I want to get SIDO rear angled side exit (one behind each tire). I have an 05 with tow package and 18" spare.

I contacted Magnaflow who was going to get back with me, but hasn't returned an email or phone call. Do they not want the business?

Local shop will do it with flowmaster, but I'm told by everyone on here that flowmaster will decreases performance..

What's a man to do? Does Magnaflow make such an animal?

EDIT: I guess this should be in aftermarket exhaust forum.

 

Anyone that tells you flowmaster decreases performance should have their players card revoked.

For the most simplistic explanation, look at the 8-10 second 1/4 mile mustangs. What do they run? Flowmaster, Borla Now look to the 13-16 second ricers, what do they run? Magnaflow, and some things you can't read.

All performance mufflers are designed alike.....I said alike, not the same

Here is a flowmaster chart of their mufflers.



Camparison pictures of the two





As you can see, the magnaflow has a typical ricer style straight through pipe with steel wool and fiberglass (that they call sound suppression material)

The Flowmaster is a real muffler, with baffles and turns.

Magnaglow cost: $620 plus shipping and install
Flowmaster American Thunder Exhaust Systems from summitracing.com $369 + shipping

 

I put a Flowmaster Cat-back system on my truck and in about 1.5 years the Flowmaster muffler rusted out. I had it replaced with a Stainless steel Magnaflow SIDO muffler (5x8x14) and I love the sound. Similar to that of the Flowmaster 50 series, but a little bit deeper with less interior resonance. It feels like the low end torque has increased, but I can't guarantee that because I haven't had the truck on a dyno.

 

I had the Flowmater installed at a muffler shop. If it decreased anything, not enough for me to notice. It will still burn rubber from a stand still and sounds great to me. If the Magnaflow performs better, it isn't enough for me to justify the extra cost.

 

I had a 1714 tuner and K&N drop-in filter... then added the Magnaflow cat-back kit. Definitely more punch and nice mellow growl. I think it really boils down to what kinda sound you wish to get out of your tailpipe.

And the clown that associated Magnaflow with horrid ricer peformance should have his players card revoked. Seriously. And Borla is even more expensive than the Magnaflow setup. I don't think you can go wrong with any of the three, and be sure to look into others like Bassani, Gibson, and more! You have a lot of choices, search and decide!

EDIT: Oh, and I paid under $400 for my setup, shipped.

 

anybody that says flowmaster will decrease your performence is wrong.if it decreased their performance it was installed wrong. only a dyno could tell the difference not somebody driving around. make your decision between these 2 based on sound. a good local muffler shop will save u $$$$$ just call and ask.

 

I can see where someone would want a few HP here and there, after all small numbers in large quantities add up. But in all honesty, 10-40hp isnt going to be enough to raise your performance enough to notice. But like I said, that coupled with some other hp gains is always a GRRRREAT thing.

 

D - Who did you buy your setup from? I'm looking to do this very soon.

Once you pick your kit out, add it to the cart, then click on the 'add coupon' or something link just below. Type 'fordtruck8' and OK. The total should be just shy of 4 bills and you get free shipping! Woo-hoo!

 

Wow.. Awesome.. Thank you...

I still need to decide what I'm going to go with, but thanks for all the input you guys!!

Not really caring about the performance gains, I just don't want any decreases.

Not sure which flowmaster series would be good though.. Low interior res, medium throaty sound.. thinking about a 50 series?

 

D - Thanks for the feedback and that coupon saves a bunch of change. Heres a nanner for you!

I want to do the Magnaflow dual exhaust (16614) but I keep reading its not feasible for those of use with the trailer hitch. Guess I might have to settle for the SI/SO (16612).

 

I think there are quite a few members here with tow package and dual exhaust...

 

Well, this clown that associated magnaflow with ricers did so for a great reason, apparently you don't understand.

Magnaflow is the most purchased system for Honda/Acura vehicles on the market. Naturally, they are going to put the most effort into their products that sell the best. Flowmasters biggest seller, is the ford Mustang. All of its deepest research goes into that car, or the 4.6 motor, which is all but alike the 5.4. So, since flowmaster is centered around a modular ford motor, and magnaflow is centered around a japanese motor, which system is going to fair better in the long run only looking for performance standards? I think thats about as simple as it can be written, and disagreeing with such shows a complete lack of the understand of business and the models they use.

Now, if you live inthe northeast, colorado, ND, SD, or somewhere like that, then maybe a stainless system is better for your application due to the conditions you'll face. But the obvious answer to the question that you seek is that Flowmaster should be your choice. And you can buy it from www.summitracing.com for between $272-$416 + shipping, which you'll get free with a coupon from the back of the summit racing book, and if you don't have one I'lll be happy to provide you with the discount code.

 

Puh-leeze. By your logic Ford cars are sh*t since they sell more trucks than anything and most of thier R&D dollars go towards it. The mustang is a pile, so now Flowmaster is wasting its R&D dollars on a POS car made by a truck manufacture.

And Flowmaster offers about 400 different exhaust systems. So the other 399 flowmaster buyers just got F'd over by Flowmast since they don't drive a mustang? Give me a break. There are many great exhaust companies out there that work their butts off to design and test their systems for added HP and sound. Take stock vehicle then dyno them with a Magnaflow & then a Flowmaster... besides the sound I bet their numbers are within 2-3HP of one another.

It doesn't take a business degree to understand your logic on how to buy a muffer is seriously messed up.

 

You must live in a 1D world don't you? What made Flowmaster? Mustangs on the track. What made Magnaflow? Ricers. Whats 2+2? Hint, it ain't 6 like you think.

All of the R&D gained through the mustang is then applied towards, um,the F series truck since it has always had a common engine. (display your sign )

And if the Mustang is a pile I guess the ford 8.8 rear end in your truck is trash, the 5.4 Cobra motors is junk, and all the other parts are just dead weight. You should try thinking before you speak, you'd sound alot smarter. You smack down the roots of your truck and its powertrain and all the R&D ford put into another one of its cars and applied to the trucks. You smack down the car that started the revolution of performance, and that very revolution trickled down yo your truck and provided you with performance parts and accessories. And if you don't see that, you are a damn fool.

Don't I know that Ford Makes Trucks? Well, duh, you don't need a marketing degree to know that. ANd flowmaster makes just over 370 systems.

You may not need a business degree, but what you do need is a degree in common sense. I'm not here to argue with someone who wants to have a pissing contest about why one company is better than the other. I'll even conceed that magnaflow will probably get 1-2 more HP from their products. But when it comes down to it, IMO, it comes at a greater cost financially because they cost signifigantly more, and later on it costs more longetevity wise as their products are straight through, not baffled (thats due to reduced exhaust system back pressure, the longetevity issue)

All I want to do is help this guy know all the FACTS about the different systems. I have experienced both products, and the clear winner is Flowmaster
