dsgrntld187 Posted April 4, 2005 Report Share Posted April 4, 2005 I know they make 3400 headers for the Grand Am, and I know someone said they would fit, but does anyone know for sure? I think they said the exit comes out to the right instead of the center, but I don't remember. I want to get a set of headers for my Cutlass.. I'm going all out on the 3100 Quote Link to comment Share on other sites More sharing options...
Brian P Posted April 4, 2005 Report Share Posted April 4, 2005 The rear header has to be heavily modified to fit. Quote Link to comment Share on other sites More sharing options...
Vegeta Posted April 4, 2005 Report Share Posted April 4, 2005 if someone wants to bring me a w body with the 3100 in it, I can make up a set. I need to get some tubing and go from there (flanges are easy enough). Id probably need the car quite a while though, so I may just get a motor and swap it into my car for testing purposes. Not sure how many body styles would take the same setup but I want to work on this setup. Quote Link to comment Share on other sites More sharing options...

Vegeta Posted April 4, 2005 Report Share Posted April 4, 2005 You have to cut up the tubes and reroute them along with shortening them. Quote Link to comment Share on other sites More sharing options...
