welshpug 1,657 Posted September 10, 2008 I need a downpipe for a 205 that I'm putting an engine into, it has a 3 piece system fitted. problem being is that my understanding of the systems used on 205's is; early 3 piece system, 45mm ish bore, later 2 piece systems, just over 50mm bore. is it possible to source the later 2" downpipe without the centre box?

Baz 421 Posted September 11, 2008 That's the point of it being a 2 piece system, it's only in 2 pieces rather than 3!! Share this post Link to post Share on other sites
M@tt 77 Posted September 11, 2008 (edited) that said i've got a 2 piece system on my GTI6 205 but when i was reangling the downpipe during the conversion i had to redo it after not getting it quite right the first time and found i needed to rotate the downpipe slightly to stop it hitting my extended quickshift gear lever. I found that despite it being a 2 piece system the downpipe (split downpipe version in my case and it was even bigger than 50mm i'm sure) is actually a seperate section and was actually sleeved and welded onto the rest of the exhaust so i was able to grind off the weld and pull the 2 parts apart which left me with essentially a 3 piece system. i rotated the 2 parts slightly and rewelded the 2 parts together. Now whether the 2 sleeved parts are the same size as a normal 3 piece system is another question. I quite fancy a smaller diameter downpipe as i'm sure my current one is too big and it feels a bit flat and blowy if you know what i mean anyway some food for thought Edited September 11, 2008 by M@tt Share this post Link to post Share on other sites
