Quick update. I was going to clean the exhaust out but i found that they muffed up the wiring for the gauges. I ended up fixing the wiring and plumbing but need to finish up the oil and temp one. It is giving me a issue. If you watch my vid you can see a really good spot to drill into the car to run some wires for your audio equipment or for fuel pump wiring.
