Was thinking of a Flowmaster 40 but have been hearing that it's quite loud and there is low end power loss does anyone have any experience with the 40 ?

It "can" be loud, but it isn't always that bad.  I have seen people who dumped the pipes over the axle, or have done like mine, and run the pipes out the back.  If you dump 'em over the axle, it uses the cab as an AMPLIFIER and it REAL loud, inside and out.  

My truck, with the pipes out the back, it is not loud in the cab at all, EXCEPT at hard acceleration (but I don't do that too often).  

But this is all dependent on what you think is loud!  At what volume do you listen to your radio?  :)

My $.02, hope it helps...

polxc5,

Welcome to the site.

I have a single in/dual out 40 series and agree with what kaspar139 said about the loudness of it.  I like it alot.  As far as losing low end torque, I've heard of people noticing it but I havn't been able to tell.

I have the single in/ dual out 40 series (Not Delta Flow) as well. My tailpipes dump down just behind the spare tire (see pic). I love the sound too!  Not too loud on long highway trips and gets some looks around town.

Thanks for the info - you recommend the cat-back or just the 40 series muffler ?

 

I don't have any experience with the Flowmaster Cat-Back system, so I can't really say.  I've never even seen or heard on that I know of.  Sorry.

i have the series 50 and it can get a little noisy -- especially around town where you're accelerating so often.  it can get a little difficult to hold a conversation in the cab.  

That said, i'd do it again any day of the week.  i got a big kick in the shorts and when you're alone and conversation isn't important, it sounds really cool!

i went to a local shop and they bent everything right there for my truck -- even came with great tips -- all for ? had it done in an hour or two.  the specialty shop wanted ?+ for the cat back system from flowmaster.  save the ? and you can put it into a K&N or an appearance dress up!

      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.
