Perrin Jumpstarts Performance Gains for Subaru Turbo Models

Known throughout the industry for racing exhausts and other engine accessories, Perrin Performance is a name familiar to most car enthusiasts. The company got started some 18 years ago by Adam Taft as a regional outfit in the greater Portland area concentrating on Honda tuning parts. Eventually, Adam realized that the Honda aftermarket was well-stocked by other brands so he moved on to target another automaker popular to tuners – Subaru. Soon after, Jeff Perrin joined the party and the company changed its name.

Since then, Perrin has been a trusted provider of performance exhaust pipes, cold air intakes, shift knobs, bushings, and much more. Basically, if it helps an Impreza WRX/STI or a Scion FR-S get moving, they make it. All of their parts are custom made and known for resiliency. For instance, their line of downpipes and up pipes is recognized not just for improved exhaust flow, but durability, as well. It all comes down to this: if it’s Perrin, the quality can be relied on.


For well over a decade and change, the premier upgrading spot for Subaru turbo models is the exhaust system. It is, almost unanimously, the first area targeted for customization. While plenty of drivers will go for a new catback system, just as many hook up with a Perrin downpipe. The reason is fairly simple. Stock pipes don’t work well. They are not supposed to. Subaru might give you a turbo, but at the end of the day you are driving a car that wasn’t meant for sporty performance. The kicker is that with a few mods here and there, you can have yourself a customized, aggressive racing machine. That’s where a down pipe comes in.
Perrin Downpipe Diagram

A Perrin WRX downpipe can be a powerful weapon. Because the factory setup is laden with narrow tubing and numerous bends, exhaust airflow is choked back. In order to improve the situation you want more width and less bends. Getting rid of the OEM catalytic converters also helps. Although a catalytic converter cleans up the exhaust and filters out some of the fumes, it too, is restrictive.

Perrin designs their down pipes to offer the kind of dramatic increase in airflow you’ve been waiting for. The mandrel bends allow for exhaust to move through with less restriction and since the diameter is wider than an OEM pipe, there is no slowing it down. Turbo spools faster, horsepower is increased, and the next thing you know, your Subaru is making some impressive gains.

Perrin Suspension Upgrades

After you have gone and thrown a slew of performance enhancers inside and outside of your car, the next step is making sure your frame can handle the newfound speed. Often times, it can’t. You’ll notice some shaking, less intuitiveness around turns, wide cornering, you name it. When that’s the issue, finding ways to improve the suspension is a fairly high priority, especially if you’re a competitive racer.

Perrin Strut Brace
Perrin’s line of strut braces (or strut bars, if you prefer) tighten things up for you. Perrin strut bars replace the flimsy, narrow factory braces with brute-tough rigidity. The best part is that there are different types to choose from. You choose by diameter, the higher it is, the tighter the response. And since you are simply replacing a stock part you don’t have to worry about drilling or cutting. Essentially, you are loosening bolts, removing a bar, putting a new Perrin strut bar in its place, and replacing the bolts. It is that simple. You’ll see that your car is hitting turns without losing the angle. Even on drag strips where turning isn’t necessary, you’ll still notice better traction. It’s as if the chassis being given additional support has made your ride into a monster.

Perrin Shifter Bushings
But it doesn’t end with strut bars. Bushings play a large role in the Perrin inventory. Bushings are like pads or cushions. They are found in numerous areas of a car’s chassis and undercarriage and provide support for stability. The transmission in particular, needs an added element of firmness in racing situations. It elevates the car’s response when shifting. Locking down the sub frame promotes better sensitivity. Your feel of the road improves and so does your performance.

Perrin has a wide variety of polyurethane and other bushings available. They have different durometers, depending on what your specific needs are. If you’re a serious driver, this is one category of products you might not want to ignore.

The Perrin Way

The bottom line is that Perrin Performance showcases a full array of accessories meant to give your Subaru or Scion an advantage on the road. Even if you are not the kind of driver who tears it up on the racetrack when the weekends come, there are still plenty of choices available that help give your ride a healthier profile.

UltraRev carries the widest selection of Perrin automotive accessories you’ll find on the net. Downpipes, strut bars, up pipes, bushings, intakes...the list goes on and on. In addition, we offer the most competitive prices around. If you’re scouring the market for that next great upgrade hop on by our inventory. You won’t be disappointed.

Subaru Owners Know GrimmSpeed Downpipes Are Built to Impress


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.
GrimmSpeed Downpipe

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.

GrimmSpeed Downpipes

GrimmSpeed Catted Downpipe
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.
