Hey guys,
I just got my hands on a 2003 SVT Cobra with 13,800 miles from my Uncle, and am lookin to get a little bit more power off of this incredible motor. I know the car already has a new S/C pulley (pushing 10 lbs now), an "intake" (i dont know if tis a new MAF, but i know is got the K&N, but im [pretty sure its only the K&N], and he has some sort of performance chip, but I havent tried to even mess with that yet. He said tis probably pushin about 450 hp now, and no idea of torque.
Anyways, he has told me (since I havent paid it all off yet) that I am not to touch the car, and to leave it alone because its fast enough. Yeah right! Who is he kidding? This commin from the guy who has the 04 mytichrome cobra with 650+ hp lol.
But yeah, he did say I could put on a Cat-Back system. So, I am asking what cat-backs sound the best, and which ones give the best power increase numbers. Also, are there any other things I could swap off, un-noticed, to get more power, like say the throttle body, MAF, or something?
If I change the MAF, would the K&N still fit?
What kind of prices are we talkin here?
Let me know people, thanks a million
This guy looks so cool

some site i read said that any more then 10-15% change in the SC will not be good w/o reprogramming the chip. so i guess, if i get a 2.76, exhaust, belt, and get it retuned, ill get huge gains.
how many lbs of boost does a 2.76 push?
should i get headers, xpipe, and exhaust, or just exhaust, or just xpipe and exhaust?
obviously, i would want to do this all at once, not at different times, so the exhaust is programmed as well
any specific company / website you recommend for a new pulley?
what about that accufab throttle body? is it worth it, based on what i have? based on what i will have?

look at my sig.. do that.. and u will get the hp u see.. maybe more.. if u have 93 octane.. im doing all this on 91octane
Pulley. billetflow 2.76
Exhast: Magnaflow or bassani same thing
Throttle body: Accufab
Ported Blowr: Apten only!!! nothng else.. u will lose power no copys
Chip: Diablo sport nothing else..

this is great info also just picked up a 03' SVT cobra, no mods it only has 3,854 miles. what shold i do to get more power not looking for high hp but enough to have fun. i've worked with turbos but not SC, any info would be good.
i flipped the switch for the chip, and noticed that when it is down, and i go WOT, the boost gauge goes past 10. lol. now, that makes me think it it is rather nice pulley, a much smaller one then i had thought. How can i check what the pulley size is? The stock cover is still covering it, so i'm assuming I will need to be told how to get that off too. Do i measure the radius, diameter, or circumference that I am supposed to measure? That measurement is in inches right? Anyways, I am still looking for opinions on what to do for exhaust. My Uncle's Cobra has headers, High Flow H-Pipe, and I dunno what kind of a catback. That car is just too loud. I mean, of course we all assume nothing is really TOO loud, but when u need to sneak into ur neighborhood late, or do for a long drive with your lady, loo loud is too annoying and hard to deal with ... and hard to hear. So I was thinking either just a catback, or catback and hi-flow x-pipe. After my old 94 5.0, that no cat thing is just too loud, and annoying when it comes time to do emmissions :-\. But yeah, this Cobra is begging for exhaust. I can hear the power in that motor needing to be let out lol.
Anyone know where I can get a nice gauge pillar for my car so I can install a new boost gauge, and my Air Fuel Ratio gauge?

k well its not just when the switch is flipped, the car boosts a good 11-12 psi, at least, so thats cool. any idea as to how nog the pulley is. it looks like the diameter is about 4 inches across, and i now that it cant be a 4" pulley, there is no way. Am i doin somethin wrong, or is this right? I am guessin the size of the pulley, its hard to really tell behind that pulley cover, but it seems pretty close, about 4".
Anyone have any ideas at all about any of this?

combatstang ive got a fully stock 03 cobra with less that 5000 mi and was thinking of swaping for headers and to either magnaflow or bassani catback you said you blew your motor because you didnt increase the boost what should i do?
03 Cobra Cheap Power Mods?
