The Maxflo + Sport Cat Package gives you all the performance of the Supersport Turboback Exhaust system but with a much more civilized tone and volume level. 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.
SOUND:
The Maxflo Catback combined with the Sport Cat gives you a bit more volume than just the Maxflo Catback by itself, but it will still retain the refined Porsche tone.
POWER:
Expect peak gains of 5+ peak HP and 15+ peak torque in your 718 Boxster/Cayman
FEATURES:
NOTE: 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.

i have their secondary cat by pass pipes and maxflow mufflers on my 958s. i also have their supersport exhaust on my 991. both sound amazing. i recently had a minor concern/problem and contacted them. john palo reached out to me the next day and sorted everything out. its been well over a year since i purchased and he took care of me no questions asked. johns customer service is top notch and i just wanted to write this review to thank him. great products and even better customer service, thanks fabspeed and john!
Great support from Alec. Extremely knowledgeable, I asked a ton of questions and answered everyone patiently. Look forward to my new Porsche upgrade.
Firstly, I want to start off by complimenting the customer service I received from Fabspeed. I worked with Gary from the beginning and he was nothing but helpful, answering all of my questions and helping me understand exactly what I wanted for my car. Once I picked out what I wanted, the ordering process was easy and the package came FAST! Install was easy and the end results were AMAZING. Simply installing their headers took my car from sounding cool to COOL!! I get so many compliments on how the car sounds and everyone is blown away to learn that I only installed headers with no tune. I could not be happier with the result, especially at a relatively low cost. THANK YOU FABSPEED!! Can't wait to work with this company again in the future.
Great team and outstanding products. Thank you DJ for all your help getting my Porsche 991.1 all setup and sounding amazing.
Just got my Fabspeed Maxflo Mufflers installed on my BMW E90 M3! Could not be happier. I have a fully catless setup, and had trouble finding a suitable rear section that would bring the car to reasonable volume levels, reduce drone, and cut down on the inherent "raspiness" of the S65. This exhaust ticks all the boxes! The volume level is surprisingly tame for the car being fully catless, but certainly louder than the stock rear section. In-cabin noise or "drone" while cruising is greatly reduced compared to the muffler delete I was running previously. Exhaust is absolutely perfect for a daily driver. The "rasp" is just right as well. Sounds incredible on the downshifts. Power and low end torque, surprisingly enough, increased greatly. I keep getting compliments from people at car shows, gas stations, and even at stoplights. Fabspeed was an excellent company to deal with as well. The owner Joe Fabiani is a stand up guy, and scheduled me in super early on a Wednesday morning so I could make a business meeting later in the day. The service was fast and professional, and their tech Dustin walked me through the exhaust setup on my car, and allowed me to customize my choice of tips, and assure their placement is perfectly to my liking. I've read some distasteful reviews of Fabspeed as of late, but the majority of them are frankly not true. I am a former employee of the company, and have seen all the ins and outs of the sales team and fabrication facility. There is nothing out of the ordinary to see, and they will give any walk in customer a full tour of the facility showing off the cool equipment that they have to produce their systems. The recent slew of slander and distasteful reviews stem from one customer who tracked his car with a Fabspeed product not designed for the track, voided his warranty, and was stuck with the product. Fabspeed eventually made the situation right, but this customer has a reputation for slandering other businesses and throwing them under the bus for his own personal gain. It is painful to watch a company such as Fabspeed have to endure something like this, hence why I feel the need to address it in this review. Overall, great friendly service, awesome product, cool facility, and one AMAZING sound!
