Definitely. That and cold air induction would be the first two things I would do to a stocker.

About 10hp at the rear wheels give or take a few hp, it depends on the brand of cat-back. Its usually the first step in modding an LT1. That and a CAI.

Ok good. Now let me ask this. Would low end torque be hurt by getting a 3" c/b and doing the cai kit. I hear that it may or may not and that it may make the SES light to come on because of the lack of backpressure.

Those are myths. You don't loose any torque by installing a cat-back. Infact you gain torque. And your check-engine light won't come on becasue there is no "back-pressure sensor" on your car.
It won't affect emmisions either, just make the car a little louder.

It won't hurt low end--it will probably improve it. Never heard of making the SES light come on because of this mod.

People sometimes have ses problem after header install. Not aware of any with catback or high flow muffler.

Check out jegs or thunderracing. Both of those have good prices.

After I put headers on my thirdgen I had an SES light every once in a while. On the current car I haven't had this problem. I think the PCM in these newer ones can compensate a lot better for mods

Mods are in the sig, I haven't tripped an SES light ever(unless my dumbass forgot to plug in a harness!!)

A buddy of mine with the 30th ann Z got his Moroso for $160 from a local auto parts store (McCullough) that specializes in performance parts. He went in, told them Summit sells them for $180 at the time, and they ended up cutting off $20 from Summit's price. He doesn't know anyone there to get a hookup either.

Another buddy owns a 00 GT and went to the same place for cold air for his Stang, and they told him they don't generally sell parts for Ford vehicles .
