Stock HP

Stock HP
I have a 2002 T/A and a few questions. First what is the stock hp on a 2002? Second will Bassani headers and Y-pipe work with slp loudmouth 2 exhaust? Third I have heard a few times on here people say they have gutted cats, what exactly is that? A guy at my local shop also asked me when I was getting my exhaust installed if I wanted the cat on or off. What exactly was he referring to? I told him to keep it on.

First, don't worry about the horsepower rating on the 2002 Trans Am. It's all BS anyways. The factory underrated these cars badly, so not to step on the 'Vette's toes. Most 2001-2002 will dyno at the rear wheel around 320-330 horse. Next, don't waste your money on the Bassani headers. They are only mid-length which don't add much to the power output compared to the factory manifolds. If you're going to get headers, get a set of full length. Kooks are the best, with QTP a close second. Both are very good for freeing up horsepower, they are both constructed in stainless steel and fit very good. The Kooks y-pipe has a much better fit reputation compared to QTP's.
If you're looking to increase the power in your car, look first at a decent catback. That's easy and relatively cheap. Next, get a good air lid. SLP has a good one, MTI also. If you can swing a set of headers, get them. Next, would be a cam and/or ported heads.
Lastly, most of your questions have been answered hundreds of times before. Trying using the search function. It is very good at finding what you need. Plenty of research will allow you to customize your car to your personal tastes. Just remember, it's your car so don't let people tell you what you "need" for your car. Enjoy it and have fun in the process.

Oh, and gutted cats refer to the catalytic converters being hollowed out. They are filled with a honeycomb material designed to "cleanse" the exhaust of harmful exhaust byproducts. You'll see a lot of people recommend removing their cats for more power. While there might be some gain, it's also illegal to remove them on a street driven car. If you're caught, it's a ticket. Also, the shop that removes them could be fined by the feds (EPA) for removing them.
I'd leave them on. You're not losing any power you'll notice.

300-310 maybe, but not 320-330. A stock F-body putting down 320 or more HP to the rear wheels is rare. You generally need some bolt-ons to see those kind of numbers.

I put down 323 with a lid only, 2000 TA, no LS6 intake. 320-330 is very likely in an M6 01-02 ls1 due to the LS6 intake.

Pacesetter are the cheapest good ones. They're rust a bit over the next few years, only run about $400. Kooks and QTP are equally good and stainless, they won't rust- but they'll run you about $800. Unless you plan to own the car for 5+ years I'd suggest pacesetters.
But lid is much cheaper ($100) and you will gain about 10hp from it, I say take care of the cheapest stuff first then move on to full exhaust, and then whatever else you want. It doesn't make sense to me to invest $1,000 or more in exhaust before doing something as simple as a lid.

Now, the 2001-2002's have CONSISTENTLY put down more power than the 1998-2000's.
But, really, who gives a **** what it lays down stock. I've modded my old 2000 and now I have a MTI Stealth 2 cam and new LS6 heads to install on my 2001 WS6 (the 2000 was stolen last year).
The original poster is going to mod also, so stock numbers are really pointless unless you really care about how much you gained. But, then, why would you. All anyone really wants is the final number to be a good number; not how much one gained. I don't hear people bragging that they picked up x-number more horse over stock. It's all about the total you have right now and how to increase it.

If you have a problem with the industry standard then you have other issues.
