1. According to some people, a 1992- VW Jetta GLI has a dual exhaust manifold, and it uses a 55 mm cat. I have a 1992 VW Jetta CARAT, and it has the dif. engine than the GL's, has more hp, and torque. My question is, if they both have the same manifolds, and they take the same replacement cats, from TT, can I use a GLI exhaust on my Jetta Carat. Or are there some other diffrences.
If the cats are the same size, then it will fit fine. The underside of all jettas are the same (well except for the syncros)
hey, are you sure your Carat doesn't have a dual downpipe? Take a look, it just might...
BTW, the 8v dual downpipe is different and incompatible with the 16v dual downpipe.
Thats wrong. All the dual downpipes are the same, whats different between the 16v and the 8v on the exhaust side is the bolt pattern on the exhaust manifold to the head. So a 16v exhaust manifold wont for on an 8v, but a 16v dual downpipe will work with an 8v dual exhaust manifold.
was reading the 16v forums here are a few
16v intake manifold sizes
16v head on an 8v block
differences between 1.8 and 2.0 heads
Intake sizes: 40mm (1.8l 16v ), 42mm (2.0l 16v ), 50mm
16v head on an 8v block wont work without different pistons and maybe some other stuff
Differences between 16v 1.8 and 16v 2.0 heads: click here (careful its a big pic)
If I'm wrong with any of this, lemme know [IMG]http://*****************.com/smile/emthup.gif[/IMG]
