Question power gained:TXS stealth back(catted) vs TXS TBE(catted) vs TXS stealthback (non cat)

Hey guys,

I have the above TBE with a hi-flow cat. Believe it or not I would like to go back to the stock STi axleback for the stealth effect.

So my question is the following how much restictive is the STi axleback?

Would a catless stealthback produce gains as the catted TBE?

By the way I also have XXtuning headers. Rest is stock.

How would the above result changed if I went to a new bigger turbo/injectors and bigger TMIC? How much of a bottleneck the STi axleback is becoming as you upgrade more and more?

Any input would be appreciated.

cheers and thanks for input.

Nick

I would guess with the cat and removing the axle back you would be giving up 5-10hp peak.

if you need to keep the cops out of your hair,
then it may be a very wise choice.

just for the record though, stock axleback rusts like a mother****er.
i was stunned when i took mine off.

I agree 5-10hp with stealthback plus cat. But do I gain that back with stealthback no cat?

I am guessing this is why the 05 axleback is like painted/coated black. To avoid rust.

I may just have to foot the bill to make some dyno/tuning runs.

Keep comments/input coming..

Thanks

You are running a catless stealthback?
How is the noise level?
How is the the smell?

I had the catted stealthback on my WRX and noise was pretty much the same as the stock exchaust.

Thanks for input.

A tad louder than stock. You will not draw attention from cops if that is what you are asking.

Yup unwanted attention is the key here.

Thanks
