Exhaust sound, performance /catless options
#16
Al, we do a lot of sound testing/R&D during our design phase and we spend the time to get it right. Not many aftermarket exhaust manufacturers spend the time or put in the effort that we do to insure quality of sound from our 2.5 quiet to our 3" competition loud systems and when you don't, you can easily end up with inferior or just plain bad sound characteristics. That GT3 type sound is our goal and over the years we have learned ways to bring it out. I'm glad to hear you are enjoying your exhaust!

Yes, the lighter, slip on design requires removal of the rear mufflers. But I think pretty much any exhaust will, as you have to slide off the studs on the turbo hot side.
#18
Yep that's it. The dual tips are next. It will be a little louder John tells me.

I have a Kline 3" GT2 exhaust with the X and small titanium mufflers. When run with the 100cel cats, it is very mild and quiet. I have switched now to the decat pipes, and it is still nicely muffled, with just the good growls, burbles, and pops coming through. There is some volume at full load, but it is a deep roar, very pleasant. I am very surprised at the moderate sound level. Coming from a Cayman S with longtube headers and race mufflers, this is tame in comparison.

Morning guys,
Current exahsut set-up;
Evoms Race headers
Fabspeed Cat deletes
Sharkwerks 2.5" X
Speedtech Ceramic Coated dual tips
I purchased from John at Speedtech a true full 3" catless exhaust with 3.5" dual tips which will be installed next week, which means that my current exhaust with the exception of the headers will be up for sale if anyone is interested. Can't wait to get this new exhaust installed, John has great customer service and is Porsche enthusiast like the rest of us.
Regards,
Manuel

Here is what it sounds like at full beans during the beginning of the run. Nice burble and pop.

First and foremost, Nice driving dude!
Car sounds good. I know its a video which means it may be slightly quieter but, it sounds good. Your video started to sound like a V8 half way though? Once I saw the vet, I understood the sound change.

My speedtech exhaust was incredible!

It does indeed. I get nothing but complements. I'm considering 200-cell cats, but not catless. I'm too old for that nonsense

Promise it's nowhere near too loud. The DFI TT motor is insanely quiet. The turbos act as mufflers. It was quiet still without cats. And no drone. It is even quieter if you leave it in regular instead of sport+. Only gets loud if you got WOT above 4500. My M4 with stock exhaust and just down pipes is way louder.

Here is a 997.2TT 3.0 catless we just completed for a customer. Only 16.5 lbs. as pictured.
