Many of these 3"-5" exhausts the Ricers are slapping onto their cars, besides being obnoxiously loud, are also causing annoying drone and resonance INSIDE their cars. This gets old and tiresome pretty fast.
There is now a fix available http://www.darkicedesigns.c...d=10&url=%2Fshop.php
Makes you wonder why they bothered with the big bore exhaust in the first place  ------------------

So... You put the big exhaust on, usually in increased pipe diamaeter out to the large bore tip, to reduce backpressure and allow your exhaust system to flow better for increased horsepower. That's the idea right?
So... When you get tired of the louder sound... You put this disc in that reduces the exhaust flow by 75%... Thus increasing your back pressure and making all that work to increase horsepower null... Right?

That disc certainly has a small hole in it. Likely back to the stock exhaust pipe size.

I don't know if it's a "ricer" muffler, but I have a 3A Racing stainless muffler on my BMW. Before that it was on an '88 4 cyl. Fiero (on it when I got it). Sounded (sounds) great on both cars. It's throaty, but not real loud & dosen't resonate in the car. They both had (has) the catalytic converter.
The BMW is here, but you can't see the muffler very well. The POS Kodak digital quit, or I would get some better pics of it for you. http://angelonearth.net/BMW.html

This isn't anything new. A lot of 'fart cans' that you buy come with silencers. Probably the reason why you don't see it is that all the guys that buy them just never put them on.

Considering that most Fieros stock now sound pretty loud, it would probably sound pretty bad. Like mixing gurgle exhaust and a Honda with dual exhaust together.

This is correct. They can sound good when done correctly, such as having a full matching exhaust with correct matching resonators. Just bolting a muffler up to exhaust will make it sound bad.IP: Logged |

Not exactly sure what a "ricer" tip is, but I had some concern about my mufflers sounding like buzz cans since they look very similar to what I've seen on small imports that sound like that. I purchased my mufflers from Advance Autoparts, they did not come with silencers but because of the large bore I felt there would be a need so I tracked a set down on Ebay. To my surprise as demonstrated in probably the video before the last, (last linked to below) in my 3900 thread, the silencers made the mufflers sound louder and poorer in quality. As to the over all sound quality I'm very happy with it, the best demo to me is the second run at the beginning of the video; http://videos.streetfire.ne...h-without_680592.htm
You can see the mufflers in my thread which have about a 2.25" straight threw bore. They're pretty tame as far as loudness goes in my oppinion. The rest of the drive after the first to runs was without mufflers.[This message has been edited by Joseph Upson (edited 06-09-2009).] IP: Logged |

When it comes to exhaust pipe diameter, bigger is not necessarily better.
Unless the engine is a gas turbine, the exhaust gases are emitted in pulses. Maintaining the inertia of the exhaust gas flow is essential reducing back pressure.
Intuitively you might think that having one big pipe for each cylinder would give you the least back pressure but you’d be wrong.
A properly designed exhaust system will produce pressure at the exhaust port that is less than atmospheric, this effect being the result of the inertia of the exhaust gases from all of the cylinders.
The effect of these big coffee can mufflers has probably never been dyno’d but I’d be surprised if they provide any power benefit whatsoever. It is more likely that they increase back pressure.IP: Logged |

Now you did it. Confusing the issue with the correct facts about exhaust tuning.
for the record, the super trapp exhaust mufflers/tips use discs and plates to tune the exhaust, they work very nicely when installed and setup properly, but they are not what are put on the ricers.
edit to add the following is a joke:
The correct fix for a fart can is a hose from the end of it into the passenger compartment. that way I might get to sleep at night when they like to road race down the parkway. the sirens are much quieter than the exhausts.
As far as noise in the car, they could never hear it over the 2000w sub woofer systems anyway, so what use is the plate?
