hooker aero chamber mufflers
anyone have any experiance with these? i know they flow awesome but im wondering how loud they are? comparable to a perforated core of the same length?
or are they more along the lines of a turbo muffler?
im thinking of installing one on my 05 f-150 with single 3" exhaust, i dont want a straight through perforated core muffler like a magnaflow or glasspack
either a dynomax super turbo or the hooker aero chamber
any one have any experiance with the hooker?

Hooker Aero Chambers will flow 145 cfm @ 5" on 2 1/2" mufflers, they will knock down the noise as your into 3" that may bark.
Check into Edelbrock's RPM series, they are a flow thru but may drone if you have a large pipe and larger tips.
Spintech--------------------165 cfm ( I replaced RPM's with these, very happy with less drone)
Hooker Aero---------------145 cfm
Dynomax Turbo-----------135 cfm
FlowMaster 40 series----115 cfm
FlowMaster 50 series-----90 cfm

thanks for the response, just curious where the data came from?
how do the spintechs compare to flowmasters in the resonance department?
ive heard spintech before on the trail and they sound awesome

its not a huge deal, im just curous because i have seen some specs from places like dynomax and flowmaster, they tend to be biased....i prefer the ones that are done independantly
that being said, usually if the muffler are within 20-30 cfm of each other its negligable

Different testing companies test at different inches of water, some at 5, 15 and 20 inches wc.
Check into www.broaderperformance.com, under their muffler flow chart.

Sorry I can't post other muffler information as I was warned by someone in the FTE who can not be notified as they have a block to reply (chicken you know what) if I do it will be my last post. Seems I went thru their "filter" system on posting helpful information for you and other FTE members and this isn't for personal or financial gain just helping other FTE members. This has become a hear say not help with facts or information forum.

yea its cool, that happens to me all the time on here as well, thanks for trying!
whats the difference in all the inches of water flow testing? like what would be the differences in 10 and 15?

At one atmosphere your at 14.695 psi or 27.677 inches water. 1 psi is 1.883 inches wc (water cold). 10 inches wc is 5.31 psi below atmospheric or vacuum, 15 inches wc is 7.96 psi below atmopheric or vacuum. Between the two is 5 inches wc or 2.65 psi vacuum.
Different muffler manufactures use different pressures (vacuum) to rate their mufflers hence higher cfm numbers that fool the general public.
Seems there isn't a set standard pressure (vacuum) that all muffler manufactures go by, buyer beware. You must also remember cfm numbers and the speed of sound change with the higher temperatures inside a exhaust system.

i wish there was a way to getr all manufacters to agree on a set flow test and sell their muffler with a flow rating and decibel rating as well as the pipe size, that would be awesome

Even my muffler shop owner friend shakes his head when customers come in with these super flow numbers and tell him he's wrong while they have a paper with numbers they don't understand. Out comes his book with different flow and pressure numbers. It would be hard to make a Db standard for different mufflers as there are too many variables, one muffler that is quiet on a test motor could be louder than a loud muffler because of a different cam and compression on your motor. A friend heard mufflers on a BBC that he liked, installed on his 440 Dodge powered PU sounded totally different and crappy.
I guess you get lucky once in a while and fail at times?
Run 2 chamber FlowMasters and be a equal opportunity offender.

I have a hooker aero chamber on my 93 f150 w/5.0. I put a high flow cat on it and it sounds good idling and I can't really hear it when I am driving at highway speeds. I was thinking it would be louder, but really I am happy with the idle sound and quieter at driving speeds. Nice muffler, would use it again.
