The ULTIMATE OEM style high performance replacement muffler for your GT3!                                                                                           

As many GT3 owners know, the OEM mufflers are prone to cracking, breaking and blowing out, particularly the titanium mufflers on GT3RS cars. We wanted to design a muffler replacement that not only fixed that issue but also improved on the OEM design. Using our 25+ 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 GT3 pitch for the signature GT3 CUP car sound. Then, we implemented our signature investment cast X-Pipe for optimal exhaust scavenging. 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 catless race headers! Pair this with our Side Muffler Muffler Bypass Pipes for the ultimate emissions compliant GT3 exhaust. This muffler is guaranteed to NEVER BREAK or fail.

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 991.1 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 10 WHP or more, and peak WHP is up from 446 to 454! That’s a gain of 8 WHP or 9 HP at the crank.

FEATURES:

  • Fits all Porsche 997.2 GT3 / GT3 RS vehicles 2010-2011 worldwide
  • Constructed from CNC cut T304L stainless steel
  • Designed from 3D scans of the OEM muffler so we can achieve perfect bolt-on fitment
  • Will not break or crack like OEM GT3 mufflers do
  • Incorporates our signature cast X-pipe for superior flow and exhaust scavenging
  • Paired with our Side Muffler Bypass Pipes this muffler adds +27 ft/lbs of TQ and +16 WHP or +18 HP at the crank!
  • 3 different tip options available
  • Completely retains PSE valved exhaust functionality
  • No Check Engine Light guaranteed
  • This cat-back system is emissions legal in all 50 states and the rest of the world
  • Built in house at Fabspeed Motorsport USA in Fort Washington, PA
  • Simple bolt-on installation, no cutting or welding required
  • All Fabspeed performance products are backed by the Fabspeed Lifetime Warranty

A Perfect Gift For Someone Who is Tough To Buy For
Size: 5.3 Inches - 2 Packs with Holder
Very attractive looks and quality build. Most importantly the salt grinder will take sea salt down to powder for popcorn (a make-or-break feature in my house). It doesn't take up much room in the cabinet when stored and very easy to fill. We're just delighted with the value for the money. Any time you are stuck with what to get someone for a birthday, xmas, what ever; you can't go wrong with this Salt & Pepper Grinder Set.

It works but it's not high quality
Size: 5.3 Inches - 1 Pack
Grinder works well except the silver part came loose after using it a couple of times now we have to hold the top part really tight to use it probably should have returned it but it still works

Good Salt Grinder
Size: 5.3 Inches - 1 Pack
Bought this for the pink salt. It crushes it nicely and is easy to fill. The crushing didn't change the taste and this holds a considerable amount of sale. It's a great value for the money and would make a terrific gift.

Works great!
Color: 1 pk
I almost returned this item because, as some others also mentioned, the top is very hard to remove. It needs a little indentation for your finger! But I liked the size and style so I persevered and once you remove it a few times, it eventually comes off easier. This grinder works beautifully. It’s lovely on your table as well as your spice rack. The adjustable grind levels makes it easy to use and I highly recommend this item.

Exactly as I it hoped it to be!

Such a great, little pepper grinder! Works very well and the adjustable grind size is a nice feature. Highly recommend if you need one that doesn't take up too much space.
