Spark Arrestor Sound Insert Kit

Nice piece

Make sure the spark arrestor is firmly screwed into the Sound Insert. I neglected to check this and had my spark arrestor back out and rattle around inside the muffler. To put this much effort into the machining, fit and finish of a quiet core/ spark arrestor is a testament to Graves’ commitment to quality workmanship. It significantly reduces the dB level of the Graves exhaust while still giving a better exhaust note than the factory pipe. You do notice a reduction in power vs. running with the Graves uncorked. That being said, there are still solid performance gains to be had running the Graves Full exhaust with the Spark Arrestor/ Sound Insert installed versus the stock exhaust. I just wish there was an option to run the spark arrestor without the Sound Insert.
