Take just one look at the Porsche 911 991 series and you will find it hard to believe that this is a car built in the modern era. But don’t let its vintage looks fool you; the 991 fosters present-day prowess and YOU can polish it with a few Porsche 911 mods.

Ever since Porsche started producing the very first 911 in 1963, the company has maintained a set of standards. While on the inside the features and specs of their vehicles would go forward, the outside would maintain its old-school appearance. They made few alterations in this regard, but it ended up being what set the 911 apart from other models. But if looks were the only thing that made this car, we’d be forced to ask ourselves why it’s so special that we just won’t shut up about it.

A Lifetime Of Achievements

Porsche 911 Carrera S 991


The Porsche 911 is a sports car. And as one, it does what all sports cars do best. Porsche built this automobile for rallying, racing, and most other forms of competitions that you could think of. Their efforts weren’t all for naught as the 991 quickly became one of the most successful competition cars of all time.

You realize just how much of an impressive reputation the 911 has when you remember that it came fifth in the 1999 poll for Car of the Century. This is also a car that wins us over with a huge nostalgia factor as well, seeing how it’s the spiritual successor of the beloved Beetle. But let’s not dwell on the past anymore. Let’s think of the future. And for the 911, this future is known as the 991 series.

Put in production in 2012, it’s currently the 911’s latest platform. Even though it’s brand new, it stays loyal to the melancholic vintage vibes that every other model preceding it sported. It’s trendy, has a nostalgic allure, and it performs pretty well in a lot of departments. But that doesn’t mean it’s perfect. Owning a car isn’t like owning a math textbook. No one is ever going to take their vehicle for granted.

So, whatever factory specs Porsche had in mind, it might not be what YOU had in mind. Luckily, you can really make your 991, well, YOURS by acquiring some Porsche 911 mods. They’re accessible, affordable, varied, and they will really make your car shine more.

The Truth About Performance

You may not know this (and if you do, kudos) but your 991 isn’t as fast as the experts at Stuttgart intended for it to be. It could have been a conscious choice or it couldn’t have. At the end of the day, it all boils down to the fact that many manufacturers choose to purposely leaving performance tuning out in the open as an option. It does bring a lot of advantages, after all.

We only have one thing to say to you: ECU. Turbochargers are the rocking trend of the decade and that leaves ECU as the reigning king of performance modifications. Are you in a hurry and don’t know how to scout for the right kind of Porsche 911 mods? We have you covered.

Porsche 911 Mods For Exhausts

Exhaust System Porsche 911 Mods


If you don’t give much thought to the sound of your car then you don’t need to worry too much about this part. But since you’re already interested in giving a new edge to your 991, why not go full-in and invest in the way it purrs too? Unfortunately, you can’t do that with the stock exhausts, which are surprisingly tight and restrictive.

Luckily, there are many manufacturers producing Porsche 911 mods for your exhaust system that can help out in that department.

AWE Tuning Porsche 991 Carrera Performance Exhaust

For the example part, we’re going to start with something a bit more particular while simultaneously appeasing the general masses. The Carrera remains one of the most popular styles, so it’s just easier to use the AWE Tuning Porsche 991 Carrera Performance Exhaust as an example.

Luckily, it’s AWE we’re talking about. This is a company with an irrefutable contribution to the world of automobiles and their exhausts in particular are goldmines. Even if you don’t have a Carrera, there are plenty of Porsche 911 mods around to choose from, especially exhaust systems.

Now, this particular mod is most suitable for the 991s that aren’t equipped with the factory electronic exhaust valves. It gives off a boost in sound that’s incredibly audible. But the cherry on top is that it will also give your 991 an impressive gain of +29whp and +33wtq.

Porsche 911 Mods For Intakes

Everything you’re doing so far (if you’re following this order) is leading up to a freed and restriction-free engine. Swapping the factory exhaust for a better, less restrictive one was the salt to this process. But adding in a brand new intake is the pepper.

If you’re not all that familiar with the mechanical processes of your car, all you need to know is that intakes and exhausts are both part of what determines an engine’s practicality. It draws in air and then pushes it to the other side. The efficiency through which it can pull through this process determines whether it’s doing a good job or not.
