They say shorties don't improve things much....so I wouldn't get expectations too high on getting much performance gains. Maybe some bottom end torque improvements & a bit better throttle response...maybe.?? Unless your current exhaust system is leaking pretty bad and the cats are plugged up, then getting things resealed and controlled you'll see/feel a difference.

It will be interesting to report back as to what you actually improving on. Even if it is on your butt dyno. Maybe do a 0-60 test before and after?

With what your planning....noise will be increased for sure.

I havnt picked up the headers yet, not expecting anything drastic performance wise, maybe just enough to notice lol. I do want more noise, nothing extreme. But a good rumble under acceleration wouldbe nice

a good tuner will provide more increases than anything, especially after the exhaust work is taken into account.
