Exhaust setup - Tuning question
 

hello, I have a 2011 370z nismo #278... I was thinking about getting the car tuned this summer with orisis uprev, my goal for the tune is to be a bit more peppier throttle wise and such. Ive had my 350z tuned with similar modifications and it's such a blast to drive... so here is where my question comes in... I have two different exhaust setups;

mods that will not change
stock intake (drop in filters will be added), Kinetix HFC, stock Nismo exhaust with resonator deleted..

first one: quiet/ most normal

stock intake (either K&N or drop in filters will be added), Kinetix HFC, stock Nismo exhaust with resonator deleted and stock muffler

2nd one: damn loud


stock intake (drop in filters will be added), Kinetix HFC, stock Nismo exhaust with resonator deleted and AAM Burn titanium Short tails (fancy way for muffler delete)

Will I be seeing a huge difference with the 2nd setup compared for the first one, or will they be relatively the same??


(with the Canadian dollar in the crapper, I wont be able to pickup any mods until it comes back up)

Please dont reccomend me to buy a new exhaust or anything of the sorts!
any input will be greatly appreciated!!!!!

Difference in volume will be huge, difference in power will be moderate to small for NA mods. HFCs are good but I still think that's the biggest restriction you will have in that setup. Also ECUtek is a bit more up to date with features the, uprev not that uprev is bad, just not as good.
