I took a hit in the exhaust, and it completely cracked the front header tube. The crack is all the way around the 1-2-3 tube where it joins the collector. There is about 1/4" gap now, I can't budge anything to close the gap. I know it is loud, but could this do any damage to the engine. I'm concerned with 2 areas...the O2 sensor is downstream and may not send a correct signal to the computer based on a bad exhaust stream, and secondly less back pressure, burning valves...old wives' tale?
I need to get this XJ ready for the next ECORS race in 2 weeks, I will probably race as is and find/install a new part later. Thinking about getting some header wrap or exhaust tape to try and contain some of the exhaust. Other than loud, think I'll be OK?

Crown bumpstops disintegrated, bumpstop extension fell out (construction adhesive will not hold a hockey puck in), front driveshaft yoke hit the downpipe tearing a nice hole in it, and cracking the header. That's how I think it went down.
