dynomax race bullets

any one running the race bullets on a street car?volume wise what would you compare them to?being a fabricator by trade ive built several exhausts for my dart over the years. my current favorite set up is a 3" xpipe with dynomax ultraflows.however,i held off on fabbing the tailpipes until i knew how a 3" system would react with my combo.now that i know that it works well with my set up im building the tail pipes.just recently a friend gave me a set of race bullets and i was debating trying them.i just wanted some feed back so i could make a more informed decision .thanks
