ravydavy 0 Posted December 30, 2008 right I've tried searching on here in the search for manifolds and it basically brings everything up apart from what I need. I'm thinking a maniflow manifold for my mi16 but after that I need help lads. Has anyone proven figures with exhausts on the rollers? Which do I buy? I'd like to keep within most trackday limits if poss. Otherwise what's the point. Tried calling DES today but weren't open but to be honest I'm glad cause I want your advice first before I buy. Your help in advance is much appreciated. Best regards and a happy new year David Share this post Link to post Share on other sites
Saveit 0 Posted December 30, 2008 If you engine is not highly tuned, then dont bother. The standard manifold is quite decent. You will not gain very much compared to the price of a full racing exhaust system. You could change the exhaust system from the manifold and backwards to 2" or 2.5". This is much more effective at a price/performance point of view. Share this post Link to post Share on other sites
