    Good Piping & Sound, Lousy Instructions.
    I bought this system for my '04 federal emissions LB7. I wasn't sure how good of quality it would be for only $400. Honestly I'm pleasantly surprised how good it was. The clamps are better quality and the piping is thicker than anticipated. My only two complaints are one of the hangers doesn't work (the one just forward of where the stock muffler sat), and the instructions are very scant (essentially just "take out the stock system, install the new system front to back"). That being said, I would still buy this system again.

    Unbelievable!
    This is the cleanest and easiest kit to install and modify if need be! If you're pushing some serious horsepower, look no further than the 5" builder series from TRUCKiD.com made by Magnaflow!

    Sounds nice!
    It makes my vehicle sound just the way I like it. Take it or leave it but I got the one I need without any advices. I don’t need any help to choose the best product. Ordered on Monday, got on Friday like clockwork.

    Did this in my driveway one man. Took me a day and a half to cut the stock pipe from the cat pipe back off. Had to manage how I cut it because it’s a little lower but I have a 3 level on it. Ended up cutting it in 3 pieces. Then used a helper to install the magna flow adapter back to the end of the new muffler to hold. All and all it’s good.

    So Far So Good
    Was a bit louder than I expected when first installed last year but now just sounds fine and is working fine with no rusting or any other issues. It looks nice when you see the MF logo on the tailpipes that implies you are cool and like dirty abbreviations!

    Sounds Awesome
    Put this on my '24 Ranger. Not too loud, just right. Wasn't sure at first, but this exhaust is good. Never had issues ordering from these guys.

    Great
    I use my 4runner for both commuting and weekend trips. This exhaust system is quiet enough for daily driving but with a nice rumble when I hit the trails. The fit is spot-on and the sound is just right. Satisfied with my order.

    Great sound, easy install
    Installed this exhaust myself in under two hours. The sound is perfect, not too loud but definitely more aggressive than stock, you can definitely hear it when you step on the gas.
