Baz 421 Posted April 26, 2006 Seen and heard about these a couple of times now, are they any good? Always hear how the standard system with split downpipe that serves as a 2>1 is good as is, anyone got one or has compared them to others? Think they're a piper or mongoose item?

mbayley77 0 Posted April 26, 2006 just thinking about this and the gti-6 manifold if used with a standard downpipe from 205 goes from 4-1-2-1 Now im no expert but i dont see any advantage in that at all. Sorry no help at all on that post was there! Share this post Link to post Share on other sites
