ppeters914 Posted February 12, 2009 Report Share Posted February 12, 2009 Get one of these. All of the performance advantages, cheap, and last forever. None of the disadvantages: noisy, expensive, rusty, loose, leaky, hot. Early L16 from 510 or 521 L18 from 620 I'll be going with one or the other when I swap in a W53 head and SU's. These are all 4-2-1, correct? All square port? Any difference other than the L18 looking beefier and having that (EGR?) tube? Thanks. Quote Link to comment
Phlebmaster Posted February 12, 2009 Report Share Posted February 12, 2009 There are no differences between the two other than the EGR tube. I used the L16 one on my W58 round port head and it works fine with a square port mani gasket. I switched to the L20 mani for the 2" exhaust. :D Quote Link to comment

Oh, wait, maybe that was by design to create necessary back pressure....yeah....right....:rolleyes: Quote Link to comment
