Title: KA24DE HEADERS
Post by: matmat on Oct 20, 2010, 04:22PM

Hi all i have found some HI-tech headers but the outlet is only 1-3/4. is this ok as i thought it would have to be at least 2" to 2-1/4 for decent power gain i know you still need some back pressure but just thought this might be too restrictive.
can any one help?
thank you

I got obx racing R series headers from the states for under $300 landed to my door.

42mm primaries, 47mm secondaries and a 2" outlet, and all mandrel bend, hi tech seems pretty shitty.
