After watching this program I went out to look at my trucks exhaust. Mine looks almost new, except for some dirt. It's a 17 year old Tundra with 190K on it.

If you just run open headers like me you don’t have to worry about your exhaust rusting.

[freddierodriguez]

Not for the type of vehicle I’m looking for but still very informative and you come across as humble and helpful. Thanks and best wishes. 🙌🏼

[karlferdinand]

Perfect timing. Just as I caused an exhaust leak trying to install new headers

Over 22 years ago now I bought a 304 series Complete 4” system for my LB-7 2002 GMC SIERRA. It STILL looks almost as new as the day I installed it in my driveway back then. It was $720 back then, when most of the non -stainless 4” systems were less than 1/2 that price, but I feel it was plenty worth it in the long run . The old “ you get what you pay for “ holds true in most cases. Plus it sounds killer . The company was “ Hog Industries” but they went out of business not long after I bought it, probably because of the price . Too bad……😕. Anyway enjoyed this video, thanks.

Back pressure is the atmosphere at sea level pushing down your exhaust system at 1 Bar or 14 PSI. If your engine can't overcome that problem with valving it will stop even though the intake uses the same pressure. Excellent video, the bubble analogy is perfect, I'm gonna use that in my brain from now on thankyou.

[andrewdrumm]

It’s called scavenging not back pressure! To increase your scavenging you install a smaller diameter pipe to increase velocity but then it’s not as free flowing but if you go to big then the exhaust slows down reducing the scavenging effect so you need to size your exhaust properly for the horsepower you are putting out!

Manufactures switched to 400 series stainless steel many years ago, Aluminized steel will also rust just like 400 series stainless steel will rust. Muffler shops use mild steel because most do not own the expensive equipment it takes to bend stainless steel pipes. If you really want the best exhaust Borla is the one you want, they use T304 stainless steel, that is the very best you can use for an exhaust and it is also the most expensive.

Inlet nipple rusted out on a Spintech and a Magnaflow, within a couple of years. Autozone turbo has lasted 6 years, still good. 2014 Silverado 5.3. Sounds great.

[davenbennallie]

Very helpful. I believe my 2015 Ram 2500 is a turbo back. It’s straight pipe and I would like to go with a full 4” pipe instead of the 3” for better air flow.

Quick question: What is the difference in sound, etc between muffler+resonator delete+ straight pipes and tips vs muff+reson delete and "dumps" like after/behind the cab?? Whats the difference, what do you recommend?? Thanks.

I build thermocouple I work with everything from iron, 304, 310, 316, 330, 446 to Inconel it will all rust. I recommend buying your muffler and tips and going to a custom shop to build the rest of your system it can be cheaper and like with my ram I wanted true duel with a x pipe

My Chevy 2003 4.3 Astro had a pretty free flowing Thrush muffler on it, and although I am an 80's Kid, I just couldn't take the loudness any longer. I had a stock muffler put back on it, and the power increase was quite noticeable. So, I guess I was NEEDING some back pressure added back in? It ran fine before, but better now!

[rayowens]

I have to disagree with you about header length. Long tube headers are generally much better for low end power. It has to do with the negative pressure wave traveling backwards up the header tube to the exhaust valve. When this wave arrives as the exhaust valve is opening it helps to pull the exhaust out of the cylinder and in turn pull the fresh intake charge in. The longer the primary tube = the longer for this negative wave to arrive at the exhaust valve and thus lower rpm.

[djweszone]

Back presser is for the gas mileage in low hp keeping the pop out and well adjusted fuel ratio to you o2 sensors. In open thro your good for more hp.

[brmk]

The aluminized steel is already coated before the exhaust tube is made and yes it’s a tube it’s measured from the OD, not the ID like a pipe. And it’s nickel and cadmium with silica, also the stainless is manufactured the same way, it’s coated when the rolled steel is made.

I like your video. 😮 what type of system do you think that would sound awesome in my car. I have a 2019 dodge charger daytona scat pack.

[F_JSF]

Dude. What an amazing video. Thanks brother.

[crazyDIYguy]

To paint the inside of exhaust...
Install steel exhaust, start engine, feed continuous spray paint into intake. About 12 cans.👌

My 2021 Trail Boss has an exhaust flapper valve. What is the purpose of this, and is it needed? I wanted to just do a simple "budget" exhaust, replacing my stock muffler with a Borla ATAK, and not sure if that flapper needs to stay on or not.
