Went to the muffler shop today. Ended up getting rid of the SI/SO Flowmaster 50series, and went with the DI/DO Magnaflow. I love it! Sounds a little better than the Flowmaster, and throttle response seems to be a little quicker with dual's in and out.

Here are some pic's, and even a movie sound clip if I can get it to work!

Cheap Digital Camera... kind of windy, and the microphone on the camera couldnt handle the loudness of exhaust, but you can hear a few good throttle rev's with out a lot of distortion on some of it.

Im sold... MagnaFlow from hear out!

Enjoy,

Im going to take her for a spin again!

Forgive my ignorance; Does the muffler "act" like the x-pipe?

 

Looks good and love the one wheel squeal

 

Yes, in a way, because both pipes run into the same muffler, it balances out the flow between both the left & right bank.

Atleast, that was my understanding!

I went ahead and replaced the 02 sensors while I was at it! Truck is running great!

 

One Wheel Squeal......... Nahhhh Just wanted a solo for today, 4.10's and LS getting installed next weekend. Then she'll sing "Smoke N & Chirpin" in a duet!

 

You need a new siggy now

 

Nice....Im thinking I need to change mine to a DI/DO and a few other changes.

 

Wow,

We should start making these as a kit.

A comparison to yours and mine:

Hmmm.... I like mine better, cant hear your sound clips so well, Darn Whine coming from your engine.... Sounds like a vacum leak!!


Nice truck Man! Love the SuperCharger, if I'd researched a little more I would have gone with the 5.4 and a super charger, but 04 was the first 5.4 3valve year, and I new the ol 4.6 was tried and true. Just didnt realize they had such a limited aftermarket.


great Minds think alike!

Should of used smaller ID piping. The flow of the engine with your long exhaust pipes losses velocity and cools too fast (hotter the exhaust the 'quiker' flow) and actually causes a performaces decrease regargless what your butt dyno says.

Just FYI. Exhaust matters.

Indeed! You can still go with a turbo setup and you'll be screaming down the road, especially with your config.

These systems are so friggin' long it won't matter what diameter you use. It's not like a Mustang with 10' of piping end to end. We're talking 20' of plumbing.

I hate you. Yours sounds like something out of a Mad Max film.

 

Yea people know when I roll by

 

FX4 Matt - OMG. Just noticed where you are from. Sleepy hollow Ocean City. Our family used to vacation there when I was a kid. Haven't even seen the name for 40 years. I imagine a lot has changed there since the 60's.

The DI/DO works good. I had the Flowmaster 2 1/2" DI/SO to 3" on my 2000 SC. Keeps the stock looking appearance and, as does the DI/DO, eliminates the need for an H, X or Y pipe. My new 2008 Y pipe looks way better in its design than did the older one. Amost looks like a proper 2 into 1 Y pipe. Not sure yet if I'll make any changes soon. So far so good, but always looking for more, right?
