Overview:

Flowmaster introduces our Flow FX Extreme stainless steel cat-back exhaust system for the 2003-2024 Toyota 4Runner with the 4.0-liter engine. This system uses a Flow FX series muffler for an aggressive sound level and increased performance. 3.00-inch mandrel bent 409 stainless steel tubing allows for maximum exhaust flow and durability. The system has a turndown style, dump exit right after the muffler to eliminate the over-axle tailpipe. This elimination of the tailpipe helps improve ground clearance and departure angle when you are driving in more extreme off-road situations. This system produced max dyno gains of 4 hp and 5 lb-ft at the rear wheels. All of the necessary hardware is included, and factory-mounting locations are used for an easy installation. Backed by Flowmaster's Lifetime Limited Warranty.

    Best Phone Mount EVER!
    I searched the Toyota forums and consistently saw this item mentioned as one that would not move on bump roads or even over time on smooth roads. It is the best and must secure mount I have ever used. It fits perfectly on was designed not to obscure the view. I have recommended this brand to everyone that I have talked to about mounts since I got. Very easy to install also!

    Works well, looks stupid with the logo display
    This fits well in the vent frame and I am still able to close my vent. I really like the mount cause it solves a huge problem of where to put my phone securely... but I also hate it as well, because of the ugly logo on the face of it. "Batdiary"? Seriously? If I keep it I will look for a way to get rid of (or cover up) the extremely unattractive logo they selected. It makes it (and my trucks interior) look loke something for a child. I give it 5 stars because it deserves better than the 3.9 it had at the time of posting this. But for the love of everything clean and classy but still needing a mount, get rid of the bat logo!

    Good, but minor issues
    The build quality seemed impressive and it felt sturdy. When installed, it definitely stayed in the air vent without wiggling or coming loose after quite a bit of off roading and driving over washboards. I returned this thing and bought the "off roam" competitor because of two reasons: 1) the ball joints don't tighten down hard enough to lock the position of the mount firmly. It grips well when you don't touch it, but if you are trying to put the phone into the mount without both hands, it shifts and moves with minimal pressure. Kind of annoying for me, I feel the ball joints should tighten enough not to budge if given a tiny bit of force or accidental bump. 2) the inner springs of the phone holder started loosening and making an obnoxious vibrating/rattling sound after about a month. Any bump or minor rough surface caused this thing to rattle like loose change in a cup holder IF THE PHONE WASNT IN IT. If the phone was in the holder it didn't do this at all. It started to drive me crazy. If you can get past these two things it's built well enough and works perfectly fine. I just expect a bit more for $50-$60.
