Like Bill says..... it depends. But in general these should be a benefit over the 38mm version to 3.2L and up and maybe even a highly tuned 3.0.

The choice of 1-1/2", 1-5/8", and 1-3/4" primary diameter has been debated and covered many times. Headers in these sizes have been readily available for some time, if you're willing to go without heat. Of course there are a few aftermarket heat choices but IMO none quite as elegant as a factory style heat exchanger like the Eisenmann or SSI.
