I didn't hear any sound from TRD Exhaust and heard it's just the sound that is the actual improvement but doesn't heed a noticeable improvement in performance, fuel economy, hp, tq. etc.
Just to clarify, not all AFE filters are the pro-dry s type. AFE also makes a wet gauze (like K&N) type. 007Tacoma is running an AFE wet type, and has checked it several times and there is no oil build-up on his MAF sensor. I chose the pro-dry S type because I have personally had problems with K&Ns in the past, and wanted a dry type Amsoil filter, but they don't make one for the gen 2 Tacos so the pro-dry S type of filter seems to be as good or better from what I can find so that is what I went with.
As far as the K&Ns go, I have heard from several people that A.
K&N filters do not filter as well as others (read as lets more dirt into the engine, causing possible engine damage, and B.
K&N filters let some of the oil through the filter which then coats the MAF sensor and screws with the readings. I do not believe that this causes damage to the MAF sensor, and that once you clean the sensor everything will be fine again, however, for my liking that is too many "cons."
As far as the TRD exhaust goes... Some people bitch that "it is nothing more than a sport muffler, you get no better (read as bigger) tubing. I suppose that is technically correct. The stock taco pipes are 2" Mandrell bent tubing (I believe aluminized steel but don't hold me to that). The TRD pipe is 2" Mandrell bent Stainless Steel with a higher flow sport muffler. So no, you are not getting a 3" of 4" pipe with the TRD, but realistically you don't need or want something that massive on anything short of a duramax diesel. An engine needs a certain amount of back-pressure to operate correctly, so in all likely hood unless your engine is heavily modified you would be loosing power with anything larger.
As far as the TRD clip. I just checked it and it plays here, though it is recorded kinda soft so you have to turn up your speakers quite a bit.
