Exauhst effect on driveability
 

So i dont know if it has already been mentioned on here but ill put it out there. I have a 2014 base model 370z coming from an 03 350z fully built both manual. Started completely stock with the 370 and immediately the throttle lag from 350 to 370 was apparent. Making downshifting especially difficult to master for those of us with out SRM. BUT....after installing my AAM short tail exauhst and more importantly my STILLEN HFC the throttle response is 8473626383626 times better my god. Which in turn makes downshifting a breeze because of that throttle response. So anyone out there having trouble downshifting this beast...install HFC and thank me later.!!!

Test pipes, exhaust, intake, tune.
Worked wonders for me! :)

Now the only effect it has on drivability is how much noise I want the car to let out lol

If I ignored SRM on my car, my issue with downshifting would be that the pedal placement seems a bit...tight. Could be that I just never practiced with it enough.
