Only say that cause nitrous is easier to remove than headers if need be.

you sure don't need the headers to do nos !!! but if you what big gains need them !!!

some people say this cars don't hold a lot of nos blah, blah,blah . Its not because the motor its weak or the tranny wont hold , its because the car is nost built or programmed for that and since we don't have any source of tunning theres not much more we can do , ive seen this cars getting hit by more than 175 shot but the ecu start to do all source of arrangements to prevent this event from happening starts riching the mixture badly to the point that you cant do a lot just my two cents.

The only thing adding headers will do is void the warranty on the exhaust system. If if doesn't pull a cel your good! Trust me I know because I did my research with Lexus whenever I was testing the first set of headers ever successfully made for the ISF. Nitrous though will void it for sure.
