I may very likely replace my brand new (cheap) Bosal. It "feels" like it's restricting flow.... Question, on my '84, the O2 sensor is on the exhaust manifold, of course, and there is a plug on the Bosal cat for a later model O2 sensor get-up. I have the cat hooked up so that the plug is on the manifold side (not the muffler side) of things. Is this correct? Does it even matter what direction a cat is hooked up? Newbies want to know...thanks Skip Sent from my iPad On Jun 30, 2012, at 12:45 PM, Jeff <vw.doka@GMAIL.COM> wrote: > Actually, the cat from Van Café is quite a bit better than the Emico brand. > I've used both many times, and that one has more material, is better made, > and performs better in the CA emissions test. > > Cheers, > > Jeff > > > -----Original Message----- > From: Vanagon Mailing List [mailto:vanagon@gerry.vanagon.com] On Behalf Of > Dennis Haynes > Sent: Friday, June 29, 2012 5:15 PM > To: vanagon@GERRY.VANAGON.COM > Subject: Re: EPA and Vanagon Emissions-reducing Vanagon pollution. > > The Emico brand cats are probably the better aftermarket options.
