I posted in the QR section but maybe it should be in here. I'm new to NICO and just bought my first Nissan(04 spec v). Any suggestions for which header I should get? I would like a 4-2-1 style and I would like to get rid of the second cat as well, or at least get a high flow...I already have a Greddy EVO2 cat back and AEM cold air and looking for a little more power. Thanks, Damian
