Purchase Disclaimer: Fabspeed Motorsport does not condone the use of emission defeat devices for any vehicles used on public streets or roadways. Fabspeed Motorsport will not tamper, remove, disable, or bypass emissions equipment on a motor vehicle in accordance with 40 CFR Section 86.1854.12(a)(3), Clean Air Act 40 CFR 1068.101(b). This includes software, known as tunes, that reprogram a motor vehicles electronic control module to alter engine performance and enable the removal of filters, catalysts, and other critical emissions controls.

Fabspeed Motorsport's Maxflo Performance Package get's the most performance out of your 718 Boxster/Cayman. The Maxflo exhaust replaces the rear exhaust section with a freer flowing light weight cat-back exhaust. It's all mandrel bent for the smoothest curves, and uses .067" thick wall tubing for the perfect balance between strength and weight savings. Speaking of which, it saves 18 lbs from the car vs the factory system. We also use T304L stainless steel for all the exhaust tubing. This gives the system ultimate corrosion resistance and durability. The sport cat is built with a German made 200 cell HJS HD catalyst, which is the top of the line aftermarket solution for catalytic converters. The high flow cat further improves exhaust flow, and helps the turbo spool up faster. The BMC dry air filter increases filtration surface area over the factory unit and helps the engine breath easier and the custom ECU tune helps you get the most out of the whole system.          

SOUND: 

The Maxflo Performance Package will bring out the characteristic boxer rumble - with a much more refined Porsche tone. This system is very livable with no droning, and the activation of Sport mode greatly increases the sportiness and growl of the Turbo 4 engine. You'll also notice a slight increase in turbo spool and blow-off valve sounds.

POWER:

This complete performance package will give your 718 Boxster/Cayman 30+ peak HP and 80+ peak torque.

NOTES:

  • Simple cutting of the factory exhaust pipe is required, but is simple and reversible at any time. Please see our Installation Instructions to gauge your ability to perform the installation. If you have any doubts - please contact us for a referral to your local Fabspeed dealer / installation center.
  • This upgrade requires you to send us your ECU one time for unlocking and tuning - Shipped back with optional Handheld Tuner for future adjustments.
  • Please review our Tuning Guide below and include the ECU Tuning Information form inside the box when shipping in your ECU. We utilize this form to ensure we meet your needs and consider your modifications to deliver the best possible results.
  • While a vehicle equipped with bolt-on upgrades will experience maximum gains as a result of the increased efficiency of the engine, great power gains can be made on a completely stock vehicle!  
  • You must fill out and include a copy of the ECU Information form along with your ECU upon sending it in. Please contact us if you need to send the form in any other manner.
  • You must have access to a PC / Windows computer (Mac OS not supported) to upload new tune files or reset back to stock with your Handheld device. 
  • The Handheld device "marries" with your vehicle and can only be used on one vehicle.

No need to send your ECU in to return to stock - simply use the Handheld to flash back, then to your Fabspeed XperTune again at any point!

Why We Choose HJS Catalytic Converters: 

HJS German imported catalytic converters are made from some of the highest grade materials you can find in a catalytic converter. This yields high performance gains and longevity so it wont deteriorate over time like lower grade catalytic converters. These catalytic converters flow up to 93-95% of a straight pipe in most applications. The benefit is that you get the "straight pipe sound" while still being able to provide enough emissions scrubbing to prevent a check engine light.    If you'd like to learn more, watch our video about HJS catalytic converters.

Sport Catalytic Converter (STREET) - This product removes the OEM catalytic converters from the vehicle, and as such, is strictly intended for closed track events and off-road use only. This product contains a High-Flow Sport Catalytic Converter solely intended for track and race cars as it is NOT California Air Resources Board Certified and not EPA certified. You are hereby informed and warned to check your local, state, and federals laws before buying and installing these or any aftermarket parts to be sure whether usage is in violation. All installation-risk and use-risk is borne by the end-user and installer of these parts.

Great value for a one-time event! Perfect for graduation.
Color: Black, Size: Large, Color: Black, Size: Large
I bought this suit for my son's graduation, and it was exactly what we needed. Since he will probably only wear it once, I didn't want to spend a fortune at a high-end department store. For the price, the quality is surprisingly good; it looked sharp and he received a lot of compliments during the ceremony. We ordered a size Large (L) based on their sizing chart, and it was true to size and fit him perfectly. The fabric is lightweight but doesn't look cheap at all, making this a fantastic, excellent cost-benefit choice if you are looking for an option for a one-time event. Highly recommended!

Great for the price.
Color: Black, Size: Large, Color: Black, Size: Large
I’m 220lbs 6’1 athletic build. Arms/back couldn’t fit inside the jacket. Pants and vest fit fine though. I honestly should get stuff tailored considering my body competition. Good quality for the price worked for me.

XL sized suit review
Color: Light Blue, Size: X-Large
I ordered XL for my husband who is 6'1" and weighs 200 lbs. The pants' length was too long and we had to cut off two inches and get them hemmed. Jacket could be a little bigger in the mid section and shoulders but vest fit well. Could do without the fake handkerchief in the suit jacket pocket. Still liked the style and the color of the light blue suit.
