Che,
Well I received the new style headers & I am disappointed in the new style flanges. The flange transition to primary tubes is the worst I have ever seen, (I used to sell headers at a warehouse distributer speed shop) also the collecter to secondary cat pipe 3-bolt flanges are thinner & have elongated universal style bolt slots not oem style holes. Oh well I need the dual O2 sensor bungs per header for my 2000 Boxster so I guess I will have to give up some exhaust flow due to poor tube fitment to get the O2s on the header. I shipped them off right away to get them ceramic coated inside & out for $170. This will retain more heat inside the headers to bring O2 sensors up to temperature quicker & limit radiant heat to engine compartment. Headers came back from ceramic coating & I finally have time to install them, sold my 97-99 style TopSpeed headers for $100. New headers are harder to bolt to engine due to tube routing but I get it done then realize the
O2 BUNGS ARE ON THE BOTTOM of the collector facing down & there is no way the wires are long enough to reach the connecters. The bungs must be on the top of the tube facing up for the wires to reach not to mention to prevent a loss of ground clearance. As I start unbolting them to put my stock maniflods back on I notice the
PASS. SIDE DENT for engine clearance is in the wrong spot & has no effect other than to block exhaust flow. Great I have $400. "invested" in useless ceramic coated pipes & I just sold the last set I bought from you.
