5.0 exhaust

My 5.0 is quiet unless you are really in it...and even then most of the sound is the whistling from the K and N air filter. I live in VA which means you have to be sneaky about exhaust upgrades. I've considered hollowing out the cats, but I haven't actually done it as I have no idea how loud that will make it. It doesn't have to be ridiculously loud, but I wish I could at least hear it. Any suggestions on how to make a 5.0 sound good, without changing the appearance of the exhaust? Many thanks.

Don't hollow out the cat's.
on a stock system you will not notice the difference in sound, but you will definitely smell the difference.

Most state's only require you to have one muffler, so If you're system has a resonator in the middle and 2 mufflers at the rear just cut off the mufflers and replace them with straight pipe. CLICK HERE for a clip of mufflers cut off.

I've come into this world with nothing and still manage to have some of it left.

cut the rear muffs off, replace them with straight pipe, then replace the resonator with a magnaflow di/do, it has a great sound, especially inside the car, without being too loud

Therein lies the problem, my understanding is that VA has a law that forbids you to alter an exhaust from the way it came from the factory. I even looked into straight pipes once(actually true duals, they said it was impossible) and the guy at the shop said he knew a guy who got a ticket for having TIPS on his exhaust. VA state troopers don't fool around...Laws are more strict in VA, sentencing is more strict in TN. That's all I know.

It all depends on how you have your car, If you have these big flashy tips on your car and have the sound really loud and going around revving your engine, Then they WILL eventually catch you. But if you do it right and have the sound under 92db(I think that is the sound limit) and keep it looking stock, Then they will never know the difference. I'm going to be getting 2-1/2" true duals on mine pretty soon, But I'm not going to go overboard on it, I might get some nice little tips on it, But nothing too big. I've seen ALOT of Ricers around here that sound like chainsaws with big 4-1/2" tips on them and the cops just go right past them...... I hate Ricers..

Sounds similar to the motorcycle situation around here...Harley guys running open pipes seem to be ignored while the ricer guys get busted left and right.

Since Virginia has been mentioned a couple of times, let me point out two Virginia code sections that pertain to this. The first concerns straight pipes, or the total lack of any mufflers or straight thru glass packs, etc.
Quote:
§ 46.2-1047. Muffler cutout, etc., illegal.

It shall be unlawful to sell or offer for sale any (i) muffler without interior baffle plates or other effective muffling device or (ii) gutted muffler, muffler cutout, or straight exhaust. It shall be unlawful for any person to operate on the highways in the Commonwealth a motor vehicle, moped, or motorized skateboard or scooter equipped with a gutted muffler, muffler cutout, or straight exhaust.
And then there is this one concerning how loud. Many of your louder series of Flowmasters, etc. fall in this section. Also, note that chambered pipes are illegal "period" (and have been since GM offered same as optional on select 1967 vehicles).
Quote:
§ 46.2-1049. Exhaust system in good working order.

No person shall drive and no owner of a vehicle shall permit or allow the operation of any such vehicle on a highway unless it is equipped with an exhaust system in good working order and in constant operation to prevent excessive or unusual levels of noise; provided however, that for motor vehicles, such exhaust system shall be of a type installed as standard factory equipment, or comparable to that designed for use on the particular vehicle as standard factory equipment. An exhaust system shall not be deemed to prevent excessive or unusual noise if it permits the escape of noise in excess of that permitted by the standard factory equipment exhaust system of private passenger motor vehicles or trucks of standard make.

The term "exhaust system," as used in this section, means all the parts of a vehicle through which the exhaust passes after leaving the engine block, including mufflers and other sound dissipative devices.

Chambered pipes are not an effective muffling device to prevent excessive or unusual noise, and any vehicle equipped with chambered pipes shall be deemed in violation of this section.
My personal habits are that if loud enough to stop to look, if it has mufflers and the driver drives it correctly, they usually get a simple warning or explaination of the code section. My personal understanding of 1049 is pretty much along the lines of "if it has mufflers and doesn't make more noise than a factory car equipped with louder pipes like a Mustang GT, then I look at it as "OK".

If no mufflers are present, or if it's a vehicle often seen "being horsed around" and it has a louder muffler like a series 40 Flowmaster, or a glass pack, or a chambered pipe ... a ticket is most often the result.

As to the subject of motorcycles, there is this code section:
Quote:
§ 46.2-1050. Mufflers on motorcycles.

It shall be unlawful for any person to operate or cause to be operated any motorcycle not equipped with a muffler or other sound dissipative device in good working order and in constant operation.

No person shall remove or render inoperative, or cause to be removed or rendered inoperative, other than for purposes of maintenance, repair or replacement, any muffler or sound dissipative device on a motorcycle.
Technically, baffles are enough on a motorcycle. I do write straight pipes on occasion where I stop a really loud one and my special wooden stick doesn't find baffles.

I like cars, I understand the desire to have a nice purr to it, and I also understand the desire of people to not have the windows shake when that vehicle is driven through town. I am considering an aftermarket exhaust for my '92 Bird for example. The code section does NOT say it has to "be factory", only of "a type installed as standard factory equipment, or comparable".


Oh yes
, we do write a lot of large tractor trailers and diesel pickups as well. A "turbo" is not a muffler. And I know many officers who just love the sound of a "straight through big mouthed fart can muffler" on a ricer, they love it so well that they most usually stop the driver for an autograph session.

Hope that helps to 'splain it.

A fine pair ... ... and whatever you do, Have a Safe Trip!
