Altima Coupe Headers Altima 2.5 Vs 3.5 Race?

Altima 2.5 vs 3.5 race? - altima coupe headers

I have a 2.5 6-speed manual Nissan Altima Coupe 2009 with cold air intake and exhaust manifolds
would be faster than my friends 2002 Nissan Altima 3.5 auto?

Zero percent of my stock car is 7.4 seconds. I guess the mods around shave 0.3 to 0.6 seconds in this figure.

Zero to sixty Test 2002 3,5 7.2 seconds is, but it was a completely new car with a 5-speed, because the car is 7 years old, and automatically assumed it was probably about 8 seconds. flat.

Opinions?
