B&B triflo vs magnaflow

[jacs]

I'm interested in the finish/fit/sound of the exhausts, as i know both will make about same hp/tq.

 

since i don't know anyone with either on a 5.3 04 truck i'd just like to hear some opinions. How loud compared to stock on idle part throttle full throttle for both of these, and if you can try to describe the sound (hard to do) such as low rumble raspy ect.

I just had a magnaflow w/ custom bent pipe and stainless steel z28 tips installed on my 00 5.3. Idle, sounds beefier than stock, you can tell something has been done to the truck. I can tell you it gets pretty loud on normal acceleration w/ the windows closed, you have to stop the conversation, really resonates in the ext cab, but once od kicks in, you'd think it went back to stock. It's not hollow sounding like flowmasters, not raspy like a glass pack, i think it sounds like a deep C5 vette. When you get on it, man, it sounds really really good. W/ the windows open it just puts a serious smile on your face. I have a wav file of my truck i just made tonight to send out to my friends, I can send it to you if you like along w/ pics of how I had mine routed. magnaflow has some videos on their site, but doesn't give you a good idea of how it sounds inside. If you know about air pressure or db's, I have a meter, can measure how loud it gets on the way to work tomorrow if you want.

no idea on db's..... i'm looking for something that sounds beefier than stock at idle and roars at full throttle..... sounds like magnaflow again.... my old setup on my 99 T/A was hooker long tubes ORY and magnaflow catback sounded awesome, but with a truck i don't want anything that loud.

 

BTW should i buy the catback or just muffler and have a shop bend the pipes, and which muffler / tips recommended (i'm thinking 2 out the back about half way under rear bumper) if anyone has or could point me to some pics it would be appreciated.

I couldn't find anything I liked straight off a catalog page, so I went to a muffler shop I knew did good work and got them to bend it all up. Only thing, the catalog stuff is mandrel bent, so you get a little more flow.

 

as far as dbs go, I'm guessing you were probably hitting 120-140 db in the ta, probably to the point where you didn't want to drive w/ a headache / made people wince. in the truck, w/ stock manifold, stock cats, your looking around 100 db or so.

 

Here's my setup, everyone has em coming straight out the back, I like to do things a little different.

Now that it is a nice setup, Hotwire. Duals out the side will usually be louder than out the back, am I right? I have mine out the back, but I was thinking of changing them to come out the sides instead. I really like those tips. Do you get a lot of dings from rocks hitting your tips?

I really like those tips.  Do you get a lot of dings from rocks hitting your tips?

(sorry to hijack this thread)

lol, not sure, just got it put on Monday.

 

they're stainless steel, but have a black chrome plating, so I'm not sure how long they're going to last although I shouldn't have to worry about them rusting. The plating is really sweet looking, almost looks like glass when you look at them. i have always had tips doing 90s right after the tires, just like that a lot better, keeps from carboning up whatever you're towing too. Last set I had like that were on a 97 s-10, had chrome baloney tube tips that lasted well over 7 years before they rusted from the inside out, they were rock chipped in places, but so was the whole truck. ;)

 

It does make it a little louder in the truck, that way I can annoy passengers, people beside me, etc. keeps people from pacing you and keeping you out of a lane, also sounds good under bridges and concrete barriers.

 

This is how I wanted it done, but they didn't have enough room to tuck it, this was my 89 s-10 w/ a fuel injected lt4 (ran 13.4 in 1/4) I sold due to my new daughter.

Oh god. If its a battle of B&B versus Magnaflow.... B&B TriFlo all the way!! The sound is second only to the Corsa cat-back. Nothing sounds as good as the B&B or Corsa muffs. NO, not even Flowmaster.

YOU ARE NOT HITTING 140db!! I fly a Blackhawk and its about 132db at fly, you arent that loud unless its open headers and even then you only gonna get close at WOT.

FYI.....On the decibel scale, the smallest audible sound (near total silence) is 0 dB. A sound 10 times more powerful is 10 dB. A sound 100 times more powerful than near total silence is 20 dB. A sound 1,000 times more powerful than near total silence is 30 dB. Here are some common sounds and their decibel ratings:

Near total silence - 0 dB

A whisper - 15 dB

Normal conversation - 60 dB

A lawnmower - 90 dB

A car horn - 110 dB

A rock concert or a jet engine - 120 dB

A gunshot or firecracker - 140 dB

You know from your own experience that distance affects the intensity of sound -- if you are far away, the power is greatly diminished. All of the ratings above are taken while standing near the sound.

Any sound above 85 dB can cause hearing loss, and the loss is related both to the power of the sound as well as the length of exposure. You know that you are listening to an 85-dB sound if you have to raise your voice to be heard by somebody else. Eight hours of 90-dB sound can cause damage to your ears; any exposure to 140-dB sound causes immediate damage (and causes actual pain).
