Any info would be much appreciated.... I have a 90 300zx TT. Looking to do exhaust next. I tried and to my sad learning they no longer make greddy ti-c exhaust systems or mufflers which really sucks. So what do you guys recommend? Ive seen many HKS, which are cool im just not a huge fan of the quietness or the melon launcher look but dig the the dual cannons. any thoughts? also eventually downpipes will be done but a little more research has to be done on that... Could i do test pipes without doing downpipes right away? Would there be a noticeable power difference with or without test pipes? Lastly what you recommend in exhaust size all the way through? 2.5in or 3in?
