Amazing service, very welcoming and professional staff. Great facility they have, you can do almost anything you want to your car in their facility. Scott helped me out and got me everything I needed. Only bad thing I would say is their hourly rates are pricey, but honestly amazing job they do. 100% recommend this place to anyone with a modern European sports car. Thanks Scott and Joe
I have no words to express how wonderful the entire Fabspeed Team - especially Vince Dean and his tremendous advice and guidance - have been as they have helped me achieve the maximum power, sound, and performance from my 2019 Cayman S. Vince's advice in regards to the MaxFlo Exhaust system was spot on, and the results have been amazing - an exhaust note completely unleashed (especially when in Sport Mode). Great communication. Prompt and most helpful responses and advice. Fabspeed has been a true gem in all respects. Highly recommend this team.
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!
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!
Total satisfaction! The crew at Fabspeed is top notch and makes a incredible product. My Porsche has come alive with their new sport cats. Look forward to adding more products from Fabspeed.
