I recently installed the Fabspeed sportcat and it is a noticeable improvement over the stock DP.
Sounds a hair louder than stock, I barely noticed a difference. Where you will notice a difference is when you let off the gas above 3k rpm and you get the pops and gurgles you don't get with the stock DP.
Improved throttle response.
Car pulls harder all through the range, it is noticed/appreciated more in the mid to upper range.
Smooth. I also have a Jb4 and it really seemed to smooth things out throughout the range. Car pull and runs perfect if your on it or not.
No funky smells.
I had the shifteck catless DP before this and the fabspeed catted feels as good, if not better when combined with the JB4.
