RB,
I used the 30" long with the 2 1/2" bore, packing and ceramic coated. I also faced the open side of the internal louvers towards the outlet. The sound was deeper and tickled my insides at first before I got used to it. I use earplugs when I drive and carry spares for my passengers. I was worried about the noise in my neighborhood too but have learned the guys who live around me love to hear the car. Ask me to rev a little more for them. I try not to be a nuisance with it. I don't let it idle in the driveway unless absolutely necessary. I leave many times on Sunday mornings before 6:30am for Super Car Sunday. No complaints except from my wife. I was at a parade with several other Cobras and was told by an onlooker that my car sounded the best. It was the only big block in the group but I'll take the compliment.
