badboygolfvr6 0 Posted February 18, 2008 Report Share Posted February 18, 2008 hi. i was told by somebody it makes a difference performance wise..if you fit a exhaust system first and then an performance air filter after. is this true? does it matter which modification you fit first?

ingham 5 Posted February 18, 2008 Report Share Posted February 18, 2008 imo the air filter makes most difference Link to post Share on other sites
craggsy 91 Posted February 18, 2008 Report Share Posted February 18, 2008 Kinda difficult that as if you sort air filter first it means engine is getting cold air quiker and better but cant expell hot gasses as quick. And vice versa Link to post Share on other sites
