    Great Exhaust
    Great mellow sound with no drone. Had one muffler rust on a seam, customer service was great and replaced quickly. Great customer service.

    Perfrorms and Sounds Great
    It was easy to install and came with all the necessary bits. It sounds really great to me, just a small but deep rumble and I can also feel a minuscule increase in power when I'm driving through the mountains where i live. If I can sense or feel any increase in power/torque at all by just changing my exhaust, I consider that a win.

    Terrible Fitment Flaw
    The muffler sounds fantastic. The build quality is very questionable. I cut myself on a few rough bits of unfinished material around the seams. The biggest and most detrimental problem is the hanger faces the wrong way and the instructions didn't help at all. If you don't own a welder and circular saw BEWARE.

    I Ordered This for a Single Cab Shot Bed Toyota They Sent Me One for a Extra Cab Long Bed
    Good thing. I'm a welder / farmer /mechanic had to cut and weld tubes so the muffler fit fine, sounds great.

    Bang For Dollor
    It is a lot quieter than I thought it was going to be, super simple install done on jack stands with standard tools, if you are looking for just a dash over factory this is the one for you.

    Complete Exhaust With Header
    My fear in all this was not getting the sound I wanted and this time it worked out really well. Fit was spot on, but welded it all up anyway and the mufflers output is really just noticeable and what you hear is a low growl. I also during this time replaced my injectors and that made a big difference too with the smoothness between gears. Thank you.

    Great Exhaust Kit
    This kit was super easy to install. And it sounds great on my truck. Definitely worth it.
