Hey guys I am finally heading out to but my mufflers for my dr. gas x-pipe and 2 1\2" exhaust system. I can't choose between spintech sportsman streets or dynomax bullets. I want something that is super loud with a nice sound. Are the spintech sportsman streets loud I have heard spintechs but I don't think Ive heard this one before. I have never heard the dynomax bullets but I hear they are super loud. I have a 351 Windsor in a 1969 Mach 1. Send me sounds and vids guys. Once I have my exhaust system put in I will post some vids. I need responses as soon as possible. So i can jump on it because if you guys convince me to get dynomax's I have to order them whereas I can just pick up the spintechs. THANKS A LOT STANGERS!
