NAC911 Posted 7April, 2023 Report Share Posted 7April, 2023 Hi folks, looking to upgrade my exhaust for a better "Cup" style note. Already have Fabspeed Maxflow mufflers which are relatively quiet, but thinking about extractors and high flow cats. What's your thoughts and suggestions? Cheers Norm.

tomo Posted 7April, 2023 Report Share Posted 7April, 2023 200 cell cats will give it a bit more sound with the maxi flow mufflers. NAC911 1 Quote Link to comment Share on other sites More sharing options...

tomo Posted 7April, 2023 Report Share Posted 7April, 2023 Thankyou! Will extractors make much difference? Maybe to the flow as opposed to the standard headers, Which would probably be handy on a race engine, but hardly worth it on a daily, As the mufflers or lack of them is what controls the sound produced. n NAC911 1 Quote Link to comment Share on other sites More sharing options...
Carrera28 Posted 8April, 2023 Report Share Posted 8April, 2023 You might also want to look into Cold Air Induction if you want improved noise I fitted a cold air induction system to my car: Personally I think there is no performance improvement from CAI and it's snake oil when they claim it, However the induction noise sounds great. I have a full sports exhaust system on my 996 which makes a nice noise, even with that system adding the CAI added a really nice additional noise when accelerating hard with negligible increase at highway cruising speeds. If what you are after is improved noise with a louder more aggressive cadence then I would be looking at your mufflers, changing the baffles within them can increase or decrease noise and reputable shop should be able to give you options and then I would look at CAI.

911CSR Posted 11April, 2023 Report Share Posted 11April, 2023 I put a full IPE S/S system on mine including extractors, high flow cats and mufflers with switchable flaps. Made a massive difference in both power and sound... NAC911 1 Quote Link to comment Share on other sites More sharing options...
SealG996 Posted 26May, 2023 Report Share Posted 26May, 2023 I went with a Top Gear Header system, catted X pipe and mild mufflers. More alive but no drone. Quote Link to comment Share on other sites More sharing options...
