Nick C 0 Posted June 7, 2006 Has anyone got or used the longman exhaust manifold fopr the 1.6/1.9 8 valve engine? If so is it any good? Cheers Nick Share this post Link to post Share on other sites
smckeown 1 Posted June 7, 2006 i have one going on my track car. I did my research and blackscooby was pushing 170 ish bhp if i recally on standard manifold. It's only serious power do they look necessary. I dont think anyone had some back to back tests to prove thaie effectiveness or when they become necessary Share this post Link to post Share on other sites
