I don't think I want to mess with headers seems like a lot of work...But with those 3 mods I should see some performance, Right?

It would be Ok to do the exhaust next. But, the tuner will show you more of what it can do with the heavy H2. You should see performance with these mods but, do not get expectations to high and wait and see what happens be surprised. Leaving the headers out will hurt the overall picture but hopefully not to much.

I went with intake, tuner, and headers with catback exhaust out the back. The tuner should show You more response on the H2 because it is so heavy, It will increase HP but, more importantly the tuner will increase torque which is what you need to pull boats and just get the ride to take off quicker.

Changing headers You raise front end a little so you can take front wheels off. Jackstands please! You will need to remove the rock guards on bottom. Remove the inner fender liner which have those snap out and in buttons. You will have an open view of exhaust manifolds. Remove spark plugs so you do not break them. Unbolt the manifolds and install the headers. We had 2 guys one on each side and they did the header, catback system, and custom exhaust bullt in 3 hours. They installed all that along with a 160 degree thermostat.
