Re: ***** exhaust

Well being an exhaust system is designed to fit a certain vehicle i would stick to a system that fits. Unless you would like to fab hangers bend pipe and be a pita.

Re: ***** exhaust

I think you would have a lot less hassles and less money just buying a cat-back system that was designed for ur camaro, just my opinion.

Re: ***** exhaust

Go for it. Make sure you get a sound clip or a video of it after you put it on.

I always wondered what it would sound like, but I still haven't seen one.

Re: ***** exhaust

I've seen the stock, dual tipped exhaust built with mufflers like that, here on TGO,so it wouldn't be the first time. Just never heard how it sounded.

But I think it was built with "V8 style bullet" mufflers made for dual exhaust & not just using 2 4-cyl r i c e r mufflers.

Re: ***** exhaust

I wasn't referring to duals. The stock single pipe splits into 2 outlets at the rear. That is where they put the 2 mufflers at.

Sorta. That is a 4 liter v8, so an SBC would probably sound deeper.

Maybe look at something made for a Supra. They are about the same length as an fbody, and put down 4th gen power so they probably flow pretty well.

I don't think you get what I mean.....

INSTEAD of the muffler even being there, use that area as the splitting point, then put dul mufflers AFTER that.

Like my rear section is. I just have a single bullet muffler before the rear axle.

Re: ***** exhaust

I put a japanese muffler on my saab. It was loud and didn't sounds very good, kinda raspy. Swapped it for a magnaflow and it's much quieter and smoother sounding.

Do what you want, it's your car.

Hmmmm.....I guess that Dodge Vipers qualify as rice then, since the first ones out had mufflers with twin tips, at the very rear of the bumper!

WTF are you talking about vipers and tips for?

I was talking about aftermarket mufflers/systems that every honda civic owns that this kid wants to stick on a real car.

Re: ***** exhaust

i think the "r!cer" exhausts your talking about are going to be too small in diameter for your V8, you need at least a 3" single really for these cars, 2.5" might be ok, but not if you want to make any real power

Then save your money and buy a real exhaust. I agree that our cars need at least 3 inch single, I think most of the r i c e r pipes are 2 inches.

Easy.....You said ricers have mufflers with tip. Since Vipers have mufflers with tip, they must fall in to your description.

I guess my Corvette is a ***** too.. And so are all other c3 and c4's


Anyway, to the OP. If the car is a huge POS whatever, You will be just adding to a horrible stigma and sterotype these cars have, and one that alot of members on here are trying to obsolve by building and restoring proper Thirdgens. If its a decent car. Dont mess it up with some J/A honda type exhaust system. Its just stupid. and any motorhead/car guy with half a brain will say the same when they see you driving around in it. All IMO of course.

Re: ***** exhaust

It will probably sound close to a glasspack thats essentially all those jdm type mufflers really are. look into companies like hks , apex. Aside from the hole ri*e thing i think that visually that style muffler just won't fit well enough to look good. just my 2 cents

x2, they're just glasspacks with larger chambers and the option of a silencer (on some). When it comes to muffler technology they're pretty much back in the 70's but with oversize chrome tips.


a propper muffler would sound better and last much longer, or just straightpipe it with a pair of long 3.5" diameter tips.. http://cgi.ebay.com/ebaymotors/STAIN...Q5fAccessories

Re: ***** exhaust

Well what you have to understand is that what gives those cars their distinct sound is the fact that they're 4 cylinder cars.

Your car is a v8 correct? So at idle your motor will be spinning at ~800 rpm, so you are firing 400 times a minute, divided by 8 cylinders firing each time. So each cylinder fires 50 times a minute, divided by 60, reducing it to 0.8 fires each second, almost one cylinder fire each second.

Opposed to 400 times a minute divided by 4 cylinders, with each cylinder firing at 100 times a minute, divided by 60, reducing to 1.6 fires per second.

So what I am getting at is that due to the lower rate of fire in our V8 powered cars, we cannot really attain the same "fart can" sound that those cars are so famous for.

In my opinion, I think it would just sound raspy, like the other posters say, like a glasspack.

Anyone feel free to correct me if they feel I'm in any way incorrect.

WOW, your understanding of an internal combustion engine is all jacked up. I'm no brain scientist but how can the 4cil have twice as many combustions per minute as a v8 at the same rpm? Does that mean i can pull four sparkplug wires and start having twice as many combustions per minute?

No, all that would do is create more time between combustions.

You have to understand that the RPM does not reflect the amount of times a cylinder fires per minute. RPM is each revolution of the crank.

In an internal combustion engine there is only one stroke of a four stroke cycle that creates power, if there was no flywheel on the engine (to balance the difference between power and intake/compression/and exhaust strokes) the single power stroke would not be sufficient to spin the crank efficiently.

As a result we just added more cylinders to do all that work, multiple times over.

So with the understanding of that I'll move on. A V8 needs less firings of it's cylinders to spin the crankshaft the same number of times as a 4 cylinder engine. Understand? In order to spin the engine at 800 RPM a V8 is not firing it's cylinders as many times as a 4 cylinder engine.

I believe somewhere around V12 engines is where engines have almost 360 degrees of power stroke rotation.

Do you understand what I was saying?

Now we get into torque vs horsepower. Because V8 has twice as many cylinders firing, it gets the engine spinning much quicker than a 4 cylinder engine, which is why V8's have so much torque.

Now on the opposite side, this big and heavy V8 has so much rotational mass that it does not safely spin at such high RPM's as a 4 cylinder engine, which is why 4 cylinder engines make their horse power in high RPM's.

Hopefully this helps.

Re: ***** exhaust

I stand by my origional statement. You have no idea what you are talking about. The number of cylinders doesn't matter. Each one fires the same number of times at a given rpm. Doesn't matter if it has 3, 4, 5, 6, 8, 12 or even 543.

That's one of the most ignorant auto-related things I've ever heard.

Take a couple of auto classes and come back.

Re: ***** exhaust

So, if according to you, every engine fires each cylinder the same amount of times at each RPM why is it that you can sit there at idle in a V8 and count the cylinder fires?

Good luck trying to do that at idle in a four banger.

Re: ***** exhaust

there's alot more to exhaust sound than just number of cylinders and mufflers, displacement and volumetric efficiency play a huge role in tone and sound. there's also things to consider, like the firing order headers or manifolds, primary and exhaust size, primary and exhaust length, do I even have to bring up idle rpm?

a 4 cylinder and a V8 of similar cylinder volume and volumetric efficiency, Idling at the exact same rpm, the V8 will have a smoother Idle, because it has powerstrokes every 90* of crank rotation, where as a 4 cylinder has a powerstroke every 180*.

Re: ***** exhaust

and, as I said before, save your money anddo it right once, If you can't afford to do it right the first time, can you afford to do it again?

We are both talking about four stroke engines correct? In a four stroke engine the plug fires once every four strokes, since there is two strokes to every one revolution of the crankshaft then the cylinder combusts one time for every two revolutions of the crank. No matter how many cylinders the engine has, this one always repeats this same action. If it didn't then it wouldn't be a four stroke. I don't know how i can make it any more simple than that.
If you think you can count how many times a cylinder fires... Then that's another WOW.

You have to understand that the RPM does not reflect the amount of times a cylinder fires per minute. RPM is each revolution of the crank.

In an internal combustion engine there is only one stroke of a four stroke cycle that creates power, if there was no flywheel on the engine (to balance the difference between power and intake/compression/and exhaust strokes) the single power stroke would not be sufficient to spin the crank efficiently.

As a result we just added more cylinders to do all that work, multiple times over.

So with the understanding of that I'll move on. A V8 needs less firings of it's cylinders to spin the crankshaft the same number of times as a 4 cylinder engine. Understand? In order to spin the engine at 800 RPM a V8 is not firing it's cylinders as many times as a 4 cylinder engine.

I believe somewhere around V12 engines is where engines have almost 360 degrees of power stroke rotation.

Do you understand what I was saying?

Now we get into torque vs horsepower. Because V8 has twice as many cylinders firing, it gets the engine spinning much quicker than a 4 cylinder engine, which is why V8's have so much torque.

Now on the opposite side, this big and heavy V8 has so much rotational mass that it does not safely spin at such high RPM's as a 4 cylinder engine, which is why 4 cylinder engines make their horse power in high RPM's.

Hopefully this helps.
I think with this statement,,,u should not be working on any engine,,,even if its a lawnmower !!!
Tourge is made because of CI and not on how many cylinders u have, also a 4 cylinder revs up faster then a V8 because of less weight on the internals...think about it for a minute before u say anything !!!!!!

Fail. A four-stroke engine fires one time, per cylinder, per two revolutions. So a single cylinder engine at 600rpm fires 300 times per minute. Divide 300 ignitions in a minute by 60 seconds per minute and you get 5 times per second. Multiply that by eight cylinders and you get 40 total ignition events per second. At 600 rpm idle. The "lumpy" sound that's almost slow enough to count is one cylinder making a bit more noise on the exhaust cycle than the other seven. Four cylinder engines typically run smoother and quieter, and idle faster.

What do you mean smoother? newer ones have balance shafts to smooth the INHERENT imbalance of a I4 engine, how many v8's do you know of that have balance shafts? The closer the ignition events are together(8vs4) the smoother the engine will idle,accelerate,etc.

This isn't for you el_muerte.
A v8 has more IGNITION events per engine rotation plain and simple all cylinders HAVE to fire every other time it comes to TDC which is every 720*s. A v8 will have TWICE as many ignition events at a given rpm as compared to the 4cyl.

I can explain it to you but I can not understand it for you.
