its the same boresize backbox as std,are std exhausts not restrictive then?
i got told my exhaust was restricting me from makin more,the tuner didnt even know what kind it was,but it was a scorpion,also said about my mates scorpion which again tuner didnt know it was a scorpion,he just said "your exhaust is restricting the power,what kinds it?".its only common sense that the same bore as std is gonna restrict it no matter if its s/s or not
