DC sounds like shit.
APEXi doesnt give a good amount of hp either.....its an exhaust system - they all give just about the same. like 2hp.
the quality of an APEXi unit is better, however ive had my ractive muffler for a year and its still in fantastic condition - i paid $100 for it and $120 for the piping and ive had the piping for 3yrs....
so i guess i got more than i paid for.....
