cracking sound on the TSRM
well i have my exhaust for about a month now and im loving it
but my question is, yesterday after driving my car a couple of hours and when i park it(with the engine running) i was listing to my exhaust and there was a cracking sound coming from it, it wasn't a loud cracking but is noticable if you're standing by the exhaust. now is this normal????

when things heat up they expand. when your exhaust heats up, it expands too. This is normal, yours does it and mine does it.

Mine does it too ... and if you listen real carefully after driving th engine compartment does it too ... it's more pronounced if you park in a garage

Mine back fires because I have no resonator on my mid-pipe and I disconnected the TSRM muffler part and replaced it with just piping as some of you know. When ever you replace your exhaust system, in most cases and certainly mine, there are times when the backpressure significantly drops and then rises again once you step on the gas and exhaust fumes are pressurized as they try to escape the piping. When you step on the gas, pressure builds, and then when you get off the gas instantly, the area of piping that should have been filled with pressurized exhausts fumes is now in a lower pressure than the rest. This creates a vacuum if you will, and may suck un-burnt gasoline into the headers and mid pipe when it is then ignited by flame leaving through the exhaust ports. To my understanding that is why cars like mine, backfire. Hope that helps...
