Its time to make my 300C go faster.
What are my options?
What gives me more horsepower for my buck and what ill make my car go under 6 seconds in a 0-60.
Also what performance mods are worth it and where i can remove them incase of warranty issues.
All available options please.
Please let me know what I can do.

You mean you are not under 6 seconds, C&D got 5.3 last year. Others have not been so fast when testing the C, 5.6-6.3
Well im not really into racing, but after someone said that they would rip me in a race with a G35MT, i looked up some info on google and it said the 5.7 is 6.3 and the G35 is 5.8 or something, so now i want mine to be faster, but im still not gonna race, I just wanna know that my car will go faster.
Any ideas......
I was thinkin Jet Chip and Intake, but i dont know much about it.

Dynatech Supermaxx headers and magnaflow cat back....throw in CAI for the helluvit and you've got at least a 25RWHP gain and close to 40RWTQ if I'm not mistaken.
Yeah, but that stuff will void my warrany and I wont be able to take it off myself in case I need to, I would have to bring it to a local shop, thats why the jet chip and intake i was lookin into.
Anything else like that that I can do.

No it won't.

The only portion of your warranty it will void is any work you may need to your exhuast.....which is moot because you're going to be replacing it entirely.

If voiding your warranty is your conern, then there's NOTHING you can do that will make any power difference.....but it won't. Your warranty will be fine.

So you telling me headers will not void my warranty?
If that the case, I will be looking into that, plus what if I have an issue with my car and bring it to DCX and they see that, your tellin me they cant void my warranty if i have a problem with my engine.
Ok, so right now im lookin at an intake headers and jet chip, well there goes the 1000 dollar mark, any other ideas.
I dont think im gonna go with an exhaust, but i really want to.
BTW, and ideas on what name brand Jet Chip is good and wha stage.....

NO, it is illegal for the manufacturer to void your warranty unless they can prove the fault was due to the modification. You have to understand SEMA is a huge organization and is also in bed, so to speak, with the manufacturers.

I've said it many times before and I'll say it again, if a service manager/writer refused to cover anything under warranty because of a modification you made it's because they're being DICKS and not because they have a legal right to do so....If you have any problem it's conceivable you would have had a problem with them regardless....It's moot. Headers and exhaust will NOT void your warranty period!

Stay away from mods that do nothing like Jet Chips.

HEADERS ARE THEEEE BEST WAY TO MAKE POWER ON A 300C. Bar none! Go do some research on previous threads and the ridicuously incredible amounts of power they are adding.....Near SRT-8 power to be exact!

Anything else you're wasting your money on.

Since you put it that way, I may just add headers and thats it.
Also about how many more horeses will I get.
Any suggestions on where to get them?

Various Supporting forum vendors carry them.

GSM Motorsports, Tbyrne, Hennessey, etc... They've had "Group buys" in the past and will probably have more in the future.

They're pricey but worth it IMHO. THey come with high flow cats, are very thick steel, and coated for $1295.00

I think i should edit my first post about how much I wanna spend.
I want to keep it below the $1000 mark after all the installation and shipping and crap, maybe thet will be a mod for later on in the future.
So, back to lookin at the intake and the jet chip which is more afordable right now.
Your telling me that it has absoultely no power gain at all vvv?

Yeah, what you say is correct but remember too that they DO have the legal right to refuse to work on a car with ANY modification to OEM componnets. Should they feel the need to VOID a warranty, they would have to substantiate the claim with a little more than just words.

BTW - easiest removable modification for HP/dollar is nitrous.

My best friend works for a major auto manufacturer's legal arbitration group for Lemon law / buy backs and warranty claims. Tread lightly as it is a piece of cake for a service department to submit papers to void your warranty and quite the ordeal to have the marks removed from your VIN. Spend time to get to know your service department's manager or personel. Spending a bit of time up front saves you TEN FOLD later.

Hence the second part of my post as an example that dealerships can be dicks. I doubt they'll submit a form to void your warranty unless you're being a real **** back to them....It's best to find a dealership that's "Mod" friendly.

Just so i know, what do you all think the best Jet Chip Stage 1 is, and also, Im interested in the Airaid intake because it does not replace the tube so it will look stock when I have to goto the dealer, is this a good intake.
I hear they all do pretty much the same crap?

If you're looking to make some power on the cheap, I would go with the set of headers (Forgot who makes them) that have a GB going on at the LX forums.. I think they're around $700 or so..

Next for $100-$150 have the rear resonators taken off and straight piped back to some nice tips.

Under 1K and should make some nice power and sound changes.

BTW, as far as racing a G35MT, it'd be a very close race.. Depending on how good of a driver he is with a manual tranny, you should be able to keep nose to nose at worse, and beat him at best. There wouldn't be any "spanking" of either car though.

Noticable power increase. Hmm...let's see, as I've done each mod in stages - exhaust, Volant, and then Jet stage 2. So I'll give my .02.

Exhaust and intake will make the car sound great - like it actually has a hemi. Throttle response will be increased slightly. These are "sound mods" IMO, and if they add more than 10rwhp, I'd be surprised. Love the sound, so I recommend these if that's what your looking for (personally, I want my ride to sound as good as it looks, so these are important to me).
*on edit, I'd buy the Mopar intake if I did it again.

Jet chip - car idles a little smoother, but no power gains noticed, it does maybe hold gear changes to a slightly higher rpm, but not noticable enough to put it on my "must buy" list. Save your $$

Headers - Next on the list and from my research are showing good gains. I would go Dynamaxx Long tubes, rather than shorties that keep the stock cats.

Gears - they don't make any... yet...let's hope to see some soon.

Programmer's - not yet but maybe after SEMA? If a good one comes out, get one asap, especially if they program in transmission/torque control functions.

Now for my real advice: :)
Run down to the local dealer asap and trade in the C for an SRT8.
It will shut the guy in the G35 up in a hurry.

CAI and exhaust will help

I did a 5.41 bone stock hooked up to a machine (which unfortunately had no printouts) a few months ago.

MOPAR CAI increased throttle response and performance, although there is no dyno on HP gains.

I am next doing a Magnaflow exhaust system which is dynoed at anywhere from 11 to 22 hp gain depending upon where in the rpm range you are.

That ought to keep it down in the lower to mid 5's

O BOY,
how i would love to do that, but i would not be able to make the monthly payments if i got the SRT8.
Unless i trade in my C and get the SRT8 and make the same monthly payments, then I would, but hows the gas.
Ive read on this forum about the JetChip and only heard good things and better response, now after i hear your response, it gives me second thoughts.

Yes, I agree with everything 5point7 said....especially the SRT-8. :D

However, my opinion stands, if you want to spend MAX $1,000 then save your money for some long tube headers and do the resonator delete (near free really, maybe $50 at most)

THAT and ONLY that will give you the power you need. EVERYTHING else is just a waste of money.

For instance, lets say you spend $1,000 on jet chip, CAI, even cat back system to give 10RWHP.....Wouldn't it be worth it to forget all that crap, spend a few extra hundred and get ~30RWHP???? Not to mention the HUGE increase in torque.

GET THE HEADERS!

Other than that, save your money.

P.S. As for the GB mentioned for $700 headers? I'd like to know what kind these are. If they're "shorty" style headers FORGET IT....You get what you pay for....Go with the Dynamax long tubes.
