Hello all i am in dire n eed of some advice i just bought a new dc style header for my 93 delsol si i am trying to find out if the o2 sensor is going to work . on the original header it is at the collector for the down pipes but on the new one its on the first down tube about halfway down it would seem that if it is there it will make the engine run really ritch due to sensing only 1 exaust ports output any sugjestions if u are wondering what header i am talking about just go to ebay and look up delsol header its the $139 one ty ahead of time

I bought a OBX racing header that's the same way. It seems it is runnin a little rich, I have an air/fuel ratio meter, and it says the car is runnin normal.

Ty  i am prob going to sell it if i cant get more info on this thing i was very disapointed with the seller on this product he refuses to help me with my delema they say i should have asked  about it only prob is that they said it would work perfectly lol  Have a nice day and thanx again for the advice

it Should Work.. the DC header is the only good header that you can get for the Del Sol that is CARB legal. I am Seriously thinking about purchasing it myself, I just dont have the money yet. I have however put JDM Civic Type R strutbars on the upper Front and Rear, and a Coilover Kit for it. the best catback Exaust you can get for the Del Sol SI that is CARB legal is the Geddy SP. thats probably next on my purchase list!

Update, -- Greddy had released the EVO Catback Exaust for the del Sol --
