    i called a muffler shop and ask about a magna flow exhaust they said the could either just weld a muffler on or do custom piping from the cat back with 2.5 pipe would that not be the same as just the stock piping or not or should i just buy the magna flow cat back system from my toyota dealer

    What was the cost comparision?? What are your goals for making the swap- Power, Sound??

    Just muffler is going to be cheapest but with the least change. Between the other two- I'm going to guess it'll be cheaper for them to custom fab/weld a setup for you...but I'm not sure....That's probably the best thing to consider.

    Good luck!!!

    just having a muffler welded is essentially the same thing as an expensive catback..............its the route i always go. about the only benefit with the magnaflow catback is that its stainless. depending on the state you live in/weather you get all the time........you probably dont even have to worry whether its stainless. just food for thought.

    yeah, y-pipes made right would make a huge difference, but he was asking about a catback.......and every version i have seen of a "catback" is the the piping on after the y-pipe, basically, a piece of pipe, the muffler, then the exiting pipe. they really shouldnt even call them cat backs.

    no disagree, the y-pipe is in the catback package.

    I personally wouldnt go bigger than the stock pipe diameter. If you go bigger, for one it will make your truck sound more tinny or, "ricey".
    Also, with a bigger pipe you will gain flow but you will lose backpressure, so that will shift more of your engine's power to the high end of the rpm range. IMO, thats not very useful for a truck.

    FYI, i just ordered a SS magnaflow muffler off ebay for $69 including shipping. the sellers name is "dotcomparts". he has it listed for buy it now for $78 but i best offered him $60 and we met at $69. and they ship from the great state of SC, so that'll determine how long it takes to get to ya!!
