          I personally welded this exhaust onto my tundra. Really brings out the noise I was getting held back by stock exhaust. Well built thing is not some cheap metal. Flowmaster has again surprised me with their exhausts. If you want a nice dual exhaust that isn't outrageously loud but will definitely be a head turner I would recommend this one. There really isn't anything on can harp on that was bad about this muffler. I enjoy the sound and am surprised that after so many products made Flowmaster still has quality products!

                I have a 1985 c10 6.2l Diesel. Vin code c . I have been thinking about replacing my stock exaust for sometime now. I want to keep true duels because of it being an older truk. If i was to purchus this product. Would it need to cut off the cadilaic converter? I didn't think so. Also the size of the pipes on my truck are the same size as the inlets and outlets. Basicly if i was to do this all i would have to do is buy some pipe. Since this this box is side by side. I would have to buy some extra pipe to run it to it. Cause the stock ones i have on my truck is on both sides. ?

                  This is not the complete cat back exhaust system and it is just the Super 40 Series Delta Flow muffler. It was developed from our Top Ten race muffler lineup for use on the street and strip. It utilizes Delta Flow technology, this muffler gives the best performance to higher horsepower vehicles.
