Has anybody put an after market spoiler on the Charger yet? I called around and somebody gave me a quote of "around" $500 but I don't think that was a firm quote.

Does anybody know if there is a performance chip out for the Charger R/T yet? How much do you think that will cost?

    2 reasons:
    1 is that most aftermarket manufacturers don't go through the rigorous development and testing that the car's manufacturer does when designing the exhaust and intake. therefore, an aftermarket part is not always better than stock.

    2 is that bigger is not always better. When you are dealing with an NA engine, a certain amount of backpressure is needed for the engine to operate optimally. If the exhaust is TOO free flowing, then you are not getting enough back pressure for the engine to burn the fuel efficiently. And for the intake side, it needs to be designed for optimal airflow and keep out as much engine heat as possible. Again, not all aftermarket systems are designed properly.

    Is there an aftermarket modification available for the R/T (Daytona) to give this vehicle a little more rumble of the true muscle car? I got rid of my old Z28 and recently drove the new GTO and both had more of a rumble that you would think a hemi would??
  • If you mean more of a muscle car sound. I used the magnaflo cat back exhaust system for the charger and then I put a AEM cold air intake setup on it. hope that helps.
  • Just wanted to know why you picked magnaflo over Borla? I was planning on putting at Borla exhaust and a K&N cold air intake.

    Do you have a new chip?

  • looneytoonlooneytoon Posts: 14
    the Magnaflo has more horsepower and a deeper sound at higher RMPs then the Borla. I like Borla but in the case of the Hemi you are only buying a name and not true performance.
  • Hello All,
    I have been reading this forum, and it seems that some of you suggest not installing dual exhaust on the SE. I have been looking forward to installing dual exhaust on my SE for months, not only for Hp boost, but for looks as well. Is there no kind or type of dual exhaust anyone can recommend for the SE? Or should I give up on it??? Note, doesn't some SXT models come equipped with dual exhaust? Does that factory OEM kit give any kind of performance boost? Help me please, with my exhaust dilemma!

    If you read loneytoon message 887,893 you will get your answer for your exhaust question,I have a SXT and they don't come with duals.I'm leaving mine stock,I tried a K&N and it was a bad idea,I lost performance and MPGs.Good luck
  • losskilosski Posts: 12
    Did you try the duel exhaust? I'm in the same hole you are in.
  • sgpd101sgpd101 Posts: 3
    I did not change the exhaust. After reading all the feed back from people on this site, and all the problems that some people had with loss of power and things, I decided to just leave my TOP BANANA just the way she was. I loved her whey I bought her, so as for right now, I am just going to leave well enough alone.

    If you change yours and have a positive out come, let me know. I was looking at "flowmasters" from ebay they were $789.00 and free shipping.

    Best of luck and keep me updated.

    I have a Charger SXT and I have had the daimler dual exhaust installed. I addition, I installed a K&N filter. I have a noticable performace increas e. It looks and sounds fantastic, and have had numerous compliments on it. The factory dual exhaust is designed for the car. While I appreciate those who suggest not to get it, there opinions may be more accurate for aftermarket systems. If you are thinking about getting dual exhaust system, go for it, you will not regret it!
  • raybanrayban Posts: 6
    Has anyone with an SXT or SE added the nicer R/T shift console bezel. It looks much nicer than the black trim one. If so, is it easy to take the old one out and pop the new one in. Is it an espensive part? Thanks
  • How is it that so many people (on this and a few other forums) are saying that they are losing performace and mpg with upgrades such as exhaust and intake? :confuse: I thought that exhaust and intake could only make and engine better, as my dad always said, "more air in, more air out"... :surprise: I think it could be because your not going all the way, perhaps if one were to install headers all the way thru to true cat-back dual exhaust... with cold air intake then the performance would surface? ;) I don't know... any thoughts? I personally am looking forward to installing duals and intake but now I am all :confuse:

    Hey I'm considering purchasing an 06 Charger. I want to add exhaust but I'm torn between Borla and Magnaflow and does anyone know much about rims? I want to go with 22 inch wheels but I've heard that they can scratch when you take sharp turns, does anyone know anything about this? If that's the case what about 20 inch wheels? Thanks...
  • daffindaffin Posts: 30
    The SRT8 comes standard with 20 inch wheels. I've read that the '07 R&T package for the R/T may also come with chrome clad 20 inch wheels. Beyond that, I know nothing about how large you can go with aftermarket wheels.

    While I haven't studied the any of the four engines that DC is putting into the Charger and its siblings, I do have a considerable amount of research history to offer an opinion as to why a large free flowing exhaust system can in many cases yield lower fuel economy and lower power at any given throttle setting.

    1) Exhaust system harmonic resonance. This is a huge issue in 2-Stroke engines, and manufacturers spend considerable resources to tune the exhaust system such that the shock wave inside the header rebounds in such a fashion to actually aid in cylinder packing (volumetric efficiency). As any of you 2-Stroke dirt bike riders can attest, there is usually a fairly narrow "Sweet Spot" in the power curve where the power spikes. Said power spike is usually caused in these engines by the shock wave of the exhaust pulse rebounding off the back side of the exhaust chamber and then "pushing back" toward the exhaust port. As the intake port is almost always open before the exhaust port is fully closed, the combination of the pressurized intake charge and the rebounding shock wave leads to greater cylinder packing.
    2) In 4-Stroke engines it was long ago found (like in the 1920s or 1930s) that engine efficiency (via better scavenging) was improved by opening the intake valve before the exhaust valve was fully closed, thus using the intake charge to help "Push" the remaining exhaust out. This technique is commonly referred to as "Valve Overlap", and my guess is that all of the Charger engines are so designed.
    3) Assuming the Valve Overlap scenario holds true for the Charger engines, then by replacing the stock intake and exhaust system with "Better breathing" hardware, you will most likely find that the larger intake charge meets far less resistance in the combustion chamber during the period of overlap because the better breathing exhaust system is allowing too much scavenging. Said another way, with better breathing, you are effectively pumping a higher than optimal percentage of your unburned intake charge right out into the exhaust system before the exhaust valve closes.

    Regardless of how the engines are designed, the bet is that DC has tuned the harmonics of the intake and exhaust to match as best as possible the rest of the engine. To the best of my knowledge, the only way to successfully utilize a freer flowing intake and exhaust system is by installing a cam specifically designed to compliment the new plumbing (i.e. given the better intake flow and the better scavenging, the new cam will provide for a shorter period of overlap, or even eliminate the overlap all together).

    Once again, I have not researched these engines enough to know if my theory is true, so please don't quote my brief thoughts as fact.

    Let the discussion begin. ;-)

    Best Regards,
  • losskilosski Posts: 12
    Glad to know it worked for you. I'm go to get it on my charger also. You installed it for you? What was the price?
  • losskilosski Posts: 12
    I have 22" on my charger and it's fine. you can see my car on
  • losskilosski Posts: 12
    Where can you buy it from?
  • xtecxtec Posts: 354
    You have a nice looking ride,I think you should put on a SRT spoiler and finish it off.I added one on my SXT and it made a big differance on looks.You can see it on mycarspace.I got it from and paid $288 painted,a perfect match on paint with a 5year warranty.
  • losskilosski Posts: 12
    Thanks for the info on the spoiler, I'm going to buy one and put factory duels on it also. :shades:
  • raybanrayban Posts: 6
    I paid $415 for the parts ..the dealer charged me $140 to install..about an hour and half wait.
  • raybanrayban Posts: 6
    I priced it out from a dealer...if you want to put R/T parts on an SXT, you need to find the VIN off an R/T to pull up the parts on their computer. The cost is $146. Does anyone know if the shift console just pops off...I quite sure its just a pressure plate that holds it on.
  • losskilosski Posts: 12
    I'm ordering my Exhaust on Monday from the dealer for $425 and a Exhaust shop will put it on for $100. Dealer said $79 an hour. :cry:
  • Hi Shipo,

    Thanks for an excellent post, and allow me to add a few things.

    First, rest assured that any engine produced for the purpose of daily consumer use is far from utilizing an idealized harmonic resonance relationship in its intake/exhaust systems. Critical tuning such as what you are describing will exist only in the most carefully engineered and contemplated internal combustion engines (read: Ferrari, Lamborghini). The fact that John Q. Public can go out and slap a simple K&N filter on his V-8, along with a crummy Chinese exhaust system, and see a 15-30 hp increase is testimony to this fact. Trust me, DC, GM, Foad [sic], and whoever, all know how to make their engines produce more horse, but the reason they don't is simple; Engineering Economics, a.k.a., " the cheapest POS that will still get the job done, and get it out to the public...". The intake and exhaust systems sold with 99% of the vehicles today are produced with far more emphasis on cost reduction than they are in making power. This is (again) why aftermarket manufacturers such as Flowmaster, GHL, Corsa, etc., all can make a living - because John Q. Public is doing far more to assist the acoustic performance of his engine by removing the factory parts, than he is to hinder it.

    Just my two Euro.

  • Went to the dealer this morning, 7:00 am sharp, and bought the Dual Cat Back Exhaust kit (# 82209611) for the V6 3.5L Charger. Arrived at "Awesome Performance" (near work) and they started installation at 8:15 and completed at 9:00.

    Kit Cost $426.00
    Install $120.00 (Dealer wanted almost $300.00)

    Sounds Great.
    Looks Great.

    I am VERY happy...... So far.....
  • I am EXTREMLY pleased wih the dual exhaust. It sounds totally awesome. It looks great. And best of all, my car no longer hesitates when stepping on the gas. I don't have any data (numbers) on the actual improvements, but the car is extremly more responsive now. (Sorry for using extremly twice).

    I HIGHLY recommend it, if you are on the fence. It exceeded all my expectations...
  • losskilosski Posts: 12
    I did the same thing and i am Very happy also. :shades:
  • xtecxtec Posts: 354
    Let me know if there is a differance on your MPG.I don't want to invest that much money if the mileage doesn't go up.
