Chances are if you own a Subaru Impreza
and are into mods, you are familiar with GrimmSpeed. Since 2006, GrimmSpeed has
been at the forefront of Subaru exhaust pipes and accessories. The company
started out modest enough, initially showcasing a limited catalog of well-made
steel parts. It didn’t take long for GrimmSpeed’s reputation to grow
considerably once their products started gaining traction. Within the Subaru
community word of mouth spread quickly, especially online. Numerous forums and
message boards became inundated with members talking about the quality of the
parts they were getting from GrimmSpeed and awareness grew from there. Soon,
competitive Impreza drivers were locking in GrimmSpeed downpipes, up pipes, and
other hardware.
Nowadays, GrimmSpeed
stands as one of the leading names in Subaru exhaust upgrades due to their commitment
to standout quality. You will not hear someone say that a GS part is cheaply
made or sports weak welds. Each and every pipe is made, tested, and inspected
before it is ever put in a box to be shipped. Attention to detail is how
GrimmSpeed maintains a loyal following. Take their flanges, for instance. To
them, flanges aren’t just a necessary section of a pipe that has to be
accounted for. Rather, GrimmSpeed uses extra care, thickening up their flanges
to ½” for a tight, uncompromising seal.

When it comes to actual parts,
GrimmSpeed has a lot of them but their main concentration is exhaust pipes. For
Subaru WRX, STI, LGT, and XT owners, there is a wide array of downpipes, up
pipes, and crosspipes to choose from. Bolting in a GS pipe means going for
sturdiness, performance, and quality. All of their products are made and
assembled in the USA using the finest build materials available.

Anytime we’re talking about souping up a
performance exhaust, downpipes are in the conversation. GrimmSpeed knows this
better than anyone, which is why they offer a full line of Subaru downpipes
that deliver in every way. Whether you are looking for catted or catless, supplemental
performance or dynamic horsepower, GrimmSpeed has a downpipe that is perfect
for your setup. Loosen up restrictive exhaust flow with authority!
Constructed of T-304 stainless steel and
mandrel bent for both toughness and precision, GrimmSpeed
downpipes also feature brilliant welds. Now, the company will tell you
that is due to the aerospace-certified welder they have on staff. While that
sounds cool, what it really means is that the welds are not only accurate, but
virtually incorruptible. The importance of this cannot be overstated. One of
the most common complaints about aftermarket down pipes is welding. How someone’s
pipe has cracked welds or fractured after 10,000 miles. Those are both fairly
common stories. GrimmSpeed wants to be known for making the most durable Subaru race exhaust
parts on the planet and it all begins with their downpipes.
Downpipe
Performance
It is really, really hard to pinpoint how much of
a performance benefit any downpipe offers simply because there are too many
variables at play. For example, what other upgrades were on the car when
testing was done? What model year? How are the tires? Are the plugs old? The
list goes on. So if you were to poll ten drivers who have GrimmSpeed downpipes
installed, you may get ten different types of data. But – that doesn’t mean we
can’t come up with estimates, does it? After all, freeing up exhaust with a 3" diameter has to count for something!
You can expect a jump of up to around 20
extra horses when using a GrimmSpeed downpipe. Most claim to get an added 15 HP
or thereabouts. One thing to note is that if you are going for a GrimmSpeed
Subaru downpipe, you will need to tune for it. If you fail to do so you
(likely) will experience boosting issues and other problems. On top of that,
tuning helps you get the absolute most out of the part.
