Any suggestions? Why? OBX, Pacesetter, Manzo and others. I'm looking to do a cam swap and have everything except the headers.
I have heard others say that the factory pipe is wide enough for most people who are not making huge power. Lots of people upgrade the headers and muffler and leave the factory pipe.The biggest flaw I see on most of the included y-pipes (including Speed Engineering) is the merge from the two 3" down to a single 3".. wtf? Granted that this works for hooking it up to stock single pretzel-twisted 3" exhaust, but it doesn't take the head-cashier at walmart to understand that this is like pissin on your boot to keep your foot warm. If you're going to the effort to put headers on, then man/woman up and convert the merge into a dual 3" in/3.5" single out at a minimum. I recommend going to a single 4" out though, with one 4" race muffler.
There is nothing wrong with running 2 pipes into one.. I'm running the dual 3" pipes that come with the speed engineering y-pipe, but cutting off the dual 3" to single 3" collector, then replacing it with a dual 3" to single 4" collector, then 2 feet of 4" pipe to a 4" Hooker Maximum Flow Muffler (best muffler ever, best sound, most power, just search the forums for a clip) and then im dumping the exhaust just before the rear axle.I have heard others say that the factory pipe is wide enough for most people who are not making huge power. Lots of people upgrade the headers and muffler and leave the factory pipe.
I realize that it seems silly two reduce two pipes down into one, but isn't it more about the exhaust requirements of the engine?
I'm no mechanic, so I apologize if I sound dumb. I'm just curious.
