Lexus 3IS: Aftermarket Exhaust Modifications
If you are looking for a way to make your third generation Lexus IS a bit more feisty, read on.
This article applies to the Lexus IS (2014-2015)
Changing the exhaust is the most effective way to change the sound of your new Lexus IS. Depending on the system, some horsepower and torque power gains will be small due to the lack of tuning support on these cars. When purchasing a new exhaust, the most important consideration is to listen to it first. Even if it has ugly exhaust tips, choose the one that sounds best to your ears. Tips can be changed, but it's a lot harder to alter the sound of something you don't like.

F Sport Factory Exhaust
Price - $900-2,000
Style - Axle back with single tips
Install Type - Modification needed
Due to its notable sound and its clean styling, this exhaust is a favorite pick. The sound is as close to a V8 as you can get with minimal drone inside the cabin. Since this exhaust comes on an F Sport trim Lexus, there might be used exhausts for a bit cheaper than a new one. Lexus IS models built before 2013 will have to be modified in order to accept an F Sport exhaust.

Magnaflow Axle Back
Price - $1,300
Style - Axle back with single tips
Install Type - Bolt-on
The Magnaflow axle back is very similar to the F Sport factory exhaust. The two look and sound very similar. The Magnaflow is the perfect substitute for those who want the F Sport sound and look, but in a bolt-on package. Install time is approximately 1-2 hours with the proper tools and work area to get under the car, so this is a good choice for the weekend warrior.

ARK Performance Exhaust
Price - $1,700
Style - Cat back with single tips
Install Type - Bolt-on
This exhaust is one of the loudest on our list, but it's also best sounding. The sound has the capability to set off your neighbors' car alarms on cold starts. Depending on where you live and how much you like your neighbors, the ARK system might be the right choice. This exhaust is "cat back," which means it replaces everything from the catalytic converter and back, allowing for the greatest power gain and the most noise change. Recommended for anyone looking for a loud, but good sounding system.

HKS Hi-Power
Price - $700
Style - Cat back with single tips
Install Type - Bolt-on
HKS makes the perfect kit for those on a budget, but still want to improve the sound of their car. The sound is louder and higher pitched than the Magnaflow or the ARK Performance kit. From a sound standpoint, it's about the same as the L-Tuned exhaust or a TRD axle back. The key difference is this one is readily available in the U.S. market.

Invidia Mid-Pipe
Price - $400
Style - Mid-pipe
Install Type - Bolt-on
From the catalytic converter to the start of the axle back exhaust, the Invidia Mid-pipe kit replaces everything your cat back doesn't. This system can be used with your axle back kit to give it the finishing touch, or it can be used with your factory setup to drop some weight and help remove the restrictions. This will replace the factory x/h-pipe contraption, which will really open up the exhaust. The sound will be louder than factory, but not as much as you'd get when swapping mufflers as well.
Joe Z Exhaust
Price - $1,600
Style - Cat back with single tip
Install Type -Bolt-on
Similar to the ARK Performance kit, the Joe Z cat back will replace the majority of your exhaust system to give it the biggest performance gain and sound change. Like the ARK Performance, this kit has a very pleasing exhaust note, but it is toned down enough to avoid setting off car alarms every morning. The quality of this kit is amazing with beautiful bends and welds.
