I agree but for the price it doesn't flow any better. As Däs Schmoo put it "DC Sports is a good alternative to the OEM piece because it is cheap and it is smog legal."
That's why I asked him if there was a problem with his OEM part because to tell you the truth I would have never replaced mine if it didn't rattle. And the only reason I didn't replace it with OEM one is because the dealer wanted $500 for a new one so I picked up a DC Sport. Don't get me wrong I'm not saying it's worse than the stock exhaust manifold, but it's definitely not much better. If there's nothing wrong with his stock manifold and he's looking for power then I would definately look at something other then DC Sport, but if he had the same problem as mine and just looking for a quick fix to get rid of the rattle then for the price DC Sport is a good alternative.
