The ULTIMATE OEM style high performance replacement muffler for your GT3 100% GUARANTEED to be the WORLDs BEST !                                                                                           

As many GT3 owners know, the OEM mufflers are prone to cracking, breaking and blowing out, particularly the titanium mufflers on GT3RS cars.  Fabspeed Motorsport Engineers design a GT3 primary muffler replacement that not only fixed that issue but also greatly improved on the OEM design in multiple measurable ways. Using our 30+ years of air and water-cooled experience, we took the valve open tubing to 2.75in / 70mm which is the optimal diameter for GT3 engines to have low restriction but maintain high velocity and high RPM GT3 pitch for the signature GT3 CUP car sound. Then, we implemented our signature investment cast 70mm 2.75" X-Pipe for optimal exhaust scavenging and maximum volumetric efficiency. The X merges the two cylinder banks without creating any restriction in exhaust flow. To maintain the factory muffler’s exhaust note and lack of drone, we mimicked Porsche’s 7 chamber design. This makes for a completely drone free muffler, even when running cat-less race headers!  Using GT3 headers with cats or Fabspeed headers with HJS German EPA approved catalytic converters along with Fabspeed GT3 Side Muffler Muffler Bypass Pipes for the ultimate emissions compliant lightweight GT3 exhaust. Fabspeed's GT3 center muffler is guaranteed to NEVER BREAK or fail- and OUTPERFORM any other aftermarket GT3 center muffler. 100% made in house at Fabspeed. 

SOUND:

This muffler will have a very similar tone to the OEM muffler, however, it will be a bit louder with PSE turned on. It will also sound a bit smoother and higher pitched thanks to our signature X-pipe.

POWER:

On our 997.1/ 997.2 GT3 and  GT3RS test car, paired with our Side Muffler Muffler Bypass Pipes, the Rennsport Muffler picked up an impressive 27 ft/lbs of TQ down low at 3,200 RPM. From 2,900 RPM all the way to 5,700 RPM it picks up =12 horsepower or more, and peak power at the wheels is up from 446 to 454! That’s a gain of over 12 HP at the crank- from simply swapping out the fragile restrictive OEM Porsche 997GT3 to the very latest GT3 RS Titanium OEM factory mufflers. BEST ADVICE- but and install a Fabspeed GT3 center muffler and SAVE you fragile OEM GT3 muffler for Concours shows and restoration. All GT3 OEM mufflers BREAK & EXPLODE when driven long and hard enough.

    Scott K was my sales person. He responded immediately on the web and continued to deal with me on the phone. I purchased a valvetronic system for my R8 and it came out beautifully. We had a hiccup during the process where the system failed their QC process. It took an additional 3 days to get the exhaust, but the expedited it and threw in some swag for the trouble. All-in-all, these guys know how to deal with supercar customers and want to make sure that the VERY small community is well cared for. I'm incredibly happy so far and would highly recommend them.

    Couldn't be happier. I wanted to add a little power to my Porsche 911 Carrera S (997.1) but didn't want check engine lights or obnoxious sound. I worked with Jason and ended up getting a GT3 throttle body and an IPD plenum with a BMC air filter and the famous Fabspeed Sport exhaust. I seriously couldn't be happier. Talk about bang for your buck! It's a whole new car. Everything works together perfectly. No torque loss at all, in fact, I found some. Mid range is more alive and she just doesn't stop pulling now. The sounds is pretty much the same at low RPMs but my God when you jump on it, it sounds fantastic. No highway drone at all. I was considering the x-pipe cat delete but Jason explained that Porsches, especially naturally aspirated (non turbo) like a little back pressure and if I was not looking for too aggressive sound I should stick with what he suggested. He knows his stuff because the car is now exactly everything I had hoped for. Best car money I have ever spent.

    I had heard great things about Fabspeed from others in the industry but my expectations were definitely exceeded with this project. The team at Fabspeed went above and beyond when developing and building the exhaust system for our NSX. With the pictures and video commentary, they made us feel like we were a part of the action and that isn’t an easy to do when you are 800kms away and in another country. I know that there were many skilled hands that were involved with making this project come to life and I would like to extend our thanks to the entire team. Moreover, I’d like to take a minute to emphasize how much I appreciated having Alec quarterback this engagement. He was a key part in making this happen and was patient, professional, and extremely responsive at all hours of the day/night. The NSX was greatly missed while it was gone but it came back with a new set of lungs and the sound is much more fitting of a car in its class. We are already considering working with them on another project and I would highly recommend them.

    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.

    Fabspeed Motorsport embodies an all-encompassing, industry-leading, meaningful experience one would ideally envision when engaging an automotive performance company for aftermarket exhaust and performance upgrades. Their passion for designing, engineering, and manufacturing the very best in exotic car performance exhaust is not only displayed in their excellent craftsmanship and elite engineering prowess, but their dedication to the customer and the customer's happiness. After purchasing the GT450 Race Performance Package for the 981 GT4, we literally felt like we were indoctrinated into the Fabspeed family. Red carpet was rolled out for us, communication was effortless and fun, and every team member we have ever had the pleasure of working with sincerely cares about our happiness and experience. Phil and Jason have gone well above and beyond expectations to ensure we are more than satisfied with our purchase and driving experience. This isn’t so much a review, but rather a wake-up call to other companies in the aftermarket automotive industry. Fabspeed Motorsport sets the bar for performance, sound, quality, and customer service in custom exotic car performance fabrication, leading by example through tireless and discerning engineering practices and fostering true connections and relationships with their customers (extended family). I recommend Fabspeed Motorsport for exotic car performance exhaust and upgrades to anyone who values objective performance, elite quality, steadfast expertise, and an honest and true sense of community in the automotive industry. Thank you Fabspeed Motorsport for a truly one-of-a-kind, elite experience. -Joshua (Tracking Ponies)
