Any advice on a exhaust system for 991 GT3 ?? something with more "pops" & "crackles" during the downshift !!!

Thanks

 

Cargraphic!!! Shoot me a pm if you are interested and i'll get you a price.

 

IPE nothing sounds more radical for GT3 honestly. http://www.ipe-f1.com/products.php?b...86552864342025

 

PTI but is this just their center section exhaust or the full monty?

PM for pricing please of each section, thanks.

 

Their website claims their exhaust puts 12 additional ponies at the wheels. Seems like a stout claim?

 

I decided against iPE due to that really weird dip in the dyno plot. I'm not sure why they would put that on their website unless they kept getting the dip after doing multiple runs.

The other problem with the iPE is that you still need to force the valves open. If you want to retain the PSE button, you will still have the same operation as OEM with the valves opening around 4,000 RPMs.

You can use their remote and program a mode with the valves open all of the time, but you can't use the PSE button then. I think it's clunky to have to carry around another remote.

I'm still holding onto hope that someone will come out with something that fixes the valves. AWE, Fabspeed, Tubi, Super Sprint. I wonder what Akra's new full exhaust does.

 

My ears were burning

Stay tuned, we have some things in the works for the 991 GT3

 

The problem, as with all after market exhaust systems, is drone. I have tried a lot of
different systems, not on GT3s, and they pretty much all have some drone. I have
heard good things about GMG, at least their Turbo systems. My local dealer bud now
uses their systems over another he used to do business with.

 

I installed the bypass last week. Very minimal drone with the values closed at HWY speeds. Other than is has a great sound, reasonably priced comparatively speaking, and it has felt a little quicker. Judging solely off the seat of my pants. Install took me about an hour, maybe a little more.

 

Joe,

We need a rear section that doesn't destroy low-end torque that is operated by the PSE button. When you press the PSE button, the valves should be open at all RPMs like on a C2S. It would be nice if we didn't get a massive amount of drone as well. Basically, I want my 991 to sound like a 997. At least that's what I'm hoping to see.

 

I agree... Cargraphics. Another solution is Sharkwerks. We just had an order for Cargraphics. Install coming up next week. Cargraphics has some of the fastest shipping, if wait time is an issue.

PM for excellent pricing.

 

What about WHP for those systems?

Did anyone try the CUP Exhaust?

 

Just wanted to wish you all Happy Holidays and thank you for all the support in 2015.!!
