I was only able to mostly putter back home during rush hour traffic, but yes, it's not for the faint of heart.

Will do.

I think it will always seem loud . But that's ok. I love loud cars. What setup are you running?

JB911

One thing to consider is the center bypass dimensions-I have the FVD(M&M) center bypass which is similar in design to the Sharkwers. The lower section of the pipe is in a straight line. Others like GMG, Soul and a few more have a progressively fatter lower pipe just before they turn towards the tips and I'd imagine it's a deeper sound. When I get around to installing valved sides with my M&M I'll end up with that kind of setup. I have the Carnewal remote for the valves, so on cold starts and until Im out of the neighborhood I'd leave the valves closed, it makes somewhat of a difference from the videos I've watched-

But in your configuration, you still have your OEM side mufflers correct JB911 ??
.... btw, thanks again for convincing me to go with the Carnewal. I still love it, and swear by it. SO much better to creep out of my garage & off my street before I open the valves.

Ed, Thanks for posting the pics. Looks sick,... and probably sounds even better. I like loud cars too.

Hi Steve,
I currently still have the stock sides but will be installing valved side deletes, hopefully soon. I'm selling my OEM center in case someone needs an extra one-
As for the difference in sound between center deletes, the straight type like Sharkerks, M&M etc vs GMG, Soul, BBI which is progressively fatter before exit might be the timber difference between a trumpet and flugelhorn(?)

I believe the progressive design of my Soul (similar to BBi and GMG) creates the deeper aggressive tone in the low to mid RPMs as compared to Sharkwerks. But in the upper rev range, it certainly changes from deep to higher pitch rasp (the good kind of rasp!). I believe most set ups will sound similar in the upper rev range with respect to the 'tone' and only the volume of that tone will differ based on set up. I went with Soul because its a mix of BBi and SW (BBi progressive pipe design, SW rear cross pipe design). And also John Gaydos is awesome!

BTW, the new RSR with exhaust ahead of the rear wheels sounds horrible, like a vuvuzela 😂
I’ve been watching and listening on YouTube since the new car was unveiled. From what I’ve read, the side exhausts frees up the diffuser area etc. But the great sound is gone. Hopefully they’ll re engineer things and it will sound great again, like this😀:

Mr. Adair

Sounds more like a 996 RSR now. The change really improved the packaging. No longer have to run that long exhaust pipe all the way to the back of the car. But yes, that was the best ever sounding GT car IMO.

Mr. Adair

Same car at the corkscrew at Rennsport. So nasty! Sorry, there was supposed to be a video attached to this comment. Oops..

^ Sounds just like my car - except I shift faster

lol

awesome

Need to get some flyby footage, but here are before and after cold start vids. Revs to 3-4K at the end. Let the idle drop before I goosed it. Took a spirited 100 mile drive today. And as previously suspected, it's crazy loud. My ears were ringing when I got home. It sounds great, so no plans to change back. But I'll probably have to start wearing earplugs for extended drives.

Sharkwerks center bypass only

Ok that does sound bad *** but I bet it is loud.

You are killing me having the Ford sit there and not giving us a clip of starting it and doing the same thing!

Haha. I've got plenty of vids of my FGT on YT. This being a Porsche forum, not everyone shares my enthusiasm.

------------------------
Jamie gives some great advice and makes some great Porsche 3D printed intakes. These GT3 cars are not complicated BUT there are so many choices for determining sound levels and power levels with resultant sports car sound. GT3 side muffler bypass pipes with Helical Aerospace United Kingdom Ltd. exhaust valves are a super upgrade for all these cars. Obviously as shown above in a photo Fabspeed has been making these GT3 smb pipes with/out valves but that loses PSE.

STREET RACE GT3 Lemans sports car sound track: If I had a GT3 and it was my street & mostly track car, that did not have to be emissions compliant, I would likely run GT3 long tube headers with GT3 side muffler bypass pipes with Helical exhaust valves. Fabspeed Motorsport USA is the exclusive USA imported of Helical UK Porsche OEM Tier 1 quality exhaust valves. (Fabspeed Motorsport stopped using Chinese exhaust valves over 7 years ago as they 100% break, rattle and explode- its public domain and we are still fixing replacing Chinese sandblasted exhaust valves. Caveat Emptor) . I would run the stock OEM GT3 center muffler with a muffler save stiffener or buy Jamies strong replacement. If you want even louder we make rear muffler bypass pipes and center muffler bypass pipes with Porsche AG top balance tubes.

2nd if you want emissions complaint then RUN the stock OEM catted GT3 headers. That greatly reduces attentuates sound levels and then do side muffler bypass pipes with Helical Exhaust valves and the stock OEM rear muffler. Another option is our Fabspeed center muffler bypass pipe with cross over pipe Porsche original style. If you want more throaty sports car sound another option are quality GT3 rear headers with HJS Emissions technology German 200 CPSI HD extra large catalytic converters. FYI- Fabspeed Motorsport USA is the exclusive importer of HJS systems and we buy direct from HJS and obtain genuine certified warrantied product.

For guys that want to save maximum weight and not have their OEM Porsche GT3 center mufflers explode at Track events other options for being street legal are a complete rear X pipe that replaces both side mufflers and the rear center muffler. It works great and sounds loud and proud but really good beacause of our Fabspeed rear X pipe that blends both sides of the GT3 exhaust banks and gives a high pitches sports car sound.
Ill tell you what if any of you want to try a quality made system let me know and email me I can get out samples to the GT3 Faithful. See some of you at Daytona. Pulling for #912 and #911.

For me the solution for side muffler delete is a simple and cost effective one, if one does not care about a valved set up.
First save your OEM parts.
Then purchase and install a Supersprint side pipe and center muffler combo. This system has integrated tips, has a 3 year warranty, and passes TUV sounds testing. Supersprint quality and engineering is very good.
It is hard not to pass up such a great deal (also, these were on sale for 20% off at ECS Tuning....so keep an eye open for another sale).

i was planning to purchase this system for my GT3, but my budget for that car has been chopped this year......(due to the acquisition of a 1998 RUF Turbo R project....with W09 VIN, )

^^^ wow that sounds loud though,... and Mr Adair's goal is to actually reduce the decibels from the system he has now.
