Why go fake? just get a custom job done at a muffler shop it shouldn't cost you too much and you actually gain something not just looks. :thmsup:

No offense but fake=rice :yes:

What will you actually gain besides look? The last thing I know you will lose pressure on your muffler(s).

Just an undocumented wives-tale, not applicable to the average daily driver.

Dude dont get that, its retarded, just put that money aside and got to some muffler shop and ask em for an estamite on a quick custom job, and a gain, you would get a nicer exhaust sound out of it....

I lol'd at the first comment in that link:

"Umm what happens when it's cold and you see smoke only coming out of one of them? In my opinion it's ghetto."

Going to a shop iss a bad idea... I bought a muffler and tip from
Someone here and went to have it welded up just for looks... Didnt even want it hooked up to the exhaust and they wanted to charge me 175 bucks ... Haha no thanks... Went to lowes and picked up some supplies for 20 and did it myself

Next step by a car with dual exhaust lol so you are satisfied.

May want to read this thread for some real daily driver inputs.

http://www.driveaccord.net/forums/showthread.php?t=48828&highlight=dual
And you might want to read this for your own edification:

here is a quote from page 139 of the Australian book
"21st Century Performance"
by Autospeed.com website founder Julian Edgar

begin quote

"Few tests have been done that clearly show the effect of changing back
pressure. Most muffler and exhaust comparison tests change more than one
parameter simultaneously, making the identification of exhaust back pressure
as a culprit difficult. However, Wollongong (Austraila) mechanic Kevin Davis
has done extensive testing of varying back-pressure on a number of performance engines.

These range from turbocharged Subaru Liberty (Legacy) RS flat fours
to full-house traditional pushrod V8s. In not one case has he found any
improvement in any engine performance parameter with increased exhaust back pressure.

The tests came about because Kevin has developed a patented variable-flow
exhaust that uses a butterfly within the exhaust pipe. He initially expected
to use the system to cause some back pressure at low loads 'to help torque.'

However, he soon changed his mind when any increase in back pressure proved to decrease torque on a properly tuned engine. What increasing the back pressure does do is dramatically quieten the exhaust.

One of the engine dyno tests carried out by Kevin was on a modified 351 4V
Cleveland V8. Following the extractors he fitted a huge exhaust that gave a
measured zero back pressure.

Torque peaked at 573Nm (423 ft-lbs) at 4700 rpm,
with power a rousing 329 kW (441 hp) at 6300 rpm. He then dialed-in 1.5 psi
(10.4 kpa) back pressure. As you'll see later, very few exhausts are capable
of delivering such a low back pressure on a road car.

Even with this small amount of back pressure, peak torque dropped by 4 per cent and peak power by 5 per cent. He then changed the exhaust to give 2.5 psi back pressure. Torque and power decreased again, both dropping by 7 per cent over having zero back pressure.

Figure 6.1 {which is a graph with three lines showing HP against rpm** shows
the power curves gained in the tests. These results were achieved on a large
engine with a large overlap cam - one of the type some people suggest is
'supposed' to like back pressure.

If, in fact, power does increase with increased exhaust back pressure, it is
most likely the air/fuel ratio and/or ignition timing that are no longer
optimal for the altered state of engine tune."

End of quote

It has been my experience, that personal anecdotes, and ones own personal "seat-of-the-pants" performance meter, are highly subjective and usually unreliable. The only way for this issue to be resolved to anyones satisfaction, is to obain some base-line numbers on an engine dyno, before any exhaust modifications are done, and then do a followup run on the same dyno preferably on the same day, after any exhaust modifications are done.

Messing with pipe diameters on exhaust headers, could affect the scavaging effect, if back pressure was significantly reduced. However, it is highly unlikely that any effects on backpressure which may occur, AFTER the catalytic converter, will affect the vehicle's performance in a manner in which the on-board computer cannot compensate for.
