This is my second system, Dynomax has upgraded the clamps and muffler since my original purchase. The upgraded stainless slip over style clamps are much easier to use and install. They were a much needed improvement. The standard style clamps are what contributed to my first pipe to rust out.It created a pinch point and a great place for road salt to just sit and cling to. My first system was quieter and muffler was slightly different. The new muffler has deeper sound, and nicer polished looking finish. Overall the improvements Dynomax made are functional, eased installation and provide performance. My stock muffler and tailpipe rotted out at 52k, the 1st Dynomax system lasted 85k. Hopefully this one will out last both. This is on my daily driver, New England winters/salt. Passes emissions testing, sounds good, nice look with SS tip. Nice upgrade over stock/OEM replacement. All needed brackets, bolts, donut gasket are included. Bottom line, hard to beat for the cost and what you get, proudly made in USA.

Product was shipped quickly and arrived on time.
The exhaust system was designed as a direct replacement and as a result was easy to install. The stainless steel construction and polished stainless steel muffler looks great. However I was disappointed with the final results. I realize my vehicle is only a 4.0 6 cyl Ford Ranger but I was hoping for a better sound and performance. My truck now just sounds like a 6 cyl with a noisy muffler. I will probably end up replacing it again with another brand.

Comments about Dynomax Syst-Ultra Flo Weld:

I installed this exhaust system on my 2005 Ford Ranger.
It installed easily without any trouble, it sits up inside the frame as it should.
The sound is pleasing although I wish it were just a bit louder.

Comments about Dynomax Syst-Ultra Flo Weld:

I do not usually write reviews but thought I needed to for this purchase. have a 2004 Ford Ranger XLT and my old exhaust system was shot. I had looked at this product and read all the reviews before purchasing. All the reviews were very positive so I thought I would give it a shot. This exhaust was anywhere from $200-$500 cheaper than the others offered. I just wanted to get the exhaust back to stock or a little better in the performance category. Product was shipped quickly and upon opening had all of the parts in perfect shape. Let me tell you that this exhaust system is very beefy. They did not skimp on material when they made it. The best part is how fast I did this project by myself since it was an "EXACT Fit". I was very happy when I started my truck. The sound was exactly what I was hoping for!! For the price, quality, and easy of installment I would highly recommend this if you just need to replace the exhaust system. My only complaint, and it is a small one that I had read in several reviews, is that they did not include the spring nuts that connect the system to the catalytic converter. The bolts that I had to take off were completely rusted out and I could not reuse them. I would imagine that they would need to be replaced most of the time.

    Comments about Dynomax Syst-Ultra Flo Weld:

    I left for the local store about 5 hrs ago and tossed my old muffler in the dump 1 hr ago. Installation was easy & simple and I'm no mechanic. I had an extra pair of hands to help me so it went pretty smooth. All the parts fit well. The only negative I can think of is it would have been nice if they'd included the spring bolts that attach it to the cat - I had to buy those extra. All in all I would do this again.

    Comments about Dynomax Syst-Ultra Flo Weld:

    The order was at my house the second day. Packed great no damage. All parts in kit needed for assembly except replacing tailpipe hanger, but was no big deal and no more added expense. It was nice to have my truck back to factory specs and away from the local Muffler shop hack patch job, and back to original diameter pipe not the 5/8 inch smaller pipe the shop used to skimp. Cheap is not always better.

        Comments about Dynomax Syst-Ultra Flo Weld:

        I don't have anything bad to say about this product. The install was easy and everything fit together the way it was supposed to and appears to be good quality. However I would recommend buying a 2 1/2" metal swivel hanger to hang the tail pipe if you have an older vehile because your original hanger is most likely done for.
