VTR EW10A exhaust upgrade, gear ratios  Hi everyone, this is my first post here.I'm from Brazil and bought recently a C4 2.0 16V, it's a EW10A equipped car, and it's been a nice car, way more smooth than my older Focus (Mk1).But I have the sensation that the exhaust is rather restricted, and I want to change my exhaust, the whole thing, from manifold to the backbox including decat.Reading here someone said that the manifold from the VTS are better, but I never saw one of those, looking around on ebay for 206 GTi parts, the manifolds that we're available I was looking to buy a VTS OEM one, cause I've had problems with no name parts in the past. where I can find one of the OEMs?I was planning to remove the cats, will the engine management go crazy? There's something that I can do to avoid it?And about the gear ratios, there's any gearbox that have longer ratios? A C5 gearbox or others? I found the 60 mph @ 3000rpm rather annoying... it's a 5 speed gearbox....Thanks! By padula  On Wed Mar 07 2012, 05:28am
