hey guys, got 2.5'' stainless steel xforce catback fitted last week. Been driving for a few days now and what i have noticed are the following:
1. Fuel consumption has improved from 11.3L/100KM ish to 10.5L/100KM. My driving manner hasnt really changed.
2. Cold start is quite loud for about 10 seconds, and fairly subtle on idling and cruising with foot off the accelerator pedal. But once you put your foot down say from 1500rpm, it will stay at a nice deep tone all the way through the rpms.
I have uploaded a couple photos below. Havent had a chance to video record drive away sound yet, but at low revs it sounds similar to this video here:
