Anyone know of a video or sounds clip of the spintech 9000 muffler with the rest of the exhaust system stock? Couldn't find anything on YouTube..

So quick question about the infamous 4.0 header crack...
Can driving with a cracked header cause any adverse effects to the engine? I know there is a balance of pressures and air concentration sensing going on in the system, but will that damage any internal parts? I've known Jeeps to be driven for many years with a cracked header with no problems but I can't help but think it would affect engine life somehow.
Thanks for any input in advance.

Hey guys,
I'm replacing my exhaust right from the donut back this weekend. I was wondering if the old donut manifold bolts / o2 sensor are usually are stubborn? Anyone got some tips?
Thanks

Not sure if its been covered or not but what size is the front pipe off the manifold? I know the cat and all after are 2.25" but I was wondering if the front is the same cuz I'm looking for a header and want to know if ones with a 2.25" collector will bolt right to the stock piping.
Thanks
Thanks

I keep getting the P0420 code and the u2 sensors have been replaced. I'm pretty sure it only throws the code at idle because both times it lights up I am idling.
Other than the o2 sensors, there isn't much else to throw this code other than a bad converter is there?
