NNBS 3RD Cat Removal

[NORCAL SS]

have a 5x11x28 magnaflow 3.5 inch in/out with resonator cut off and wanted a little more sound so cut off the 3rd cat and truck has the perfect sound now and also picked up a little power

 

 

 

 

I used a 12 inch piece of 3.5 pipe and welded it up

Did you MIG or TIG the pipe in place?, looks tight.

[NORCAL SS]

I told the exhaust shop to cut that cat out as well when they did my borla xr1.. Guess I didn't have anything to compare to power wise, before and after lol Left the resonator in place near the tailpipe since headers are coming in the spring. Don't want it too raspy with an offroad-y
