Best mods for under $1500.00

[VegasPackerFan]

I am looking to do some mods to my 03 Cobra:burnout: . Right now I have a MAC CAI and that is it. I want to start up gradeing my ride. I use this car for my everyday driver. Any thoughts on what can give me my best bang for my $$$$.

Any suggestions would be great. Thanks in Advance.

I would swap out the exhaust first because the intake and exhaust will more than likely NOT void your warranty. Then, if you fancy a little more, go with a chip and pulley swap...those 4 upgrades will get you 450-470rwhp...then there's a ton more after that...most cat-backs will run you around $500 unless you like the Bassani, which I have and love, they'll run about $750

Exhaust, exhaust, exhaust!!!!!

Dont forget the X-pipe also....

[InfamousSVT]

For starters go for the exhaust! Replacing the exhaust system alone on these 03/04 Cobra's can get you 25+hp, plus when you get the Headers even more!!
Next a 2.80 pulley and custom tune if you can afford it!:thumbsup:

Good luck with your power cravings!

Thanks. I am looking at the exhaust rout. I want a DEEEEEP rumble. I have seen the video on here with the black cobra. I believe the "H" pipe gave the Deep sound.

For exhaust are you guys talking Cat backs and an H or X pipe??? And do the cats stay on with the H or X pipe??? Vegas is tough on emissions.

Also what programmer or custom tune is the best I.Y.O. One more thing, are after market shifters that much smoother?

Thanks in advance

you have an option for CATS with the H or X pipe...if you cannot get passed (ie a buddy who does inspections)then you'll wanna get the one's with CATS...the H pipe will give you a more throaty sound also...ive got the MGW shifter and its nicer than the stock one

Brand new
MAC 2 1/2" Pro Chamber with HIGH FLOW CATALYTIC CONVERTERS
Fits all 1999-2004 4.6L Mustangs with stock or after market short tube headers!!! High quality pipe is HTS coated, Dura Black coated and includes all hardware.

Would I need a catback system also with this. And does the prochamber take place of the mufflers???? If not what mufflers should I run.

Thanks for the help I am converted Chevy old school headers, 3" exhaust, crossover pipe, suppertrap guy.

A Prochamber is a cross between a X and a H. Go with the just the H for the best sound (IMO). I just ordered mine from www.myfordperformace (http://www.myfordperformace). Talk to Ray Dixon, he got me a MAC H-pipe with Hi-flows cats for $345 delivered to my door!!! No, it does not take the place of the mufflers, I would advise getting a catback as well. I am partial to Bassani but many other systems sound good too. Good luck.

Thanks for the bump for one of our newest members NewFoundPower! I also, will be purchasing my Magnaflow Catback w/magnapacks and 4" rolled tips from him soon!

I have a bassani catless x-pipe and catback, and get a lot of compliments on the sound. It is fairly deep at low RPMS, and at higher RPMS, sounds like a supercar. I am very happy with it. I ran with cats on the pipe too, but I prefer the sound without them.

However, I do not like the increase in exhaust fumes. I may put high flow cats back on soon.

The magic formula for bang for buck is pulley, tune, CAI and full exhaust. I have heard that headers may not be worth the trouble. A Mezierre water pump may pick you up 15 20 hp too. Not tried that yet, but I think I will this Summer.

Not tried that yet, but I think I will this Summer.I just orderd my full exhaust. I went with the SLP X pipe with hi-flo cats(I need to pass emisions) and the Loudmouth catback. The Cat back and X pipe are thier new line of modular cat-back exhaust systems. I went with the loudmouth II mufflers. They say, "similar to original Loud Mouth, but with
a throatier tone and reduced resonance". I guess I will find out. This is going tobe the longet 7-10 days i ahve had in a long time.

Pulley and a custome tune is next.

Pulley and a custome tune is next.Even though you have the Hi-flow cats on it, you will need to have your tuner turn off your back 2 o2 sensors to keep the check engine light from coming on! Since you are getting a pulley and tune, you can just wait until then. I got my headers, catted x, and bassani catback put on and my check engine light is on, but I'm getting the o2 sensors turned off when I get my pulleys and other goodies put on in the next couple weeks!:D

It'll be ok to drive your car without the sensors turned off, it'll run a little rich, but that's ok! It's just a suggestion to wait for the tuner other than getting the MIL's and wasting money!:)

I changed my reply. Just read that you already bought your exhaust. The amer thunder doesn't fit well on the 03 cobras anyway

Parden my ignorance.

But I will I have to do what to correct the O2 sensor fault??? I don't plan on getting the tune for a while. Any suggestions?????

Do I need to get the Mill elim. I was under the impression that the stock O2's would work and not cause the error??? I have a 03

Thanks Vegas

InfamousSVT: Maybe it is because you have the headers. I'm running the bassani X-pipe w/cats and bassani cat back, and my check engine light has never come on. As far as the Bassani goes I love it.

VagasPackerFan: I've heard good things about the SLP system. Congrats on the purchase, the seat of the pants feel will be great. Mine dyno'd at 435 RWHP and 395 TQ with a similar set up.

Thanks for the post and thanks for doing what you do. That way I can enjoy what I do. I have some Marine friends who spent some time in Iraq. Now and back in the gulf war. One is going back. Be safe so you can enjoy your ride.
