People buy aftermarket or custom BMW exhausts for any number
of reasons. Some for the sound, others for the name. However, most people
aren’t aware that they should examine more than just one or two features of the
exhaust they’re looking to purchase. That’s why I’ve compiled these seven
important features to use when comparing exhaust options.
Improved Performance
There is no point in scrapping the restrictive, factory BMW
exhaust for something custom or aftermarket if performance isn’t improved upon.
That is why it is wise to shop around for exhausts that will enhance horsepower
and torque numbers as much as possible.
Better Exhaust Flow
Generally speaking, the better and exhaust flows – the more
performance can be improved upon. Granted there are situations where an exhaust
can flow too well, causing the BMW to run less efficiently and starving for
power. When it comes to exhaust flow, it’s best to find something that is
larger than the factory exhaust, yet not so big that a small animal can crawl
up there.
Sound Quality
Everyone has their own taste when it comes to exhausts.
However, it is important to remember that it’s probably not a good idea to
purchase an exhaust that will immediately notify the entire neighborhood every
time the car is started because it’s so loud. Deciding on an exhaust that is
nice and quiet at idle is only half the battle. It needs to have the potential
to make your ears “gasm” at the top of the power band.
Drivability
Sometimes an exhaust may sound exceptional at idle, but once
it’s opened up it may have a really annoying drone that seems to linger with
you for the rest of the day. This is why it is important to check buyer reviews
to see if they have experienced this “droning” noise that can drive a sane man
mad.
Installation Difficulty Level
If the exhaust you have your mind set on can’t be installed
without the use of a saw, welder and some experience…keep searching for
something more suitable to your skill level.
Appearance
Let’s be honest, more people buy an exhaust for the sound
rather than the looks – but I’m not here to judge. If it looks half as good as
it sounds, you’re on the right track to find that BMW exhaust you’ve been
looking for.
Price
Unfortunately, when all is said and done, none of the above
features matter if the price of the exhaust rivals how much Floyd Mayweather
makes in just one round of a boxing match. The perfect BMW exhaust is one that
is a collaboration of everything that has been mentioned, with a reasonable
price to match.
