Re: Spider downpipe interchange

["Dean W. Cains" <dwc@xxxxxx>]

Hi PJ:

If you've got manifolds and downpipes from any Alfetta variant, I'm afraid 
you're not going to get those on a Spider.  The shape of the manifolds is 
just too wrong, as the Spider's manifolds angle more towards the rear, and 
the Alfetta's are more vertically-oriented.  For my '87 Spider I've got a 
pair of manifolds from a '72 - '74 Spider, and have the stock '72 - '74 
components all the way to the back of the car.  There is of course, no 
catalyst, but I have added a fitting for the oxygen sensor.  You could do 
the same for your '81, but wouldn't need the fitting for the sensor.  If 
you need to use a catalyst, you'll have to do some custom welding, but 
nothing beyond the scope of a good exhaust shop.

Regards,

Dean
