Was at a shop today.
He doesnt do Mandrel pipe and said he doesnt know anybody that does thats not 90 miles
away.
Quoted FloPro 22inch muffler $375.00 + whatever I pick for tips. Dual out the sides.
3 inch in to 2-2 1/2 inch pipes coming out.
Magnaflow 24 inch muffler $405.00 + whatever I pick for tips. Dual out the sides.
3 inch in to 2-2 1/2 inch pipes coming out.
Said could also do a magnaflow round body muffler for a few dollars difference.
Said he would do Alumnized pipe and do the bends for the exits anyway I wanted.

Dont know what the tips would run on top of this, but it seems high considering I think the cheapest MBRP dual out kit I found was around 470 shipped. And that would be stainless.


Found this on the Flo Pro it doesnt sound to bad..

Do you guys remember the Ford F150 FTX Tuscany that was sold at one time. Think it was a aftermarket kit. Anyway I remember the exhaust on that truck sounding like what im looking for but I dont know what muffler they used on it.

 

There's many people on here that say a 3 1/2 exhaust on the 5.4 3v is too big. That you will lose low end. The thing is those saying that don't have this exhaust on their truck. Pimp had a dyno run and claimed torque gain everywhere but most significant improvement was at 3500 rmp? If I remember right and I don't feel like searching for it. I wish he would have, or would, scan his dyno run and post the results. I've called and emailed MBRP several times now requesting results. They tell me I'm on the list when they get it. In other words I probably shouldn't hold my breath. As I've said before, I didn't feel any loss down low. That's strictly just MY feel. Take that for what's it worth since you don't know me from Adam.

If I were you and after seeing those quotes I would order either the MBRP SI/DO XP $432 shipped or the SI/SO $345 shipped. All stainless systems and you have the satisfaction of installing it yourself. Those prices are from truckcustomizers.com

I have not idea if this will work or not. Hopefully someone will respond that knows. If you order the SI/SO and think it's too loud in the cab or you think you lost low end torque, you could always try replacing the 3.5 mid pipe with stock sizing from the cat back to the muffler (36"). And then see if that helps either problem. That would be the only aluminized.

 

[QUOTE=mxracer49;3569411]Yeah the guy at the shop said that if you go to big you start moving your torque curve higher up the band. He suggested staying with 2.5 but then when you think about it, If I go dual and they are 2.5 each thats 5 inches vs the 3 1/2 for the single.

Whats the XP version?

Thanks for the input

 

Here is a Roush kit that is side exit.

They make a Pro XP and Installer series. mbrp.com

 

Started figuring that out before you posted this,
Pro = Best
Xp = Better
Installer = Good

Hey can you do me a favor and head over to
http://www.flowmastermufflers.com/sound.html
And click on the sound clip buttons for each and tell me which Flowmaster you think sounds the most like the MBRP. I think these sound clips give you a better feel then then the ones on YouTube.

 

Different grades of Stainless on the Pro and XP and Installer is Aluminized.

The SI/SO sounds really close to the 50 Series Big Block.

Here's mine at start up and drive off from a REALLY cheap video camera that records to SD cards my daughter took. http://www.youtube.com/watch?v=SE2cs...eature=related

Also this one. http://www.youtube.com/watch?v=NLqEh...eature=related

I switched the overdrive off halfway through that video. That gives you a pretty good idea what it sounds like. Try to pick out the other sounds besides concentrating on the exhaust. Like the road noise. You're familiar with how loud the road noise is. And then compare that to the exhaust.

I'm pretty sure the guys on here that have this exhaust all agree it's a very deep rumble. But it's a "clean" rumble. If that makes any sense at all. Hell it's 3 1/2" it should be low. For exaggeration, think about the difference in tone from a trumpet to a tuba.

 

I had a Flo Pro DI/DO on my Silverado, was decent, not well toned though.

I would not pay for those prices, especially for non mandrel bent piping, aluminized, and SI/DO configuration. I vote find a new shop, or buy a cat-back.

I would say the Super 40 would sound the most like an MBRP. Having heard nearly every Flowmaster in person, and by HD videos online, the Super 40 is the deepest noted and calmest 40 series line of mufflers. The Super 44 is deep too but really loud.

 

MXRacer says 50 series big block,
Darren says 40 series,
Thats a spread in comparison with the flowmaster...I actually think I like the sound of the 50 series SUV.
MXRacer, it actually sounds like its droning quite a bit to me? until you take the OD off.

I agree with the finding a new shop or just getting a kit. What do you think a set of tips would have cost me? 40 a piece?? so 375.00 + 80.00 = 455.00
After doing a little shopping around on the internet. I can get Full blown stainless for almost the same money or less depending on which way I go.
Question is Dual or Single
Will the dual create more noise?
Will the dual create less low end torque since im pumping exhaust out 5 inches of pipe vs 3 1/2 inches of pipe with the single

 

$35 - $50 per tip is average for good stainless tips, $40 sounds just right if you can get the deal.

Dual tailpipes will be a little louder, no it wont affect your torque. You will be fine.

pumping exhaust out 5"s? what does that mean?

 

Oh yeah, you can hear it. That's why I bought an aftermarket exhaust. So I could hear it. People want loud but not too loud. "I want to hear it but I don't want to hear it in the cab". A drone? I dunno. If you lug the motor it drones at a certain frequency. But I rarely drive with the rpms below 1100 or so. I keep OD off a majority of the time. I haven't done alot of highway driving with this truck yet. That will come in the spring when racing starts. If you want aftermarket exhaust you're going to hear it in the cab. If you say you can't hear it in the cab? I call BS. Unless you have the cab deadened.

I can carry on a conversation with my wife while going down the road and it doesn't interrupt us. And when her and the kids aren't with me, I can't hear it because my stereo is too loud.

 

2 - 2 1/2 inch pipes (dual) equal 5inches of exhaust pipe compared to the single outlet of only 3 1/2. So less torque with dual? at least at a lower rpm?

 

Actually I noticed that the in cab video that you did. The sound is louder when you are focused in on the speedo. When the camera is in the center of the truck and looking out the front window its not so loud.
Dont know if this is when you had the OD off or if you were of the gas or if its just because of holding the camera in a different location.
The "carry on a conversation" note helps, as I thought it would be to loud for that.

 

Anybody...

 

No thats not how it works, if your running a 3" inlet to a 2.5" dual out the velocity levels out and flows healthy. An all 3" system would be better for the performance so velocity will always remain, but tailpipes dont hurt power that much.
