I have few questions here. I got a Greddy 4-2-1 header for my 95 LS acura, the car is a beater. The beater will also get a cheap egay intake w/K&N air filter soon. with out a full exhuast will the headers give any extra ponies? (dont what a loud beater car) or do I need to buy one to go with header? also I have a 97spec ITR B18C, could I put the LS Header on this motor and see a diffrence over the stock cast manifold? I ask this becuase I think the stock manifold has a bigger collector then the Greddy header has, and I think that will hurt me at top end. This car is mostly for drag.
