Xnke Posted January 9, 2009 Share Posted January 9, 2009 Does anyone know who makes or made this header? There are no markings, and i know that OTM, back when he was on this board, had the same header. Both my header and his were found an L26, the primary tube diameter is 1.5", the secondary tube diameter is 2", and my collector will merge the 2" sections together into a 2.5" exhaust.

Daeron Posted January 12, 2009 Share Posted January 12, 2009 looks like an MSA 3 into 2 header to me, if not MSA then just another generic one. Quote Link to comment Share on other sites More sharing options...
Xnke Posted February 26, 2009 Author Share Posted February 26, 2009 Well, the MSA header is apparently a Pacesetter unit and does not have the 90* bend near the bottom. it's just slanted back about 30* from vertical. There are a lot of these out there, but it seems that no one knows where they came from... Quote Link to comment Share on other sites More sharing options...
jknc90 Posted February 27, 2009 Share Posted February 27, 2009 Whats the tube on the #2 runner for? Quote Link to comment Share on other sites More sharing options...
brokebolt Posted February 27, 2009 Share Posted February 27, 2009 Whats the tube on the #2 runner for? That would be used for a Heat Riser tube that pulls hot air off the exhaust and into the fresh air inlet on the air cleaners assembly. This was used on carb cars usually and on the later SU set up for the Z version. Bell tops and bucket tops both used this heat riser set up, early bell tops had nothing, later bells had a winter/summer selector lever on the inlet snout you had to manually turn under the hood and the later bucket tops had an auto set up that did all the "hard work" for you. They were used to heat the air coming into the carb for cold starting and cold weather driving. Quote Link to comment Share on other sites More sharing options...
jknc90 Posted February 27, 2009 Share Posted February 27, 2009 Thanks brokebolt, my carbs/aircleaner don't have anything like that. Quote Link to comment Share on other sites More sharing options...
