yeah im aware of that, i want driveability and torque not massive dyno numbers

and honestly, the car felt better after i had a press bent catback, and got heaps better after the extractors and cat were changed, maybe i was just imagining but it felt freer (i have a dc2 not a dc2r btw so my system was probly more restrictive)

also it depends how badly the system is bent..

additionally, do resonators (not spelt resignator by the way) make much difference to performance, i thought they only changed the note and weren't very restrictive?
