Toyota GR Corolla Downpipe – High-Flow Catted & Catless
Improve exhaust flow and sharpen turbo response with the GGP Toyota GR Corolla Downpipe for the 2023+ GR Corolla equipped with the 1.6L G16E-GTS turbo engine.
The downpipe sits directly after the turbocharger, making it an important part of the exhaust path on a turbocharged setup. Replacing the factory unit with a freer-flowing design can reduce exhaust restriction, improve response, strengthen the midrange feel, and give the car a more aggressive exhaust note.
This GGP downpipe is available in both high-flow catted and catless configurations so you can choose the setup that best matches how the car is used.

Tuning, CEL & Installation
Tuning is highly recommended to get the most from a downpipe upgrade. A check-engine light may occur depending on the vehicle, calibration and downpipe configuration, so a CEL-free result is not guaranteed.
Professional installation is recommended. The high-flow catted option can still affect emissions compliance depending on local law and vehicle configuration. The catless option is intended for off-road and competition use only.
Why Choose the GGP Downpipe?
This is a Grocery Getter Performance product for GR Corolla owners who want a straightforward choice between catted and catless configurations, solid construction, proper fitment and strong value. GGP supports the GR Corolla platform directly and can help customers choose the configuration that makes sense for their build.
Installation was straightforward and the build quality is excellent. It looks great on the car and has noticeably reduced intake air temps. Highly recommend it for any GR Corolla owner.
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 👌🏼
I could not be happier with my purchase. The customer service throughout the purchase and the shipping of the exhaust was next to none! An overall amazing experience, and a pleasure to order though. Highly recommend.
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.
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
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.
So excited to get this exhaust. I had it installed the weekend after I received it. I have gotten sooooo many comments on the sound as well as the looks. I really love it.
