What i heard is that catless downpipes should be combined with a engine tune which may explain your problem. Good luck with the hunt for HP & Torque

thank you! well i guess the car needed a few days to run in i guess. hahas had a drag race with my friend's M3 (which i always do whenever i or him do something new to the car) and he said that in 3rd gear, 1M walked over him.

But comparing with another 1M in sg with full akra (downpipes + EVO), at idle my car seems softer... normal? or due to the fact that our downpipes are bigger=less compact/bassy sound?
