Looking for a new exhaust system on my 991 turbo! AK, Cargraphic, Carpristo, GMG, Tubi, Fabspeed, Europipe, IPE, AWE... anyone can tell me the differences? Thank you so much.

 

Topic has been beaten to death here. Did you search??

 

Kline Innovation is another great one to check! I offer a 100% guarantee you will love it.

 

Check out our full 3" X-Pipe with 3" Dual tips for maximum flow. This system can be used with OEM cats or our HJS hi-flow cats...Also available with OEM tip outlet piping.

 

Search function is your friend. Literally thousands of threads with video clips, reviews etc etc.

 

My customers have been LOVING the Fabspeed system! Makes GREAT power, sounds insane and saves a ton of weight! Check it out below!

Please contact myself directly for more information and pricing!

 

The EVOMS Clubsport system is on sale through August 14th - see here. Huge power gains while retaining the stock cats for emissions and performance, along with a more refined sound than other options out there.

 

Just installed a full Klien inconel system, headers back. System is much lighter then stock and very well made. There were no fitment issues and tech had no problems with install. At idle the car has a deeper tone, but not much loader then stock. At casual driving, sound is deeper then stock, has no drone. You are able to listen to radio and have conversation, but would rather listen to exhaust. Sport mode sounds great, burbles are accentuated, tone gets deeper. At WOT car is complete animal and head turner sound is amazing and power gain is noticeable. This is third after market exhaust I have had and by far the best. Sam at Bydesign is extremely knowledgeable and true to his word, exhaust was exactly as he described.

 

We have two flavors of Tubi in stock. The Street version with 200 cell HJS cats, or the Race version, with cat-bypass.

 

My vote goes to Europipe, by far the best quality of all of the aftermarket systems in the market today. The tone is probably the least aggressive but it also makes the most "Porsche-like" sound as well.

I heard the Tubi system in person, very aggressive but makes the car sound like another car brand. The GMG system is also way too loud, and drones at cruising speed.

 

I did Fabspeed race system with headers and I love it!

 

All the customers that we have installed Akrapovic exhausts for have come back and told us that nothing tops it.

If you need any information on details and pricing feel free to PM us.

 

What about whp between them? don't care much about the sound, just want to buy the one who make more whp

 

Catless will make the most. The point of any of these Catless or high flow catted aftermarket exhausts is to pair them with a big tune. That is where the big power gains occur. You cannot get a big power bump from a tune without a free flow exhaust.

 

That part I know... The Q is wich one with HF cats make more whp
