RKSport Z28 tips, better sound?

[Red94Camaro]

I thought maybe it would be cool to have the Z28 chrome tips from RKsport. Do any of you think it would make the sound better? I have a Flowmaster 80 series with rolled tips the same size as the stock pipes. Do you think the Z28 tips would do anything? Do any of you have the tips? I remember a while ago someone said they rattled, is that true?

I've got those tips.

here's a note to learn: regular exhaust tips don't change the sound of your exhaust. Only if you add a tip with a resonator will it change the sound. resonators make exhaust smooth out and sound like Rice. You won't keep the nice rumble with your Flowmaster like it is now.

ummmm. I thought that resonated tips helped lower the exaust note. and helped to get rid of the ricy sound. that is why they but resonaters in stock exaust systems, to help quite the sound of the exaust.

there are no resonators in the stock exhaust systems. Resonators are merely fins which the exhaust air enters and is accelerated as the air enters it. Go look at Pacesetter Exhaust tips (Common Rice Exhaust) and I'll bet you $$$$ that There are Resonators built in the Tips. Name a stock exhaust that has resonators built into it?

Technically a resonator is basically a single chambered muffler and is put between the catalytic converter and the muffler in apllications where you can't fit one large muffler at the back to reduce the noise to an acceptable volume. Personally, I can't name a specific application, because I don't know everything there is to know about all the cars in the world that would have to use a resonator. My car has a resonator on it (of course it didn't come from the factory like that)... but not resonated tips. I've never heard a car with resonated tips. All of the ricers I have seen have large diameter thin tips that sound really bad because of the thin construction and short length, and lack of exhaust flow from the small displacement engine. Resonated tips are supposed to dampen the exhaust because they are lined with fiberglass.

Maybe this will help y'all out:

As you can see, it's the Types of Tips Ricers put on their cars. And whaddaya know, Glass Packed Resonators!

Size and length doesn't affect the exhaust note! it's just a piece of metal where the exhaust gasses exit. Resonators change the sound!

Greg, you need to simmer down there buddy.

YES, tips WILL affect sound. Some just more than others. Longer tips that flare out to a larger outlet size will usually create a louder, lower sound, and so on and so forth...

Resonated tips are just supposed smooth out the sound a bit so that you don't get as raspy a sound on some applications.

Racer J,
I'm not flaming. People need to know that tips don't change the exhaust note enough to even tell a difference. 4" long exhaust tip or 8" long exhaust tip will not have a different sound. If the tip has resonators or just some kinda built in fin to circulate the gasses, yes, the sound may change. But taking a straight pipe that might be different lengths won't change the sound. I wonder why my Z28 tips don't sound any different that the 3", 15" long truck tips that some people put on their cars????

[RacerJ]

I dunno, I haven't played around with tips and can't talked from personal experience on this one. I do know that a lot of people on this board have changed tips and found that it made a difference for them.

Personally my situation is this:
Right now: I have the single tailpipe which I made painstaking efforts to cut down to it's out of sight. :cool:
New setup that will be going on: I'm going to be picking up a set of the stainless Z28-style tips from Fast Toys. [img]graemlins/burnout.gif[/img]

And that's just the way it's going to be. [img]tongue.gif[/img]

Why won't it? That's how a musical instrument works, right?

I think it's because they do sound different. Why is it that all of these people with the same engines and with the same muffler types have exhaust notes that are different? Example. I have a 3.8L connected to a Flowmaster 80 and two 3" chrome tips (they are about 15" long, or so)and they have 1/4" thick walls (unlike the tips you see on trucks). My friend has a 3.8L with a Flowmaster 80 muffler... tips are almost the same, except that they are thin (very much like the ones you see on trucks). Ok, let's say you tap my tips with a wooden handle (I'm thinking of the one on the brush I use to clean my car). My tips would go "dong" like a bell... it's actually kind of funny to do that. Do the same thing to my friends tips... definitely not a "resonant" (band nerd term, hehe), basically just get a click. Now, is this not going to affect the sound when the engine is running? I think it will... my car definitely sounds different than his (I'll admit that mine being a 2000 and his being a 99 has a little to do with it). Alright, I agree that this test is skewed because of the change to the manifolds... however, I've listened to many of the different clips, and heard different cars in person. They do not sound identical, similar, but not identical. I'll admit that I haven't heard a car with one pair of tips before and after the tips are changed (which would be ideal)... so if anyone has, step forward and end this discussion. I think I have physics on my side at the moment, so it would be nice to hear some observations that agree or to the contrary.

Dude you have no idea what your talking about again. Please do a search or something. YES most mufflers have resonators in them that is how a muffler works to reduce sound.

Here you go I will help you learn. Even with a pretty picture.

Resonated, angled Baffles in a muffler that is stuffed with fiberglass isn't the same setup as what u find in an exhaust tip

Ok smart guy then why did you say the above? What's your point? I am telling you that you are wrong again. You made a claim that mufflers do not have resonators and in fact they do and yes it is the same technique on a resonated tip.

ok a ford taurus... it has a resonater inbetween the cat and the muffer to help make the exaust quite.

Yes the monza tips do have built in resonaters in them but have you even read the web page for them? <blockquote>quote:</font><hr>MONZA Exhaust Tips with resonators feature glass-packed resonators to reduce even the loudest exhaust note to a pleasing tone<hr></blockquote>

have you ever even looked at an exaust setup on a ricer? hell even pepboys has them on display now look at the tips. Most of them are just big tips with NO resonaters in them. they are usually thin or thick wall rounded tips.

the length of tips will also change the sound. z28 tips will not do $hit because they are very small. try replacing the two pipes that come off of your muffler to a bigger inner dia. and listen to the difference in sound. the only person that is going to convince you otherwise is yourself, try changing out the pipes and the tips and see how much or a difference it makes.

I have the chrome Z28 tips...sound doesnt change except for a tiny little bit. Thats because the way the shape of the tips and the metal creates alittle resonation...but nothing drastic. But they do give a very nice appearance though. [img]graemlins/burnout.gif[/img]
