Jacko 2153 Report post Posted October 20, 2010 (edited) I wonder if they fit an E30 (m50'd), the way the last 3 primaries are bent makes me wonder. Any chance of a profile shot with a ruler? Edited October 20, 2010 by Jacko Quote Share this post Link to post Share on other sites

Tristan 338 Report post Posted October 20, 2010 Sorry to be noob but what difference would result from these over the OEM ones in it now Quote Share this post Link to post Share on other sites
smiddy 76 Report post Posted October 20, 2010 Would be kind Tristan to call the OEM manifold average. Not sure on 530 spec but have seen them with under hood manifold cat combos. To fit these if you have cats on manifolds would require sensor relocation, cat relacement. Around 12hp gain and mid range torque over stock. Quote Share this post Link to post Share on other sites
