It's usable, but i expected more...
It doesn't sound as "tough" as it should for a massive and powerful truck the T-series is.
Conclusion: It's not good... but it's not bad either...You can use it all you want, but for me this is not a sound tough enough for the T-series.
P.S. Just because i'm nice here's how it should be: https://youtu.be/jCWzPd9UgUI?t=1m34s
