Has anyone gutted their cat
How does it sound and does it feel torquier

Yes (when I had my 2gNT).

You (NTs) actually lose torque and gain very little at top-end. NTs need restriction (back pressure) to create torque, which is critical in NTs in their low to mid-range. That is why you do not see any 2gNT owners (the smart ones anyway) runnging anything bigger than 2.5". Anything larger, your low to mid-range will be the cost you pay.

IMO, go with an aftermarket High-Flow Cat (2.5").

If you're planning on going turbo, 3"w/straight pipe is what I would reccomend.



Please search next time.

not to be ignorant but isnt a high flow basically the same as gutting a stock

 

[top_end95]

No.

If you were to gut your cat, it would be completely hollow. Whereas the high-flow is not, still same stuff inside just with less restriction.

depends on whats done to youre car with enough upgrades you wont lose low end i didnt.

but if youre pretty stock i wouldnt do it without an engine management system you can lean out youre fuel and burn youre pistons due to excess gas triggering the sensor behind the cat causing fuel cut.

I just put a high flow cat on my car. It feels a little better but it sounds like ass when it's cold out.
