    Comments about Dynomax Syst-Ultra Flo Weld:

    I had this professionally installed by an exhaust shop that started my installs 30yrs ago...He knows what he is doing. The Passenger side tail pipe was pointed outwards & needed heating & bending to aim straight back. The Drivers side tail pipe was DIRECTLY aimed at the tow hitch so it had to be heated & ben out to go around the hitch then heated & bent again to exit straight back instead f to the rear corner of the bed. All in all it was pretty of an install although my installer would have preferred to bend up a kit himself instead of installing this "pre-made" kit. Having to odify no longer qualifies as 'pre-made' in my eyes. And the muffler is quiet, real quiet. From directly behind the truck it sounds decent but I drive from inside so.....And even then I think it is too quiet. I will be changing out the muffler to a Magnaflow bullet muffler w/y-pipe (for the dual rear tips) later this year. Or just put on a QTP electric cut out that I can open & close from the drivers seat from just a little to fully open to adjust the sound level to my desire or fully closed when the need arises but that is $223+install so that option is farther down the road & would have been cheaper to do in the first place.

    The sytem is easy to install and sounds great. The mandrel bent tubing makes this an extreme value.

        Comments about Dynomax Syst-Ultra Flo Weld:

        Very happy with the apparent quality and finish of the system (it's stainless and mostly made in USA). I was very patient with the install and took my time to fit and tweek before committing to final tightening (followed instructions) and very satisfied with (recent) install - we'll see if it gives me a little more MPG... The sound is a nice rumble compared to the whisper of the stock system but this system is NOT loud at all - only slightly louder than stock, but with a nice rumble that doesn't drone out and resonate in the cab on the highway. I would give it 5 stars for fit but had to work around my factory towing receiver on frame (only affected how I ran the tail pipes) and I couldn't mount the last few feet of the tailpipes as close to the bumper as I wanted - still looks great.
