I'm running Mines stainless dump pipes, then spilt titanium front pipes that come into 3.5", then a japanese racing cat, and 3.5" stainless custom welded cat-back by a japanese performance garage straight all the way. I'm just doing 1bar fer daily driving. Any idea how much psi of boost the 34 GTR n1 turbos can take safely?
I've also got Tomei 260 poncams IN & EX with i think 9.15mm lift, Tomei camgears n etc, with denso 550cc injectors & Greddy fuel rail, sard fuel regulator, bosch 044 fuel pump running my fueling. Car was tuned before in japan, now i'm linking up with BD4s fer a possible tune up next time as yeah like u said, finding a good Fcon tuner in Brissy is almost impossible.
