So finally had to go home (Lebanon) for christmas and got some time to work on my S3 AMK.
i bought my exhaust manifold from relentless performance in the USA (same company as xspower)
eBay - New & used electronics, cars, apparel, collectibles, sporting goods & more at low prices
and my 3" downpipe decat from them too
Audi VW TT S3 Quattro GTi 3" De Cat Downpipe MK1 1.8T | eBay
Must say the fitment isnt easy but that is not due to the parts but to the location and the tight place.
The downpipe fitted perfectly, the holes bolt in just in place, no drama at all.
The mecanic fitted the exhaust manifold without removing the head, we unbolted the engine braquets holder and tilted it a bit so he had a bit of room to fit the exhaust manifold and bolt the nuts.
I must admit that the quality (pictures will show) of the exhaust manifold is super good. The welding is amazingly made and the material looks pretty good.
The car hasent been properly dynoed yet (since i have a fueling problem) but i can feel the power difference and the sound is crispier
