OBX header installed some Q's - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I just installed an obx race header for my 96 240sx. The only thing i dont understand is it sounds soooo loud like a open header car. Could this be that i didnt tighten the exhaust to the header good enough? I notice there is a gap in between the header and exhaust so im guessing thats whats making all the loud noise. I also wasnt able to screw in the egr tube since it doesnt match up perfectly and my second o2 underneath the car doesnt fit either. Could this be the problem? If it does turn out that i didn bolt the header to the exhaust correctly and retighten it would it make the car sound more smooth and raspy rathere then that open header sound? Any help will be great, thanks.
