Hey fellas, stock 991.2t here curious to know which exhaust to get.. Id like one of the valved exhaust that goes from straight pipe no cats, to a quite or closed valve mode. Was looking at Frequency intelligence and cargraphic, any downsides to these? What do you guys think.

 

WOW sick thread dude

 

I see a lot of the valvetronic exhausts on market made in Asia, I doubt its financially beneficial for any of us to make such set up locally.... your probably looking north of $5K even for the asian ones... the trick is also how you will control the bypass. I had a shop call me from NY asking me to help them after some client bought such unit from a US vendor. All he had was some paper included with many spelling errors on generic install... you know where that came from lol so make sure you can get it to work...

good luck

Here is a dyno sheet of the stock exhaust with cats vs. the stock exhaust with cat bypass pipes. A really big bump in power for a very low cost investment. The cat bypass pipes make 20 horsepower and almost 30 ft. lbs. of torque on a 991.2 turbo.
