Which cat back, would help with fuel economy and performance?
Sorry I know there's been a bunch of threads on exhausted, but I haven't seen anyone speak specifically about better fuel efficiency and hp gains. I'd there a cat for better hp gains? I've got a 2001 Nissan Maxima automatic,( I believe my catalytic converter is currently bad but that's besides the point). All real input is appreciated!

If you're looking for MPG help- driver adjustments or joining a shopping club like Costco(for lower gas prices) are your best bet.
For example: A $60 K&N filter(which is said to improve MPG a few percent) would take months to pay for itself under normal driving circumstances.

Surely any catback will improve fuel economy because its freeing up horsepower as opposed to adding it. Yes, noise does increase too. Of course the lead footed among us may completely negate those gains for other reasons, but gentle driving on an aftermarket catback system should produce better economy than OEM.

The OEM muffler has a flap in it that stays closed which helps with low end torque. Once enough flow is going through,it opens up to reduce restrictions in the chambers.
If you are looking to improve your MPG, focus on a tuneup and maintaining tire pressure. You will get better results for cheaper.

The OEM system is so advanced, you would need to buy the Cattman 3" catback to see any slight improvement and your return on investment would take about 5+ years to balance out.
