Hi flow vs Cat delete

[arreola_2007]

Ive been toying with the idea of removing my cats being ive done that to every car ive owned since i was 16 and always noticed a gain but from what ive read some guys said they noticed no gains or even loss of torque?? i mean ill put up with the smell if theres a hp gain but not if theres a loss lol i know its double walled pipe but a local exhaust shop here said they could do it! And mind u i live in CO so no emissions! OR have u guys using Hi flow cats notice good gains! Let me know what u guys think any input is appreciated!

Buy headers with no cats and call it a day if that is what you want to do. Nice clean install and your Jeep will thank you

Plus guys are always looking for stock exhausts manifolds, so it shouldn't be a problem to sell them off and get some money back for headers.

Nope, if the tuner turns off the rear 02's you will FAIL the OBD ready test because the rear 02's will come up not ready.

On other vehicles? Have you tried on the jeep? I am pretty sure the consensus is if you shut them off you will fail emissions if they do an OBD check.

Jeep will be going at the beginning but yes 2 other vehicles to unsupported for emissions and you het a pass every time and MD does a OBD check. I quite sure the talent we have with the tuners here can make it happen. I think someone even did a thread on it where johan got him to pass by doing it.
