Is this all I need for headers?

Came across this nice cheap set of headers on ws6store.com with free shipping to boot.
I only want long tubes on my car, dunno why people ever decided to get shortys or mid length.
http://www.ws6project.com/user_stor/...ystem-chrome-/
Is everything included in that? Says it has the harness, installation tools, headers, CONNECTING offroad y-pipe.
Am I missing anything?
Current mods to the car - SLP loudmouth 1 SLP lid, Ported and polished throttle body.
What's a local shop charge to install these usually? Also, you think I will need a tune after it's installed?
Also, what's the estimated horsepower gain from adding headers with my current setup? Think it will be too loud or raspy with longtubes?

Or, would it be quieter if I just got a hi-flow catted y-pipe instead? Looks like those are harder to come by.
Well what I did was replaced the LM1 with a Magnaflow 14419 (same dimentions as the LM1) then added a Flomaster merge to my Pacesetter ORY. Sounds MUCH better now lol!! Oh... and yes it really is that loud lol

do you have a sound clip of your car when it was just headers?

It's a really small idle and rev clip, but hopefully it will help a bit.

I demand a video of the new setup! lolThis is with LTs, ORY, and LM1...it's screaming loud lol..i blew my ears out in this video

And this is the current setup

I'd look at the Speed Engineering LT's. The BBK is nice, but their y-pipe is only 2.5" vs. Speed Engineering 3". Further, Speed Engineering are stainless.
I'd also suggest polyurethane motor mounts and new plugs while you're in there; also new wires if they've got some miles or look rough. While a tune is not "required," it'd certainly help make the most of the new exhaust. It will also remove codes for no converters, AIR, and EGR (if you're a 98-00).

What's the advantage of polyurethane mounts? I heard some people say it makes the car ride too rough. I'm about to get the plugs and wires done, my car is overdue for that.
I've done about 3 header installs on these cars and BBK were by far the easiest to install. The hardest part of it is getting the old exhaust out. I'd spend a little more and at least get the ceramic coated ones.
I'd also pick up some GM MLS gaskets and o2 extensions, both of which are available on Ws6store.

What kinds of gains are you looking at for a 2.5 vs a 3? Wouldn't a larger y-pipe decrease low end torque? Stainless steel is nice though.

As for poly mounts, the factory rubber mounts sag and compress over time. This is generally the cause of any banging or rubbing of header primary tubes. Replacing the mounts ensures nothing is slopping around. Further, I noticed absolutely zero drivetrain vibration after adding poly mounts.

02 extensions are for the codes, right? I'll be getting those for sure.

BTW, go with the poly motor mounts, they're worth the effort to install a set.
The o2 extensions are for the front o2's. The bunghole for the o2 is obviously a lot further back with longtubes.
You'll have to get the rear o2's deleted though. I think it costs $50-75 or so depending on where you go.
Keep in mind that the 2.5" pipes are NOT the first restriction, the 3" y-pipe exit and 3" cat-back exhaust is. So unless you going to use a larger y-pipe exit and a similarly sized cat-back with the 3" Y-pipe inlets you're still stuck with the same single 3" cat-back which is the first restriction. What that means is the 3" pipe vs. 2.5" pipe benefit is still minimal until the bottle neck is eliminated.
I'm thinking, however, that for the cost between BBK and Speed Engineering, it makes sense to just go with the latter.
