DAW Posted October 20, 2008 Report Share Posted October 20, 2008 1 5/8" primary tubes (most 240Z-280Z headers are 1 1/2" tubes, which are too restrictive for a large displacement L6, or for road race/high rpm use on smaller L6's). There is 17.5% more cross-sectional area in a 1 5/8" tube than in a 1 1/2" tube. The only good Y-pipe I've seen on factory-built L6 headers is the Nissan Motorsports version which blends the secondaries nicely. I am not selling/shipping these with the restrictive Y-pipe supplied with the header, you are far better off running some extended secondary tubes then a Y-pipe made by a competent muffler shop, fit to your car, or a Flowmaster Y-pipe. Header is sturdy and well made. Square port for E31, E88, N42, or P90 heads. Local pick up is welcome, $100 cash. Will ship to lower 48 states only for: $25 West of the Mississippi River; $40 East of it. PayPal only (except cash if picked up). Call or e-mail me for my PayPal address.

agentalpha Posted October 21, 2008 Report Share Posted October 21, 2008 (edited) I might be VERY interested. May I see pics of the worst rust/flaking? I would suggest local pick-up, but have no idea where you are. Good info in a "For Sale, local pick-up" ad. ;) TY! Edited October 21, 2008 by agentalpha Link to comment
