I've had an RM01A and a Spoon catback. RM01A consistantly made more power than the Spoon.
Im wondering with the Spoon B-pipe on the car, if I change the Spoon N1 backbox to OEM one ,would I get less gains ?
ye Im told that before, I mean if I still leave the Spoon B-pipe on the car, do I have less gains by changing N1 box to OEM box?Where as the OEM BB is rather good up to 300bhp the N1 will still be more free flowing, so in theory be better.

cheers mate, I also fancy the Fujitsobo one as you had, keeping an eye on a 2nd hand one.Well yes. If you remove the free'er flowing N1 and replace it with the more restrictive OEM BB you're more likely to lose power than gain any.
