I actually really like the sound of Flowmasters. I love hearing that DEEP sound that a big cubic inch motor thumping through a set of larger diameter Flowmasters makes. Anyway, back to these glasspacks......I've never ran them, but I was always told to avoid the ones that have the internal louvers protruding into the exhaust stream. They flow terrible. When I think back to the early Eighties, there was a muffler called the Sonic Turbo that was very popular and that's what I always used. I'm sure many people here remember them.
