What is needed to be done to remove my cats? New headers..or what goes there to replace them?

anyone?

 

the easiest way to elimintate your cats is to just go buy an off-road h/x-pipe from JBA or something similar and run it from your stock exhaust manifolds and bolt straight into your mufflers. the only thing is that you will need to get a programmer (SCT works well) and have it programmed to shut off your O2 sensors or you will have a check engine light. also, without that tune, you will read a FAIL when you try to get it inspected.

 

Thanks... that's what I was just looking at..Like a offroad H pipe. Wasn't sure if I had to get the whole H just to take off the cats but it makes since. Do you think there will be a power gain from removing the cats or will the H pipe itself give me the power?

 

on the older stangs, the cats were pretty restrictive but on the 05's, they actually put hi-flo cats on stock. From what i have been told, on the older stangs, eliminating the cats and putting on an off road h-pipe will give you somewhere around 10-15HP...which really isnt bad for only 150-175 bucks.
