Milltek choices?

tku said:

Hi guys, first of all im sorry for posting a newbie thread but was thinking about having a milltek exhaust done and need to know the following details. What is the difference and functions between getting a downpipe and hi-cat exhaust or just a normal non-res cat back?

If you read around the forum, you will find a lot of literature on this.

1) you want the turbo back exhaust.
2) if not enough €, go for downpipe and hi-flow cat: these parts affect the gas flow & backpressure right from the turbo, and have the greatest impact.
3) buy the full system, resonated is loud enough, I have it. Please do not go for a de-kat pipe, the environment and I will thank you.
Cheers,
AJ
