Interested in your DP review

You guys who happened to install a set of downpipes no matter if catted or catless do you mind giving me a heads up on these aspects?

1. How was the sound overall affected and

2. Did you notice any difference in the operating oil temperature ?


The tuning potential is given but I 'm only interested at this point in your comment regarding matters above as I have sourced a set of used catless ones at a great price and am standing at a crossroads right now.

Thx

1. catless are significantly louder, deeper noise from the exhaust - really roars when you get above 3500 rpm

2. no

3. improved turbo spool

1. catless are a bit louder, but OK, really nice for my tastes

2. yes! oil temp are lower during hard use

Thank you, gentlemen.

Would some people mind listing who/where they got their DPs from? I'm also in the market to get some catless DPs and I'm not sure which vendor to go with.
