Riley 0 Posted July 6, 2008 Ok...A question first about lambda probe position. Ive got a g-werks 4-2-1 manifold...Where do people run the lambda from when using these? I was thinking of not using any of the two positions on there, but instead having a flexi pipe where the cat would normally be and have a lambda nut welded into it. So just after the manifold. This sound ok? As for the sytem, does it sound ok to have: 4-2-1 into flexi with lambda probe, then into center section with just one box (where suitcase silencer would be), then into the rear silencer? Cheers,Neil. :) edit:I know the big exhaust discussion is going on here, but my question is pretty specifi,especially about the lambda position...

flusted 0 Posted July 7, 2008 Mines pretty similar to that, i welded lamda bungs where the cat normally is as i have a front silencer there, then straight through 2.5" to rear box Quote Share this post Link to post Share on other sites
