When they will release for new GT3RS?
Also what you think i need to install to have as loud as possible exhaust (991 GT3RS) ))? But to keep the exhaust button working (silent/loud)

Thanks

Tryptomine,

Our current exhaust for the 991 GT3 should fit the new 991 RS and we will be confirming this week as we have installs scheduled. As soon as it's confirmed, we will be taking orders.

Regarding your second question, you would want to replace the headers and the center section to make it as loud as possible, while retaining the sport button. Most of our clients that want that option run our GMG Header and Center Section combo.

Love all your write ups / videos Matt!

Get the GMG header with 200cel cat and GMG rear muffler bypass, retain the factory mid muffler, Done. The exhaust button will be functioning while you have loud exhaust. lol

I purchased a Sharkwerks from another forum member, it arrived and I let the package sit in the foyer for a week while I remembered Sean's GMG at the Spring Smokies event and then Matt bought a GMG and those videos won me over. Sold the Sharky without even unpacking.

I want to thank James and all the guys at GMG. I ordered a black ceramic coated GMG bypass and they got me one out right away.

A pesky race car was stranded on my lift for front suspension work so I didn't get to the GMG install until today. Kudos to anyone who removes the stock center muffler on ramps or jack stands - lift made it not too bad. I left the valves connected.

I had time for a quick drive before a major rainstorm moved into the area - the sound is perfect, agressive startup and really good tone above 4k. Love it.

Matt and Sean both say very little drone at highway cruising speeds, I'll report back after a couple more drives.

Awesome Ryan! I need a lift in my life!

Oh yes, yes you do.

I installed mine myself. If you buy one and need a hand with setup give me a shout.

Congrats Ryan!

If it weren't for the sound regulations at AMP I'd already have one on my new GT3. I am still trying to figure out what to do. I miss the RRRRRIP of that GMG.

I have not experienced a GMG, but my Sharky at 9K is flipping nuts.

I bought my GMG from Sean. I heard it on his old GT3 and liked it more than the SW on my old 997 GT3.

Yesterday I put catless headers on my car. The sound now goes to 11 at the top of the rev range. Someone encourage Matt to buy some and make a video.

I'm running a shark but should have a gmg by next week. Can't wait!

MM,

I hate to cost you more time and money, but you really have to try the RSS X-Pipe before giving up.

No affiliation, just felt it was the most perfect exhaust note of any sports car I have ever heard when I had it on my 7.2GT3.

Curious why it was not on top of your list of bypasses to try?

Any idea how loud The RSS is? I am debating it but only if it will pass 101db restriction at my local track

allans

98 db, no?

sgroer

Yes. 98. I wasn't thinking straight. I wish it were 101!


I'll be there tomorrow at 9 exercising my gt3.
