My dad just called me and got some prices for bolt on dual exhaust. He settled on a Flowmaster 817691 system in stainless steel....
Just wondering if he should stay with it or listen to me and go both a different brand. I'm against Flowmaster so I do not recommend them to ANYONE

 

I was anti Flowmaster after my 3 year old SI/DO series 50 rotted off of my 03. Don't know if their stainless is better but I have a Borla on mine and will not have to worry about it till my truck rolls past 1,000,000 miles

 

Magnaflow, SLP, Borla, etc are all high quality parts. Flowmaster isn't bad but also isn't quality; they're just okay.

Sound is subjective, so I won't waste time talking about that.

 

Never had good luck with flowmaster but that was years ago. Maybe they've improved quality. I live in the rest belt and the Borla setup on my last truck look great after many winters. If I get a system on my current truck, it will be another Borla, no question.

 

Yeah I have a stainless single exit borla on my 04 f350 with 5.4 for well over 10 years now here in south Jersey. And it still looks brand new! I told him to get a differnt exhaust but o well

 

I've got stainless Flowmaster 10's on my 2011 F-150 5.0L that have been there for roughly eight years and about 63,000 miles (truck had about 8,000 miles on it when I had them installed). I have zero complaints during my time of owning them, No rust, no exhaust leak, no nothing, they still sound great to this day. I do think the Borla ATAK and the Dynomax Bullets sound fantastic, maybe to loud for some but they have great sound. The main reason I went with the Flowmasters at the time was price, I think my whole exhaust set up cost me right around $300 if I remember correctly. Not a bad deal for 8 trouble free years of loud pipes.

 

Just figured I'd post a update, well my dads had the exhaust for a while and I think it sounds like CRAP simplest way to explain it is when someone cuts the muffler and cat off their truck and you get that raspy obnoxious loud no tone exhaust....yeah that's what it sounds like.

 

But how does your Dad like it?

 

If u end up changing it, I recommend BORLA S-Type. I promise there will be NO raspy sound & its high quality SS

"Material Difference:
Many new-model cars and trucks come factory-equipped with a low grade, 400 series stainless steel exhaust. These are an improvement from the old, rusty steel systems and are built to improve durability somewhat. Also, the inferior grade of stainless is the only cheap material that will last through the factory warranty period. But, ferritic stainless steels, which are part of the 400 series of stainless alloys, are magnetic, as compared to Austenitic stainless steels, which are part of the 200 & 300 series of stainless alloys and are non-magnetic. BORLA® incorporates Austenitic stainless, which is superior for automotive exhaust because it exhibits higher hardness and yield strength as well as excellent ductility. And, the higher nickel and chromium content makes it much more resistant to corrosion. Because these austenitic alloys are higher grade materials and harder to work with, they are therefore too expensive for the OE to supply.

High quality, austenitic stainless allows us to back our systems with a Million-Mile guarantee - A BORLA® is a lifetime system!

Performance Difference: BORLA® exhausts are also tuned to maximize the performance output of your vehicle and feature a more attractive and cost effective package than stock."

 

I love my Borla Touring

 

His words were its ok....but its not my 7.3

 

5.0s will sound very different than a 4.6 or 5.4, all else being equal. Listen to OEM Mustang GTs of both varieties for example.

I know a 5.90 will scoot, but I'm not a fan of their sound.

Back a few years ago, bought a 100% SS system from a relatively unknown "Legato" comp[any, I think it was very much same as FlowMax … it was deep throated, but too loud with drone in the cab. I added a stailess steel 28" long 2-1/2" cored cherrybomb ahead of the short muffler, it helped. Then I added weights to the pipe between the cats & glasspack cherrybomb, and that killed the drone. Just a nice mellow sound.
