Make sure you change you motor mount in the process...it's a must do when changing your headers. I'm in the process now and it's a pain the *** with the headers on.

@AmDWs6 can you pm me some pics when you do the install? How hard is it to change out the motor mount? Change it with poly bushings? Does it really make a lot of difference?
The car is back home in VA
I'll hopefully be there soon
Can those stainless steel texas speed headers be welded up to the stainless ory pipe? I heard that stainless can't be welded, is that true?

Stock Y is complete garbage and will not fit the LT's without extensive modifications.
You have 2 options.
1) get a TSP offroad y, delete the cats and tune the rear 02's out.
2) get a catted y, retain cats and then you may still have to tune out the rear 02's (some people still report getting codes thrown, some don't).
FYI-you don't have to get a tune immed. as the codes thrown will not affect performance. You will just have the annoying idiot light on.

so the o2s throwing the code won't affect my mileage? lol I'm on a budget, I can only get one mod at a time and I guess I'm gonna get my headers and ory and get them welded and then get the rear o2s deleted and a tune
how much hp do you think I'll be pushing to the wheels with only the exhaust mods and an slp lid and k&n filter + tune and plugs?

Mileage will be affected slightly as the car will run a bit rich and you will want to hear the new sounds coming from your car...haha
LT Headers are usually (give or take) good for 15rwhp or so. You will not be disappointed. Headers will be optimized by a tune though.
What catback do you have?
To be honest rwhp ratings have so many variables involved that I wouldn't want to get started on a guessing game. Don't worry about the numbers as much as feeling the gains you do make and enjoying the car.
I do highly recommend that you research and educate yourself before getting into big mods without knowing what your realistic goal is going to be in the long run. Too many people (myself included) end up buying parts to only have to upgrade again later.
Let me know if you have any other questions, I would be glad to help.

This will absolutely not work, you need an aftermarket Y-pipe in order to fit headers. Easiest way to do it would be to just bolt the O/R Y up to the headers, then tune out the rear 02's because at that point you would be pretty much done with the process all together.

Well if you weld it for one you cant take it back off with out hacking it off. Second when they weld it it actually makes both ends that get welded smaller thus adding a small restiction in your exhaust.

Have Vbands welded onto the headers if you want a clean and easily removable option.
I just installed my 1 7/8" TSPs last week, and I couldn't be any happier. Very easy to install. I think the motor mounts were the hardest part lol.

Just do a quick search on VBands. They will come up. If your buying a Ypipe tho I wouldn't worry about it tho. I had a custom ypipe made so it made sense to add VBands.
Not sure if there is a sticky on doing motor mounts. Once you have the exhaust out of the car they are pretty straightforward on how to replace them.
Subframe connectors have a shop weld in for you.
