I actually commend SLP on there design, it is loud as hell outside the car, but inside it is not bad at all. I drive on the highway a lot, I have an auto so at 80mph, the rpm is just above 2400, at 65 almost exactly 2000 rpm. There is virtually no Drone, I mean you can hear it, but it is not objectionable at all. I do notice if I then put the window down, I can here the exhaust bouncing of the barriers. This is all with an O/R pro-chamber and stock manifolds. On normal roads, cruising around is fine, if you don't get on it to hard, it's not to loud. You really do learn to control how loud it is, The best is driving in the city (Boston) between the tall buildings, if you romp on ot, the echo's are awesome, and it'll make people jump, lol

I Have the ORX and LM1 and yeah youll be heard everywhere, mine gets a good RASP at 2500rpms every time, it sounds like a old muscle car up to 2000 and 3000rpm and pass 10 second dragster, u can control it though

Now I really want to swap out my 40 series for some LM1s! My current setup sounds good, but it is not loud enough for me....I LOVE loud beasty sounding V8s lol....So I guess, that'll be next for me in the never ending cycle of Mustang modding!
