I also have the 14468, it is sheduled to be installed this Wednesday. The shop doing the install has a mandrel bender. An exhaust shop without a mandrel bender is kinda like a dentist without a drill. They are not THAT expensive, and they are a must for high quality installations.

As far as power, I sure hope I don't LOOSE power by installing this muffler! You guys have me concerned now. I am installing it for sound only, and don't expect any gain, but I sure don't want a loss!

I'll let you guys know how is goes Thursday.

Well hope I can find a place here in Atlanta that mandrel bends also. I want my power back.. And by the way, is the 30,000 mile tune up that ford offers for our truck really worth it? they told me for a fuel and intake flush, spark plug change and all the other lube changes, the told me around 500 bucks.. He really danced around giving me a definite amount..Has anyone ever had this done on their L? If so did your truck run any better? i'm at 40,000 miles now and only had my regular oil changes done.. I spit a plug once a couple weeks after i bought my truck..

 

Hey 99Zeus,
How does the truck sound with the Magnaflow?

 

Is the word 'Total' in the name of the shop you're going to. If so, when are you going--I might meet you there.

Dan,
That is the one (on Elberta Rd). I am scheduled to be there at 3:00 this Wednesday. Come on over!

 

Hey 01 Lightning, The magnaflows sound excellent!!! I'm glad i didn't go with anything else. I'm 100 percent impressed with the sound of the muffler. Sounds like a different engine has been planted under the hood. I didn't want a muffler that was too loud. I still also enjoy the whine of the Eaton. So I get the sound of a muscle truck and a Jet taking off at the same time. With the 12468 you get the best of both worlds.. Magnaflow is the way to go!!!

 

99: Have you heard about a bunch(10-20?) Georgia Lightning owners are getting togeather on Jan. 26th at the Silver Dollar Raceway in Reynolds, Ga. for an afternoon(12pm-5pm--it's a Sat.) of b/sing and 1/4 mile racin'? Most are coming from the Atlanta area so you could hook up with them that am and 'convoy' down. If you're interested, call me at 1-800-926-2136 and I'll fill you in. Ask for

Dan

 

whats up old man!!!! j/k i hope u been practicing on that tree thru the winter so u can beat me jan 26th.... hahaha. by the way dan have u got aol instant messenger??????? i simply cant wait for sdr on the 26th.

 

If you keep callin' this ol' man "ol man", I guess I'm gonna have to spank your L come the 26th . I git real close to one of the oak trees in my yard so I can hit one of them pesky squirrels with my single-shot pellet gun that run around about 50' over my head--is that the 'tree' you're talikin' about?

IM is Lightningrod494@aol.com but I'm so lod, I go to bed early....

No problem w/ my magna flo.. Mine wasnt mandrel bent.No more or less power just sounds good...

 

To be honest, I don't think that non-mandrel bent tail pipes will really make a noticable difference in power. That is unless they are really crimped up bad, like to half the size they are supposed to be.

 

Same here.. I have had 4 exhaust systems thus far . I have the stainless magnaflow (no x pipe as it crosses over inside the muffler) Before that i had stock, flowmaster, and another "no name " brand that i was idiot enough to try.

Have you reset the computer ?? Get home from work TAKE THE KEY OUT OF THE IGNITION !!! IMPORTANT!! Disconnect the negative post on the battery. Next morning reconnect the battery and you are off. Just make sure the key is out untill after you reconnect the battery.

This is what was suggested to me and I fell for it. Im not sure if it will help you or not but you may want to clean your air filter at the same time.

Now the computer/sensors are "fresh" to store up data on your systems.

Hope this helps. My magnaflow not only has the ideal sound for me., but i noticed absolutely no change in power. When I had the flowmasters i noticed a HUGE difference in gas mileage (for the better) But they were just too loud inside the cab for a daily driver.

 

Depends on the pipe bender or the equipment he is using. Some bends look almost mandrel quality and and others look like friggin' oragami.

 

I don't think NON-mandrel as oppsed to Mandrel bends are really going to make a noticable differance in a street truck. I think you would only notice the gains/loss on a flow bench not in everyday use. I also don't think that ther are to many mandrel bend shops in the USA not at least a muffler shop the machines are probably a few 100k so I think the big shops have them (KROOKS ect.). I find it far fetched that a local guy has one. I think there must be another problem to give you this loss I remeber someone saying there cat's got messed up this would really kill the exhaust flow and cause some problems not a little crimp in a bend of a exhaust pipe after the muffler. I don't want to flame anyone but lets face it even if you lost 10 hp you would not notice it driving on the street probably the track also.
Hey just my opinion dont kill me...lol

Do a search on your search engine for "Bad exhaust bends" or "Crimped exhaust bends" and you'll find lots of info as to the flow losses involved. Crimped exhaust bends can flow as much as 50% less than a mandrel bend. There is not only a noticeable difference in performance and efficiency, but a great deal of heat retention due to poor flow. This can result in the early failure of the exhaust components. Here are a few links that should give one a basic understanding of what is involved.
