I deliberated this choice for a long time...header vs manifolds...straight dump vs angled dump. Finally, I just decided to try it and ordered Dorman 2.5" straight dumps on my 1972 GMC 2wd LWB 350/350. My small town exhaust guy did a beautiful job and I couldn't be happier. No noticeable change in performance compared to the long tubes that were on it. No leaks and no pipe ring tone to the exhaust. My reading seemed to indicate it all depends on the ability of the installer. I was very fortunate.
