NEW TO ALL THINGS NISSAN
Hi, I have an N Reg '95 NISSAN SKYLINE R33 GTS STRAIGHT 6 AUTOMATIC, it has a 3.7" straight through pipe (no Cat & no Silencer)and exits out a 4" aftermarket back-box...
Its so LOUD !! Ideally I want to buy a nice 5" chrome backbox but also want to be able to pass my MOT etc..
Could you tell me :-
A) Do I need a Cat. Converter
B) How much quieter will my existing setup run if I fitted a cat?
C) Would a Cat still be necessary if I fitted a mid-pipe, or should I use both?
**** Basically I am after a mean rumble but also be able to pass my MOT emissions & noise test etc.. But want it to be the loudest it can legally be at the same time.. ??
Sorry for so many questions but I really want to do it right..
Any light you can shed on this would be uber helpful
Please reply asap
