24v - Vibrant muffler = Me not happy

Here is the inside of Vibrant's Ultra Quiet resonator.

Regarding your concerns about sound, last i checked, the walls and tubing on a vibrant are very thin and probably lacks any perforation tubing inside the muffler which I know are factors in contributing to loud noise. That said, I'm not sure if adding an additional resonator would make a difference.

I mean the only reason why OEM exhaust systems are so quiet are the thicker casting material in the pipping that pretty much suppresses the exhaust sounds.

grinil, not sure if it will make a difference if you go that route and sound will always be subjective. I'm sure there are members here that don't think a Vibrant is loud enough! lol...

I have an s50 with Raceland long tube to full 3" with a 24" resonator in the middle and a free flow muffler. I'm not a big fan of the sound. I wish I had more growl/throaty ball sound. If I replace my muffler with a different one would that help?

Came for the sound clip, leaving now very very disapointed...

Post sound clips guys with two mufflers inline please!!

Headers>center Borla exhaust>Vibrant exhuast ;)

I have the same setup as Hugo, but I did not ceramic coat the headers. I do get some rasp around 2500-3000 grand, other than that it is glorious.

Order the borla from Amazon

[graphikg]

Any resonator or center muffler suggestions? It would have been nice to know this before hand. Borla might be too pricey - Anything more economical; maybe magnaflow?

[kalib0y]

looks like you want a muffler with chambers instead of flow through packing but I would recommend adding a resonator

[jclar]

Hugo any videos of that exhaust setup you got there?

+1
Have almost exactly that setup set aside for my m50.

You will need another muffler or resonator .

resonator = honda noise, or rather, lack of.

moar resonator, less honduh
As mentioned, you can use a secondary muffler for resonance removal.

S52 headers > magnaflow cat > to vibrant streetpower

That's yer problem right ther.

You need another muffler, preferably in the center. I've got ebay Supersprint headers (ceramic coated, knocked out the rasp), to a Borla ProXS, then back to a Vibrant StreetPower. 2.5" piping all the way from the headers to the back muffler. A resonator is going to do little more than change the overall tone of the exhaust.







If you have to have the cat where you are, have the car tested with it in place, then replace it with a center muffler.

With this setup, I have NO rasp, NO drone at any RPM, it's almost whisper-quiet at idle with just a little rumble, and sounds like I mean fucking business when I stand on it.

[evandael]

sounds like you need a resonator.
