So, it seems ill never find a 4-1 header lol.. so the other day i stripped the tin from my 2.0 (non SS (IMG:style_emoticons/default/smile.gif) ) heat exchangers and inside was one pipe per side?
I have two small "stub pipes" that go into the case, theyre about a foot long and have a flange on the eng. This is where the exchanger connects to, but is it correct there is only going to be one pipe per side?? just doesn't seem right... saw this ad on samba and now im really confused: http://www.thesamba.com/vw/classifieds/detail.php?id=539584 he says he stripped 2.0L HE's, but his has 2 pipes per side... what's wrong here... EDIT: here's a pic of what's on my engine. one side is removed (stripped a stud so i left the other alone (IMG:style_emoticons/default/wink.gif))  |

from day one, up until 75/76 there are two pipes per side, encased in stainless that come off the motor and head towards the rear of the car.
To meet EPA requirements of the 75/76 model years the factory added a CAT. To fit the cat under the car, they turned the heat exchangers to face forward and run a loop back towards the rear (and added a CAT in the extra real estate). Your system is also more restrictive due to it being one pipe versus two..that also aided in lower emmissions...less flow, lower power etc. Rich |
