Exhaust tips: improved sound?

Sykotik · 24-01-2007, 02:24 AM

Sup all?

I'm considering installing an exhaust tip on my car and I just wanted to know if there is any difference in the sound of the vehicle? I want a deeper sound than I have now and really don't want to go out and get myself a new exhaust system due to the fact my current one is in perfect working order and that I am on a budget.

I have a 1985 Ford Meteor GC2 Ghia (1.6 litre 4 cyl.) and it has a 1.25" exhaust on it. Still stock I think it is. Just got the muffler replaced which is another reason for me not to get a new exhaust system.

Sorry mate, you will not get any improvement, the only way the sound can increase is by increasing the size of the piping. Tips are just for looks.
If you wanna put a dumpy on the end, meaning the tip bends on an angle towards the ground. That might make a very small gain but not worth it.

As said tips do nothing.
Cannon mufflers change note, but not performance.

a set of second hand extractors with a 2" pipe shouldnt set you back a whole lot and makes for some fun noise

Sykotik · 24-01-2007, 11:45 AM

ahk, sweet thanks for all your input.

io must dissagree with some of what you have said... i got a 2.5" system on my EF and it was really drony then i put a lukey tip on which als had a restonator innit and made it elss droney and a lil more barkey... depends on tip i suppose

bigger system wouldnt hurt either methinks

had a 2.5" lukey stainless with resonator, and mini-muffler with headers on my 13B RX-7 also no converter. god damn was that thing loud.

my dad's XR8 has a Herrod Cat back system in it. anyway, after we took off the standard 2.5" twin tips with baffles in them, and put some some big **** off tips, the note got a little louder, and its a bit more droney :P

It changes the way the exhaust note resonates into the open air.... so more, tone/note as opposed to the overall sound. But with a std exhaust system, there's not much noise in the first place... and therefore you prob wont even notice a change.

With a modified exhaust, that's actually making some noise, there's a lot of different sounds you can produce by varying the tip.

adding a tip is not automatically adding a resonator. that seems to be the difference between what sykotik asked and what mutha suggested

When I installed a 2 1/4 inch cat-back on back2thefutura's 2.0 Focus, it was a pretty flat sound, until we added on the 3 inch rolled chrome tip, which gave it a much rounder, more polished note. Wasn't a massive difference but it was still noticeable whilst driving.

Sykotik · 25-01-2007, 12:15 AM

Wouldn't the vibrations of the pipe echo in the exhaust tip, thus making it louder?

Only if your exhaust isn't attached to the car and the heavy tip makes it touch the ground.

Bending the the tip at an angle makes a small gain in what, noise or kws?

on who's car? :hihi:

yes it did make a bit of difference to the sound. the biggest thing that made a difference to the sound of it though was when it was driving off with it's new owner. sounded great that day.

In noise, the sound resinats off the road instead of straight into the atmosphere. It's only slightly louder.

my last car anef with a 2.5 cat back originally had a tin can tip (i know flame me) was really drony until i had the double d tips put on instead and it made it more throatier but didn't really increase power

depends on teh tip fitted...
some tips are just a lain stainless/mild steel tip others
can have resonators in then... my tip was aroudnd the $70 mark as it had a resonator..

i prefer a nice note than alotta noise, hard to get from a 6banger

4.9 EF Futura · 25-01-2007, 11:39 AM

No, i wouldnt expect change in power... or a noticeable change in volume...

But the overall sound/tone/note of the exhaust will be influenced by the shape, size, configuration and material of the tip.

Ryan · 25-01-2007, 11:45 AM

When I put the dump tip on the VL (Replacing the "Cough* Cannon) it gave a nicer note, but it didn't really make it louder.

Slightly off topic.

Does anyone hate ridculousy loud exhausts on slow cars? My mate had a N/A VL Auto, with a very loud exhaust. It was the slowest, biggest POS ever.

Just had the exhaust fixed on my daily driver this morning... driving home from work last thursday and the heat/vibrations got the better of it... engine pipe broke clean just underneath headers.

18R-C engine dumping straight out of the headers on the way to the exhaust shop this morning - a great start to the day.

And being an RA40 celica, not the quickest thing on 4 wheels lol.

Hybrid34 · 25-01-2007, 10:07 PM

take all the resignators out will improve sound

Sykotik · 26-01-2007, 04:01 PM

Wouldn't removing the resonators mean that my car wouldn't pass emission standards?

Sykotik · 29-01-2007, 02:44 PM

Yeah, just an update. I bought the exhaust tip. 1 and 6/8 of an inch and slapped it on. The sound, generally sounds the same when the car is idling however a difference in sound can be heard when the accelerator is pumped. It's a little throatier than before. Just need to get it welded on and all shall be good.

red_hotxr6 · 29-01-2007, 03:58 PM

Why does it have to be welded, cant you just fit it to the end of the exhaust.

nat_daly · 29-01-2007, 04:00 PM

answer is no

Laminge · 29-01-2007, 05:12 PM

One of the best threads on the forums for a good laugh for ages.. thanks

**aussiblue** · 29-01-2007, 07:07 PM

Double walled and semi resonator tips certainly can effect the exhaust sound see

The shape and construction of the exhaust tips affect the overall tone of the exhaust note, and can affect exhaust flow as well.

Exhaust tips actually do play a role in the final sound of an exhaust. Where mufflers and resonators take care of the good majority of exhaust pulse cancellation and silencing, the exhaust tip can shape the remaining pulses and accompanying sound as it makes its final exit from the pipe. Much in the same way a Tuba sounds different than a Trumpet, a short megaphone exhaust tip will sound completely different than a long pencil-shaped exhaust tip. Some exhaust tips even add a small resonator to the equation to help mellow and deepen the exiting exhaust note. A perforated tube surrounded by sound deadening material puts one last mellowing touch on the exhaust pulses before they reach your ears and the ears of others.

Mounting can also have an effect on sound. A tip that is mounted with a compression clamp or welded on can provide a more solid sound than screw-on type tips. Screw-on tips mount in the same way a light bulb cover bolts onto the ceiling light fixture. Three bolts or screws hold the tip onto the end of the exhaust pipe. Finally, while claims of exhaust tips by themselves adding horsepower are numerous, these claims should be approached with great skepticism. Unless the tip being replaced is acting as a massive restriction to exhaust flow, replacing an exhaust tip is more an exercise in style and sound than noticeable horsepower gains.

or just do a google search on "exhaust tip effect on sound" for further verification.

and those like me who were around in the 70's will remember the infamous rat trap exhaust tip that made your 6 pot Torana sound like a V8............ until they were legislated off the road.

You could however by simply sticking it on, the exhaust isn't secure. Doesn't really look good when your driving down the highway and your exhaust tip flings off.
