hi everyone, i signed up here at Sau bcoz every skyline owners in australia comes to this site to discuss anything about skylines, so here is my story, i recently bought my first skyline, its the RB25 dett or otherwise knwn as r34 gtt, now, for some reason, i have been reading magazines like imports car, and they show a list of mods for r34 gtt and how to save but still got the horse power, they basically said to go for local names and it doesnt have to be branded product,so i decided to go really cheap, firstly, i got a really cheap pod filter, i bought it from a local shop around, its worth $100 altogether including the ring that connects the pod filter, pod filter itself was $25, australian brand...dont know if its good but it does the job still..and secondly, cat back exhaust, DRIFT brand, i dont think its loud enough compare to other exhaust but its good for me..now, should i change any of the mods?? is it worthy?? how big is it really the difference if i go with the big names like Apexi pod filter or N1 exhaust??can someone shade some light here please?thanx heaps for ur time..
