OK, so im researching this as I will want one soon(ish) and im not paying upwards of $1000.

According to some websites, shops and people's opinions, the TFSI and TSI downpipes are not interchangeable.

However, listings on ebay and other online shops have the same part for the TSI and TFSI downpipe. Mk5 and Mk6 are listed with the same part. There is a turbo flange available that can be used on the TFSI and TSI motors.

On BriSkoda, a member there installed an S3 downpipe successfully on his FL-vRS with the TSI motor.

A3, S3 and TT use the same downpipe.

So, this would mean that my FL-vRS would probably be able to take anything compatible with virtually any TSI or TFSI engine.

Someone please explain if I'm missing something, but to me it doesn't add up.

Can get these parts for significantly less prices in the US.
