Actually, at the Muffler Shop I go to, they have an X-PIPE which you can buy by itself.. The part is a exhaust pipe X.. They weld it into the existing straight dual, which should only take about 30min.. What us V6 owners must remember, is that the way our engine is designed, if we do not allow both sides of the manifold, to work together, you must give up the glorious True V8 sound.. Also, I am here to tell you, that the power you guys have now in the car will diminish should you choose a true dual setup.. Meaning staight pipes, that never intersect.. In a V8 engine, this would not be a problem, in regards to sound.. But the V8 would suffer the loss of power at the lower end.. I am forcasting more low end torque than stock and more high end HP as well, once the X-PIPE is installed.. I believe, with the 2005 V6, this has been one of the most important discoveries or discussions to date.. By me needing to feed my hunger for more power, I over shot my goal, to the point of lost HP and torque.. Learning from my mistake and sharing it here, has made it all worth it.. Which is why these types of forums are awsome.. Typically, when you make this kind of mistake, and overcome it, the method is kept to yourself.. In this case, all my V6 brothers will never have to suffer from this type of mis-informed calculation based on our particular engine needs and requirements.. You better believe, once this is straightent out, I am going duck hunting.. LOL!! Meaning the poor sucker with a V8, sitting at the light next to me, once the X-PIPE is installed, will have to eat asphalt once I dig my 255's into the pavement!! LOL!! What I really love about the V6, is you cant be as careless as when you have the all out muscle V8.. With the V8 stangs, you can make mistakes, an it may not be as apparent unless you make 1/4 mile passes.. With the V6, all of our upgrades must be well informed.. We dont have enough power to squander.. We need every bit of what Ford gave us, and must work even harder, to find more! It is indeed challenging.. My goal, at some point in the future, is to take down a 2005 V8.. This will indeed be a very tough task.. How much money it will take to complete the task, I have no idea at this point.. But I am already $350 in.. The X-PIPE, plus installation, will cost me about $100 bucks more.. My next purchase will be the ECM computer, so I can remove the top speed limit, and maybe re-calibrate while at a stoplight.. LOL!! This is indeed going to be a very fun summer... Also, once it is done, I promise to get the car dyno'd with all the relavant information to post..
