With only the cat and muffler deleted, is there any benefit of a 4 inch dump pipe? or is this only to suit a full aftermarket system?

I have what would probably be a 13 sec warrrior with edit only (T5) manual tuned by Nizpro and I reckon my car is SO MUCH FUN on the street... excellent 2nd gear slides are awesome... I'd hate to think what a 12sec manual would be like on the street... scary to say the least...

With regards to reliability, I've had NO issues with reliability, none what so ever.

If you want a manual 12... I'd go for the Edit, Injectors and Valve springs, I think you'll get close... gonna cost you about $3.5 from Nizpro, don't know about what other tuning shops cost but that'll get you a fair whack of fun that is for sure!! A user from here DRKXR6 has just on the tip of 300rwkw (299.2rwkw) with this combo with a T56 manual box...

RAPHOON runs this set up... better throttle response is a definate.. maybe he can fill you in on it

I have injectors and cat replacement. ~300rwkw

12.80 @ 116 is my best.

12's aint easy in a manual on propper 'street' tyres....

Good luck with it..

thanks guys
