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

  • Paired with our Side Muffler Bypass Pipes this muffler adds +27 ft/lbs of TQ and +16 WHP or +18 HP at the crank!

Quirky, small, and not for everybody
Color: Black/White/Black, Color: Black/White/Black
This is an attractive little watch, similar to the older Timex Expedition, but changes have been made. Like its earlier version, this is a small, light timepiece. The band is something different, with the case being held in place by an elastic insert sewn in. Pro - This watch stays put on the wrist, making it a good work watch. Con - pins will have to come out to remove band or change the battery. Another unique feature is the use of triangle slot retention screws on the back of the case, no doubt requiring a special screwdriver most folks probably don't have on hand. The band Velcro's into place, appears best for small or medium wrists, and stays where one puts it. In sum, this is a handy and attractive watch that is quite informal in appearance and will require some patience to perform battery changes.

Simple, easy to read, dependable, and affordable: all the important stuff!
Color: Black/White/Black
Its just a fine time piece for daily wear. Its light, its super easy to read both day and night. Its comfortable and it looks good on your arm. What more can you ask of a watch? If you want "fancy" go buy some high dollar metal case thing and pay three or four (or more) times what this watch cost. If you want to know what time it is and not spend a bunch of money, this is your baby. You can find cheaper watches, but you will not find a better watch at this price. I know, I have been wearing out watches for decades! My work is hard on watches. Things like using power tools, impact tools, hammers, welders, etc. These watches have never failed me and have lasted longer than watches costing far more. I got my first Timex watch nearly sixty years ago. I am still buying them as I have found nothing else that is more accurate or holds up under harsh conditions any better. You get what you pay for except with Timex. They give you MORE than you paid for.

I like the nylon strap.
Color: Black/White/Black
Watch itself is fine - doesn't stand out as something spectacular but is great for what it is. Definitely waterproof to about 30 feet deep - I've tested it snorkeling. The best thing is the strap - this nylon strap is much more comfortable than usual watch straps. There are a lot of nylon straps out there -- I think I prefer this one more than most of the others. the Velcro allows infinite adjustment, unlike straps with holes like a belt. And the way they did the looping of the band around itself seems to work really well. Better than another velcro strap I had many years ago ("the band") which was similar but didn't loop around itself the same way. This one is better - quicker and easier to put on and more easily adjustable.
