Batfink 201 Posted September 9, 2007 I have two systems off two different cars. One that has been fitted to a standard downpipe, and another that is matched to a magnex manifold but lacks the backbox. I want to mix the bits to make one good system Did they sell different backboxes for each kit as if I put the backbox on the manifold kit it looks like it will be an inch or two shorter Share this post Link to post Share on other sites
Henry Yorke 269 3 Cars Posted September 9, 2007 Yes. The full Magnex system had a wider bore pipe than standard, so they did 2 back boxes; one for the standard system and one for a full Magnex system Share this post Link to post Share on other sites
Batfink 201 Posted September 10, 2007 the bores actually look the same but thats annoying about the backbox Share this post Link to post Share on other sites
