3inch might bash them no point on even having them

Currently I have a 5 inch 100cell cat in my car, just looking for peoples thoughts. I'm waiting for a mate to pick his FG up tomorrow from our tuner which has been done without a cat.

I know this hasn't got anything to do with our group, but a mate of mine knocked his cat out of his GTR 34 Skyline and the before and after tune showed a noticable difference in power,throttle response and overall flow of the vehicle.

As it would
