For clarification, I have recently purchased an older 5 speed manual mustang gt, its nothing crazy at around 400hp but shes loud with aftermarket exhaust, long tube headers, and detroit rocker cams. What is the consensus on when I am driving my car and when going by a semi-truck and sometimes I downshift and full throttle it for the sound bouncing off the trailer similar to what you might do in a tunnel. Is it loud for the trucker? Can you even hear or care?

EDIT: Thanks for all the responses. To clarify my question, it was more of do truckers find it annoying or a nuisance when an annoying sports car like mine intentionally revs their engine next to them or flys by them to hear their exhaust bouncing off the trailer not if the truckers find my car cool as some perceived the question. The consensus seems to be that you guys dont give a shit because you either can't hear it in general or just dont really care about some guy in his sports car which I understand.

I was asking this cause if I had responses where you said its explicity annoying then I probably would refrain from doing so next to you guys similar to where I dont usually rev it next to other smaller cars to avoid startling them. Thanks for all the responses. Keep on truckin.
