Overview

Important Notes:

  • 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

Great for keeping bank statements clean but random security delays are frustrating
Reload type: One Time Reload
I use the balance reload tool to manage my monthly budget and easily hit credit card sign-up bonuses. It keeps my bank statements totally clean by grouping dozens of tiny e-book and movie rental charges into one single transaction. Most of the time the whole process works flawlessly and the money shows up in my account within five minutes. It is honestly the easiest way to put a hard limit on my family's everyday online shopping. You just need to watch out for a few annoying system quirks when you load larger amounts of money. Even though it usually works instantly the automated security filter sometimes flags big reloads and freezes the transaction for hours. This random delay is incredibly frustrating if you are trying to add cash fast to catch a lightning deal before it expires. You also have to remember that this balance is strictly non-refundable and cannot be used to buy other gift cards. Overall this is still a great method for organizing online spending and maximizing your cash-back credit card rewards. It totally fixed how I track household purchases but you definitely have to tolerate the occasional processing delays. My best advice is to load your account a day or two before you actually need to buy a big-ticket item. It works perfectly as a budgeting tool as long as you know the rules and plan for the random security hold.

Just What I Needed for My Home Office

I’ve been very happy with this office chair. It was straightforward to assemble, feels sturdy, and offers excellent support for long hours at my desk. The adjustable lumbar support, armrests, and headrest make it easy to customize for a comfortable fit, and the mesh design helps keep the chair breathable throughout the day. Overall, this chair is comfortable, ergonomic, and a great value for a home office setup.
