If an aftermarket exhaust is used (Bursch) will a pair of exchangers from a 1.7 / 1.8 fit a 2.0? If not what's the difference?

I think you will get a better answer than mine, but I'll start. I think all heat exchangers will bolt to all engines. What must match is muffler to heat exchanger, ie, use a muffler for a 1.8 with 1.8 heat exchangers.

I think they all interchange pretty good, the big difference is the angle of the flange that hooks up to the head. Check the archives.

I have 1.7 SS exchangers and a bursch exhaust and its just grand (and loud)

sorry...1.7 but I am pretty sure it doesn't matter. Here's a similar thread from last week.

Check the PP link to Bursch mufflers. Four different mufflers depending on which heat exchangers you are attaching it to.

The main difference between the 1.7/1.8 HE and the early 2.0L HE is that the 1.7/1.8 pipes bend upwards and the 2.0 HE the pipes do not have the upwards bend. Both will fit on any engine but you need to swap everything as a package (HE, Exhaust Hanger, Muffler). A muffler from a 1.7/1.8 will not fit the 2.0 HE's and vice versa.
