Well i am planning on getting a new exhaust. I want dual outlet from the muffler, and am thinking flowmaster. I have found a couple that bolt up to the factory single Cat. OUtlet but i am not sure what size outlet the is. I was told three but am not sure. Any suggestions or other idea's would be great, thanks.

I'm also looking for suggestions on a catback exhaust system. Is it worth buying on a 4.3? Would it make my truck sound like a Honda? Any info you experts can provide is greatly appreciated.

Best thing to do is to have a look underneath and measure the pipe.

However, I'm quite sure the pipe will be 3".

There are a few threads on this forum where people have posted sound clips of their trucks. I'm sure there were a couple of 4.3 and they sounded ok.

How loud do you think it would be if i ran straight out of the cat. converter?

 

On my 99 there is a disconnect between the cats and the muffler, disconnect it there and see how it sounds.

On my 2001 5.3 I had my exhaust guys cut the y pipe after the cats, cause I have dual cats, and ran 2.5 inch pipe back to the rear axle, than down sized to 2 inch over the rear axle, and went back to 2.5 inches out the back. It is a little louder than stock at idle, but not much, and a nice comfortable level while crusing around easy, but gets nice and loud when I get on it. I the boys in blue haven't messed with me about it ever, and I have been running it like that for 3 years, but I am getting ready to redo it cause I am putting full length headers on it, either I am gonna fork out the cash for the Supermaxx set or I am gonna go with the Thorley tri-y, High flow cats, and 2.5 all the way to the rear axle, than down sizing to 2.25 inch over the rear axle and out the back with some nice crome tips. the will make it louder all around, but that is the way I like it.

      The Peckish Synapse

      By Grumpy Bear · Posted

      You're better read than that Atlas. 😏   British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law – that "any sufficiently advanced technology is indistinguishable from magic" – is the best known and most widely cited.   Stribeck and the pivotable Hersey Number isn't voodoo nor snake oil. That part is physics. It's what marketing and bean counters do with it that is snake oil and voodoo.    Stribeck is the relationship between Hersey and the Coefficient of Friction. Within the Hersey Equation if viscosity and viscosity is 'Dependent' on.......heat.......and.......viscosity index or the temperature to viscosity slope.    Specifically Hersey is the viscosity AT THE TEMPERATURE IN THAT LOCATION FOR THAT SLOPE.   Hydrodynamic lubrication exist when the film thickness in the location is 3X the Ra roughness of the surface. This is irrespective of the hardness of the substrate. To obtain that thickness X viscosity is required for Y velocity at Z load. That's a lot of moving parts. It is also impossible to maintain in an ICE but nearly possible with a turbine under constant load.    What does that mean? Error heavy and operate light. Wear is inevitable but the rate of wear and the milage obtainable are a function of prevailing conditions and HABITS. The only penalty is viscous drag and at fractions so low as to be well worth the effort. Double the life, half the manufacturing carbon foot print. Greed is the only impediment.    The materials generated by SwRI are the RESULT not an estimation or a hypothesis.    Don't delude yourself sir, EV's have as many pitfalls as ICE's. We just don't know what they are yet and it will take longer to sort as MARKETING and GREEDY CEO's have had more time to polish the turd they are selling.

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.
