rice pipe?, exhaust Options

[96stgreendemon]

ok, bought an exhaust off my cousins friend today that was for a honda, think he paid 175 for the exhaust. its just the muffler though i was wondering if anyone had put something like this on and could tell me how it sounds.

Hang on to the muffler if you want it and save up a couple hundred bucks and have an exhaust shop make you new 2.25" piping. Welding the muffler to stock piping will make it stupid loud and that's it. No performance gains, no light weight advantages, nothing. You'll be just like every other ricer on a budget.

agree. 2.25" is a good size.

The resonator is key to a smooth tone. Mufflers are good for volume, but resonators are good for avoiding the nasty buzz typical of uneducated car owners (aka pretty much every Civic with a three-inch pipe).

get the vibrant ultra quiet resonator

Only problem is that the Vibrant is not a resonator, it's a round-body straight-through muffler with bad product labelling.

A resonator does not use a "perforated core, surrounded by our premium multi-layer sound absorption materials." A resonator is an echo chamber. It bounces soundwaves into each other in order to cancel them out. The technology is entirely different, despite both items being round metal canisters affixed to an exhaust system. For a demonstration, find a true resonator (if you have the stock exhaust you have one) and tap on it. A resonator will ring like a bell; a straight-through absorbtion muffler will, well, muffle the sound and produce a dull thud.

Obviously, if you reduce the volume of an annoying exhaust note it will stop being annoying, but a resonator will get rid of the annoying note at any volume.

so, are you talking about this?

http://vibrantperformance.com/catalog/prod...;products_id=45

so are you saying this is mislabelled as a resonator?

do you have a first hand experience on this product? have you tapped it personally and have you disected it to see that it has a perforated core?

your words seems a quote from some thread ago...

Yes, that item. I don't have to tap it, the product description which I quoted from the page you linked makes it entirely clear it is not a resonator. Resonators do not absorb sound via insulation, and therefore do not "Feature Vibrant's "True Straight Through" perforated core, surrounded by our premium multi-layer sound absorption materials." Determining that this product is not what it's labelled is as simple as looking at a product description of a "diesel" engine which features iridium spark plugs.

A perforated core surrounded by insulation is the basic description of a straight-through muffler. And the reason my post sounds like a quote is because I've posted it before. The problem is simply one of mislabelling; many people think all round-body items which go into the exhaust system under the car are resonators. They're not.

For a proper explanation of a resonator's function and form, look up Hemholtz resonator.
