D- I think its time for a mule kick!

 

 

Ricers made Magnaflow? Mustangs on the track?! WTF Mate?

Flowmaster started in sprint cars, making them QUIETER. Nowadays they do everything in the lab with hi-tech gadgets (just like Magnaflow and others) for hundreds of vehicles. 370, 400... whatever. You horrid logic makes anyone look smart.

cscoios, I think your right... it definitely qualifies as "pointless drivel"

Here you go you exhaust fume smelling nutjob!

 

I just spent the last hour putting on my Bank's Monster. It has excellent clearances and it sounds great. $470 shipped from Bank's.

 

98Navi, you should really stop before you make a fool of yourself. My girlfriend had a 50 Series Flowmaster on her 2002 F150 and it sounded weak. I changed it out for a Magnaflow muffler and the difference is clear. The increase in low end response is noticeable over the Slowmaster. Throttle response has improved as well. If my auto-illiterate girlfriend can notice the difference (especially getting on the freeway) I doubt people here are dreaming about the increases they experience. You obviously have no experience with the Magnaflow brand to spout such nonsense.

 

I had a brand new flowmaster and threw it in the trash (chambers are restrictive). I've "NEVER" seen a Magnaflow on a Honda? Magnaflow is quiet and doesn't make bumble bee fart cans.

I made my own custom dual in/out Magnaflow with an addition "X" pipe and it blows away my old exhaust (night & day).

 

Yes, flowmaster started on sprint cars. And of course anyone could read their about us page and figure that out. (2.5 inch pipe)

Lets take for example a stock 2001 cobra. (this is just the example I found to show, the car itself doesn't matter) Flows are as follows:

The stock muffler flowed an average of 174.96 cfm
Magnaflow flowed a an average of 284.32 cfm!

Thats great isn't it!! That should mean bags of HP gains!! Well, no it didn't.

266 rwhp and 271 rwtq in stock form
Average hp and torque gains from 2500 to 6900 rpm are 4 rwhp and 4 rwtq, respectively. How many of you see 6900 rpm in your F-150? Most of the power gains seen were in the 4400 and up RPM range

Flowmaster with an original 40 series showed

269RWHP and 277 RWTQ Gains were seen in the 4200 and up range.

http://www.mustangmonthly.com/techarticles/30401/ Here I found a breakdown of several mufflers, including sound bites. Neither flowmaster nor magnaflow were recommended.. What it comes down to is this:

Everyone is going to have their own preference on a cat back system, and some like one kind others like another. Get what is going to make you happy. There isn't a big difference in hp between diff. systems. Quite frankly, anyone who tells you that got a BIG difference with a catback system doesn't know alot about cars, because 95% of the horsepower available from opening up the exhaust is in the headers and crosspipe (x or H)

 

Nice backpeddle cheif! Classic.

 

golferdude1971,

How about some sound clips and pics of the banks?

 

You can't do headers and X or H pipe without making a lot of noise while it's in use though can you?

 

I got a trailor hitch on mine wors fine

 

It wasn't a backpeddle, it was a "this is turning into a waste of bandwith" I think i'll just stop

 

Well how did they hang the driver's side pipe? You've got magnaflow right?

 

My Magnaflow has a built in "X" pipe in the muffler itself but since I did turn downs at the muffler I added an additional "X" pipe where I cut off the "Y" pipe. It also made the pipes more sturdy. It's extremely quiet in the cab, about the same as stock. I do have the XL size muffler and would recomend the smaller SS version instead. I also have JBA headers. The only noise after she starts that I hear is the mud tires.

 

Wow... I go away for a day or two and miss this great debate! :o

For the record, I finally got a reply from Magnaflow in response to my original question, which was whether or not Magnaflow had a system that allowed dual rear exit behind each tire..

That pretty much decides it for me right there.. Flowmaster it is..
