4.5L pistons and rods are finally inbound. We tested the GT3 intake manifold and not so good on the stock engine, took all the torque away. We're working on something bolt on that will be better!

Thanks for the discount! Have you guys tested the quiet GT3 exhaust on the GT4 yet? I want to pass sound next year with my DMS headers

Interesting, thanks for doing that testing and excited to hear that you're working on something better! I was pretty excited to hear about the GT3 intake development but after overlaying a GT3rs dyno over my GT4 dyno I was concerned about just that, the GT3 really seemed to give up low end torque in favor of keeping a decent top end. Fine I suppose if you can spin 9k rpm with gearing to match but maybe suboptimal for a bolt on GT4 build. I bet the increased mid range new 991.2 GT3 owners are raving about is as much to do with the intake revisions as the displacement bump.

The quiet GT3 muffler on a GT4 we expect to do the same as it does on the 991 GT3, take away 10-12dB. Now the GT4 is mighty with race headers on it, so it depends on the club and the limits. May need to do Cats and Quiet muffler to reel her in...
