downpipe

What are good downpipes for an acura rsx base model? Ive seen a few but not sure if they are decent products. Also how much do you think it would cost to pay a place to install header and doenpipes?

Either just get a DC Sports (cheap and good gains) or TODA (handmade and $$$) racing header (illegal) or spend the money elsewhere, on a mainly stock engine, the K20 engine doesn't really need headers or exhausts for gains as they're good from stock.
