i know it depends on future plans for the engine but lets just say im all motor for now.... it needs to correspond with my 96 ls greddy evo with a test pipe( straight piped ) whats better 4- 1 or 4-2-1 and which brand ... thanks for the imput and for u **** people yes i checked the search

 

sorry .. i do have lots more mods but whats important is that it needs to hook up with my exhaust greddy evo cat back with a test pipe thats all 2.25 piping i believe or is it 2.5 ?? .. thanks
