    Dynomax Cat back system # 39315
    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.

    Disappointed with the outcome
    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.

    Nice sound
    Sounds great on my 4.0L Ranger. My original system had rotted out from the cats back, so I need something new but didn't want to lose the mild rumble it had developed. This worked perfectly, slight rumble at idle, pretty quite while cruising and sounds awesome when accelerating without being really loud, just a nice powerful sound. Only issue was the clamp for the tip is a little big, just remove the hour glass shaped piece and you can tighten it up good.
    Bottom Line Yes, I would recommend to a friend
    Good sound and great value
    Verified Buyer -
    The product was stated for a 98 Ford Ranger, but fit perfectly on my 98 Mazda B2500. I was pleased with the sound its mellow,not quiet not loud.
    Bottom Line Yes, I would recommend to a friend
