Hi, ive been reading about exhaust for my 2000 v6 for about a month now....some days i read articles saying that a 2.5 inch system is too big, and you will loose power and other days i hear it is good....i also hear that a 2.25 inch system is good.. My options as of now are to buy a friend of mines old exhuast off his gt....it is a 2.5 magnaflow stainless steel with 3.5 inch tips. I also can go for the stock gt take offs which are 2.25 inch. I will be able to get either system for $120, so what do you think?
It all depends on what you are going for. If you want the best possible for a mostly stock V6 that you plan on just a filter/intake and exhaust, then the GT take off will probably serve it's purpose. But if you plan on having more mods or you want a louder, deeper sound, the magnaflows will work best. In all honesty, you're talking a few ft-lbs of torque movement, it's not lost, it's just moved up the rpm scale. I have basically the GT take off, and the sound sometimes leaves alot to be desired volume wise and doesn't have as good of an idle rumble.
Dude, if you can get the magnaflow GT system for $120, buy both and sell the magnaflow system for twice as much on ebay - then you break even and end up with a GT exhaust for free!
Personally I would only go with 2.5" if You were planning on a Power adder like a SC or Nitrous down the road. Thats when the bigger exhaust will really benefit you, otherwise its a waste to lose that little bit of extra torque down low.
4 inch after your y pipe i saw it on speed vision so i think that you should do it maybe you might rumble like a v8!!!!
Go with the Magnaflow since it's the same price. What little bit of low-end TQ you might lose with 2.5" diameter pipes you can easily get back by going to 4.10 rear gears
