Constructed from T304L high-quality stainless steel, Fabspeed Motorsport AMG GT/GTR/GTS Sport Catalytic Converters offer premier quality catalysts by utilizing HJS Germany Tri-Metallic 200 cell catalysts. We perfectly match the sound expected of the AMG GT cars by dramatically improving sound and power throughout the RPM range offering a much-needed solution to the boring factory exhaust. Using only certified high-performance HJS components imported directly from Germany, our system eliminates all risk for black market, grey market, or counterfeit HJS catalytic converters from other companies. Increase the muscular twin-turbocharged Mercedes Bi-Turbo sound and reduce backpressure allowing for much quicker turbocharger spooling and transient turbo response. Fabspeed sport cats replace the restrictive OEM 800 cell catalytic converters with HJS Emissions Technology catalysts guaranteeing NO CEL (Check Engine Light) (on US cars only).
SOUND:
Optimized for maximum performance and sound, the rumble at idle is significantly improved and adds a much-needed pop and burble on the downshifts. Now, for the good part. On throttle, your AMG GT car is noticeably more throaty and alive with completely free-flowing sports car sound exhaust notes and completely drone-free.
POWER:
We dyno tested these Sport Cats on our in-house Dynojet. At the wheels, we saw max gains of +10 who and +10 ft/lbs TQ.
Provided is our easy to use INSTALL GUIDE.

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!
I absolutely love my new X Pipe exhaust for my Porsche Cayman. There was an issue with the new exhaust tips fitting correctly. I contacted Fabspeed and spoke with Ted. Their customer service is beyond anything I have ever experienced before. Ted shipped me a set of new exhaust tips and they fit perfectly. I've gotten many compliments on how they transform the look of the car. I will be ordering a full exhaust sometime next year and am excited it will be from Fabspeed. I recommend this company 12/10.
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!
Purchased an exhaust for our 2000 Porsche Boxter S. What a fantastic product. Sound is amazing, and the car does indeed feel a step faster. Customer service follow up was amazing and am already shopping for the next performance upgrade for our 986 Fabspeed manufacturers. Highly recommended.
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.
