MoJoJoe 46 Report post Posted April 14, 2014 Whats the difference between the shorty headers and the m3 headers? how much can you get them for and does wayney or what ever his username was, still make them? are the m3 headers a straight swap? thanks Quote Share this post Link to post Share on other sites
thorburn 121 Report post Posted April 15, 2014 wayney gets them made in china. Physically they are very different. Google search and you'll seeSeems the m3 headers usually go for nearly $900 I've got a set sitting on my engine and they come very close in some spots. There are a few people that run them without problems. I might've just got some tweaked ones Quote Share this post Link to post Share on other sites
Arron 227 Report post Posted April 15, 2014 We have just done a m3 engine conversion in our race car.. The only thing we had to change to the the manifolds to fit was change where the mounting flanges were on the mid section of the exhaust Quote Share this post Link to post Share on other sites
