So i grabbed a Vibrant flat black 3" about a year ago, the deciding factor was the SS canister and SS packing opposed to other mufflers using fiberglass packing that usually burns out and causes the muffler to get louder.

Well guess what, after only 1100miles the car is getting LOUDER! I am a little disappointed, has this happened to anybody else?

This is on a turbo B series at about 340whp on pump gas 91 octane.

Bump for this one. In for some answers.

I heard lots of good things about them. Not too loud compared to Thermal.
But I have yet to hear reviews on them long-term wise.

Im waiting for my stealth streetpower 3" in/out single muffler in the mail..
$100 shipped through THmotorsports.

no one else?

mine is great no problems

I have a flat black stealth series on mine, 3 inch in and dual tip oulet for that oversize stock muffler look... only like couple hundred miles on it so far and I love it. Nice and quiet, low key looking as well. Full 3" all the way back no resonators or cat.

Sucks yours is getting louder now all of a sudden, hope mine does not. So far so good though.

Not only is it getting louder it was never anywhere near being quiet to begin with

3in flat black on mine, no problems yet probley put 3k on the car this summer still very quite...I love it for interstate driving!

OP: Are you running cat/testpipe/resonators?
If you are running straight piping all the way from the downpipe, it will still be loud.

My streetpower stealth just came in today.
On the side of the box states "Limited 5 Year Warranty", maybe you can contact them.

i love mine sounds like a apexi world sport

3" header back with a 3" resonator in the b pipe, maybe the resonator could be what burned out and increased the noise? Cause it sounds like its just a straight pipe with a muffler.

Thanks for the info about the warrenty

I love my Vibrant muffler. Been on for about a year. Nice and quiet and no issues here

i have probably used the vibrant flat black muffler on 30 different custom exhausts over the last few years. never once have we had any sort of a complaint. i have made 5 differnet K series all motor 3 inch exhausts using that muffler, amd even then there is no noise complaint. there have been 3-4 customers with those exhausts that had a special request to keep the car quiet, and then we use a resonator and everything is good to go.


what kind of tubing are you using on the exhaust its self?

HiProfile

Are you running your car VERy rich? Any muffler will get a little louder after enough soot has permiated the packing, be it fiberglass or stainless. The stainless just won't disintegrate like fiberglass can.

blinx9900

thanks, maybe it is just me resonator that burned out

the piping is stainless steel on the downpipe and the exhaust piping. What kind of resonator are you using on those K's?


no, i have super low compression so i actually run fairly lean, around 12.5-12 a/f iirc, and that using 91 octane.

No probs with my downpipe back setup... It's straight 3" all the way back to the muffler. No cat, had it for about 10 months daily driving. The only probs I have with it is it rattles on the heat shield near the gas tank, but other than that it's awesome

cinci00si

my flat black has been awesome. hopefully mine doesnt kick the bucket

thermal

I've installed a few on customer's car..... never once I heard a complain about it.

We have installed a number of vibrant flat black mufflers. They seem to be a little louder then I'd like them to be on n/a cars, on turbo cars they sound great though because the turbo is acting like a second muffler. The resonator is going to have a lot to do with that raspy sound.

Once I start spooling you won't even hear my vibrant exhaust until right before I shift. It's louder in stop and go rtaffic obviously and quieter when pushing it.

Any other vids of guys using this muffler...curious of the sound.

HiProfile

I don't mean in terms of turbocharged AFRs, I mean overall. Even 12.5:1 will cause soot buildup, especially w/o a cat installed. If you have your O2 disbaled & cat removed, anything richer than 14.5:1 during normal cruise/idle will contribute to soot as well.

blinx9900

Oh i see, i normally cruise around 14.1-14.6 (the gauge kind of goes back and fourth) i use an aem serial data gauge hooked to the aem ems with built in uego to monitor the a/f.

I had a Vibrant 3' on my Integra for a little while, and it turned out to be a lot louder than my old Magnaflow 3" (5x8) muffler.

The very first week the car wasn't too loud, but it got a lot louder eventually so I swapped back to my old Magnaflow.
