Came upon a deal at the local mod shop - Tailgunners for $200 says hes tired of looking at them on the shelf. Currently running samson shorties with ground pounders but need to build some back pressure. Any ideas on how these do without baffles and what kind of power they can produce vs my shorties? I like my samson's but turned the tips out instead of down and they're LOUD!! Plus my tips are looking mashed from scraping them in curves and I'm thinking either aspeed pipe or this.
