Hey all, was hoping you guys could help me out with this one. I'm looking at purchasing a pair high flows cats, i have a 2003 nm35 stagea and pretty much all the parts im looking at, at the moment are for the infinity g35 and nissan 350z, im currently hooked on purchasing one from z1 motorsports and purching thier z1 highflow cats for the g35 de model, now all i need too know is if the catalytic converters are the same on the g35 and my stagea. if so i know it will fit, ive already looked a ton and from what i can see they look identical but just need too make sure before i go through with purchasing something from overseas which is pricey. i couldnt manage too find anything local as of yet hence why purchasing online and was going too get it custom done but the guy didnt look too keen on doing it and quoted me far more then i could afford soo only got everything from the mid pipe back done. but if any of you know any high flow cats which are a perfect fitment and/or if the g35 runs the exact same cats as the stagea would be a great help.thanks!
