  • NO ECU CALIBRATION REQUIRED
  • PENDING EPA/CARB APPROVAL
  • PAIR WITH 3" FRONT PIPE UPGRADE FOR OPTIMAL PERFORMANCE
  • COMPATIBLE WITH FACTORY AND/OR MOST AFTERMARKET FRONT PIPES – NO ADAPTER NECESSARY
  • NOT COMPATIBLE WITH OUR BIG TURBO KIT, KIT COMES WITH A SPECIFIC DOWNPIPE DESIGNED TO WORK WITH THE KIT.

Technical Notes:

Research and testing has shown that a downpipe upgrade is one of the most effective modifications to perform when looking to increase efficiency out of Honda's 1.5L turbo engine. The PRL Motorsports High Volume downpipe upgrade promotes optimal airflow with virtually no turbulence throughout the body of the downpipe.

Our design utilizes 304 stainless steel investment cast ends, CNC pocketed for a smooth transition to a 4.50" OD, 400 CPSI GESi G-Sport catalytic converter for the middle body. This 4.50" OD catalytic converter was formulated for small displacement direct injection vehicles and offers optimal exhaust flow. All components are fully back-purged on site to withstand high exhaust gas temperatures. The wide shape of the cast inlet smoothly blends the turbine outlet and wastegate gases to reduce restriction, while the cast outlet allows smooth taper to aftermarket and/or factory front pipe. Pair this with our 3" Front Pipe Upgrade for maximum exhaust flow and performance! All kits will include gaskets, stainless hardware, and components needed for a seamless installation.

Exhaust components that may become damaged over time from being coated, heat wrapped or otherwise insulated in some capacity are not covered under the PRL Motorsport's Manufacturer Warranty. Insulating these components can cause heat to cause degradation of the material faster than would normally occur.

Performance Gains:

  • Increased power and exhaust flow throughout the entire powerband
  • Decreased backpressure & cooler exhaust gas temperatures
  • 400 RPM increase turbocharger spool

Kit Includes:

Good enough
Size: 15x6.8, Color: Black
As cheap as the day is long but functional. These are basically made out of highly compressed paper and finished to feel like wood. The first one I put up was good with a little tilt to the back which is fine. The second one has a more severe tilt and I had to bend the bracket down to decently level it out. They are sturdy enough to hold quite a bit of weight and look good for what they are. I'm not impressed but I'm also not disappointed, the price is a bit steep for what they are but they serve their purpose.

Great, but bring your own inserts.
Size: 24x7.9, Color: Black
These work great, easy to install. Happy with them. Only problem was the instructions say don’t use the include inserts on wallboard, which meant I had to go out and purchase my own. That’s OK, because I like to use inserts I trust.

Love the shelves, great quality and design. They are very sturdy and perfect for my need. I ordered wine glass holders from Amazon and attached them to the shelves. Impressed and amazed at the look.

Great shelves!
Color: Grey, Size: 55 Inch, Style: 2 Pack
This shelf is lovely--simple and modern. My handyman said it was easy to install AND made a note to buy it for his own rental units because he said the internal supports were very sturdy. Fast delivery and exactly as described--and the price is nice, too.
