I went for a test drive yesterday evening in -15*C weather.
My god, this car is getting scary! Car is on skinny 205/50R17 winter tires, and I could spin the tires in 4th gear with my Quaife 3.46 LSD!
Great job by Dzenno @ PTF with his quick update to my custom stage 2 agressive tune, and this very affordable N55 downpipe from Mike @ N54tuning! Once the weather gets warm, and Im back on my 255/35R18 ZII's, I will log 3rd gear hard pulls, and send the resuls to Dzenno to make sure that everything is right, and every ounce of performance is squeezed out (all this is free of charge once you buy a custom tune).
The sound produced by my catless downpipe is not that bad and growing on me. can hardly hear anything different in the cabin under normal driving conditions. Under partial/full throttle, a nice exotic sound is produced, and a big howl comes from the turbo and downpipe area, which floods out the exhaust note completely.
I think I will leave the exhaust system as is for now, as the idle sound during cold starts is my only annoyance, and is a minor inconvenience. The exhaust note sounds nice and agressive only when you get on it. What more can I ask for, from my otherwise stock exhaust system!
