Toyota GR Corolla Downpipe – High-Flow Catted & Catless
Unlock better turbo response and exhaust flow with the GGP Toyota GR Corolla Downpipe. Designed for the 2023+ Toyota GR Corolla equipped with the 1.6L G16E-GTS turbo engine, this downpipe is built for owners who want a more responsive, freer-flowing exhaust setup.
The factory downpipe is one of the most restrictive sections in the GR Corolla exhaust system. Upgrading to a performance downpipe helps reduce restriction after the turbo, allowing exhaust gases to leave more efficiently. The result is quicker turbo spool, improved throttle response, stronger midrange feel, and a more aggressive exhaust tone.
Available in both high-flow catted and catless options, this downpipe gives you the flexibility to choose the setup that best matches your build, goals, and intended use.
Why Upgrade?
Improves exhaust flow after the turbo
Helps reduce backpressure
Supports quicker turbo spool
Can improve throttle response and midrange power feel
Enhances exhaust sound
Great supporting upgrade for tuned GR Corolla builds
Available in high-flow catted and catless configurations
High-Flow Catted Option
The high-flow catted version is the better choice for customers who want improved exhaust flow while keeping a catalytic converter in the system. This is the more balanced option for street-driven builds, customers who want a cleaner setup, and owners who want a performance upgrade without going fully catless.
Catless Option
The catless version is designed for customers who want maximum exhaust flow and the least restriction possible. This option is best suited for off-road, race, and track-use builds where emissions compliance is not required.
Construction
Built from stainless steel for strength, heat resistance, and long-term durability, this downpipe is designed to handle the heat and abuse of a turbocharged performance setup.

Stainless steel construction
TIG-welded design
CNC-machined flanges for proper fitment
Flex section to help reduce stress and vibration

Important Notes
Tuning is highly recommended to get the best performance from this downpipe.
A check engine light may occur depending on your setup, tune, and downpipe option.
The catless option is intended for off-road and competition use only.
The high-flow catted option may still affect emissions compliance depending on your local laws and vehicle setup.
Professional installation is recommended.

Everything was perfect. I purchased this from Japan, and the service was prompt and courteous. I'm really grateful for your help!
A must have upgrade for your GR Corolla. This unit eliminates the side to side play that the factory shift linkage has. Nice, tight shifting post install. Awesome upgrade 👌🏼
Great Part!

Deatschwerks Set of 3 1100cc Injectors Toyota GR Yaris | GR Corolla 2021+
Awesome shirt, love to rep my car even when I’m not in it! I wear this everywhere! Very comfortable materials, the print on the shirt feels quality, I absolutely love how the colors pop.
The background print is too dark. The outline of the trees cannot be seen. The tombstones are very dark and the names on them cannot be seen. Cannot see the wheels or grill.
Nice quality and fits good. Love the logo!
Fast shipping. Great quality and much lighter than OEM. Grat carbon fiber finish!
Love being able to pick my car color. Might go for the long sleeve in a few months.
High quality, great fit and looks great next to my GRC!
Ordered an ice cap tee. No idea how a chose a small for my dad bod but my mistake was my daughter's gain. She immediately stole the shirt because we work on the car together. The Grey color is perfect for the colors in the design and makes the red pop. The design is sick and the quality shirt is really really nice. So much so I ordered the right size immediately! Buy one!
This hat…what can I say? Do you want to be the talk of the GR community? Do you want to have people look at you and know you mean business? Do you want keep the sun out of your eyes (wearing it forward of course)? Do you want to be successful? If you answered yes to any of these, then this is the hat for you! The fit and feel of this hat is perfect, much like the Brin Naub® and synthetic leather-trimmed sport seats in the GR. The embroidery seems as though it was done by the hands of angels, every stitch to perfection. When I first put this hat on, I lost 15lbs and gained another 15lbs in muscle (can’t confirm it scientifically, but the scale stayed the same and I felt stronger). My senses while having this hat on were also heightened. The 6 speed manual transmission in my GR Corolla didn’t stand a chance as I flew through the gears masterfully while passing the Ferrari SF90 stradale awd that couldn’t keep up with me (it may have been slowing down to turn, but pretty positive they saw me and knew they couldn’t keep up). Bottom line is, you want this hat, you NEED this hat. I’d recommend buying atleast two of them for when people notice you’ve become too powerful and try to steal your hat. Always have a backup! And remember, with a great hat comes great responsibility, or something like that. Buy this hat now!
Love the design of the shirt!! I ordered two of them and they were delivered quickly after. My family loves this shirt as I have a HM GRC. Next time, when I order again, I’d consider getting one size larger.
Graphics are sick, they’re printed well (screenprinting feels thick, like it won’t crack, fade or peel so that’s good) printing seems accurate (back is perfectly centered), blank material is always s tier w comfort colors so that’s good. 10/10 will buy again
Everything was good 💯😊

Going to make this short and sweet, was going to order my MBRP exhaust through a different company but before that I had onesix In the back of my head. The experience I had was top tier. They answered every single question and kept me in the loop with shipping. I would definitely recommend buying from these guys! They're in it to make sure the customers that buy from them are more then satisfied...but well taken care of.

Easy to mount, works without flaws and the biggest thing is that it minimized the brake dust from the original pads. Recommended
