Horsepower and Torque Gain
Hi, I was just wondering how much horsepower and torque gain I would get if I got LT headers and H pipe with no CATs and catbacks on my 03 GT. But I would have to keep everything I took off and reinstall it in 07 for my E-Check. So would it be worth it for the horsepower and torque gain.

that should help you out quite a bit, but why dont you try and balance out the inhaling (intake) with the exhale(exhaust) your engine is going to be working really hard to suck in air but then not working at all to push it out. as far as inspections go, you should be able to go to a rural area outside the city, bc alot of those places do not require emmisions testing, just safety

O.K Tell me what I should do first, I want more power, but I don't want that rotten eye smell anymore when I punch it. And for going to a rural area outside the city here you need an address to use for your plates.

Your exhaust is far more restriction than your stock intake setup, so the correct place to start would be your exhaust.
Do a full exhaust if you can, if emissions & your budget allow to do so.
You can do a long tube header setup (best hp/tq gains) but they are pricey and expensive to install, typically anywhere from $350-800 for the install. Requires unbolting the motor, jacking it up and in some cases dropping the k-member. They also require a shorter mid-pipe than stock, they are also rather pricey and a catted short mid-pipe is way overpriced. But again, you'll see the best gains with this setup over a midlength or a shorty setup, but all setups are much better than stock, whichever fits your budget...

theoretically you would want to finish the exhaust first so the engine would have an easy time "exhaling" the air it already gets, but if you get a new intake system first, then the stock exhaust is trying to "exhale" more air that the intake gets so its working even harder.
all in all it realy doesnt matter which order you do these in, especialy if you are planning to get both anyways.
just my $0.02

i believe slp makes a mid pipe with removable cats that can be replaced with pre cut and bent steel tubing that just bolt on and off, so thats an idea for your emmisions. i think its only in X though

RE: Horsepower and Torque Gain
yeah i would do a catback swap first like nanaki said.. but its really hard to say about the midpipe because of you wanting long tube headers.. so your stuck with that crappy stock midpipe no matter what until you get the rest installed.. i was going to say just get the catback and get it in then get a demolet intake and a plenum and tb.. either way you go its alot of money so its just up to you..
