BTW its in your own opinion some people like ark or ssa headers, ark, injen, custom, greddy, ssa are all exhaust i have heard i mean its up to you look in the exhaust thread and listen to some videos and go from there
depends on how much you willing to spend...I say ARK have a N2 and love it..also getting their headers..look around but I looked for about a month and ended up going with ARK..I think they have a sale going on you get the exhaust and headers for 1,500 which is not to bad of a deal <save like 500 bucks> if sale is still going on..they are a sponsor check out their threads!
I have SSA V2 headers, Flow master mufflers with 2.5 inch piping and a SRI INjen intake, it sounds awesome big time just good amount of sound with not a loud crazy sound so its nice and mellow and it gugles down when you shift =)
it really all depends but you have to remember to NOT go straight pipes, ricest thing ever sounding wise, throw in a magnaflow cat maybe even an aftermarket resonator and it should sound very nice
i have an ebay cold air intake with an AEM dryflow with SSA headers and SSA catback. and i love it. although the catback i wish i wouldve gotten something quiter. SSA is too loud and raspy IMO. im putting down NOTICABLY more power now though. idk if i could do it over id have SSA or OBX headers and ebay intake with AEM dryflow and DC sports catback or MUSSA angled tip. if i get the cash ill buy a MUSSA and sell mine. but im pretty happy for now
