I have done many searches to this question, but all of the answers are old. we Now know that KA24DE's do not require back pressure.

KA24DE entirely stock as of now. Plan to build engine for turbo in 2 years but for now she will be N/A and daily driven. I am leaning toward 2.5 for quiet ride.

I was told megan racing drift spec 2.5" because with the included silencer, it sounds stock but without it, it makes it sound sweet and obviously give more power.

I heard that 2.5" gives more low end torque. That's what I like... torque.

Should I go ahead and order that kit?
