the bloke who posted the video is determined its not a Turbo, he says its a GT3 with RB TECH exhaust. So I don't really know if that exhaust is credible for this thread....

 

Did the Europipe owners noticed and power loss at any rpm???

 

None that I noticed.

 

wow... what a work of art. Looks very similiar to my ep2 for 996tt

 

looks incredible

 

I love Europipe exhaust system an i think i have found my way, just wandering if i should change the headers too

 

yes....best possible choice.

you can see how nice box you will have too

 

too bad you cannot just replace 200 cells on the stock exhaust, to gain power and lower back pressure, instead of spending 4k plus plus resonance

 

I believe Ruf does just that with the stock system, of course it ain't cheap.

 

Actually Ruf uses a 100 cell cat.

 

Hey thats actually quite a good idea, somebody should try this, cut out the cats. I believe someone is giving the 997TT exhaust away for free... worth a try!

 

It was supposed to do that to my exhaust, but then i decided to go first with 100cpsi cats (130mm diameter) and mufflers bypass. If it sounds too loud then the cats will be welded to the stock muffler with some minor adjustments.

But for a cleaner job, cut the OE cats by the welds and replace it with sport cats with the same size. The OE cats has 118mm diameter and there are a bunch of 120mm sport cats (100 and 200 cpsi) in ebay for about $300 (yes, two cats for ~$300), that can be direct welded to the stock flange and muffler (no need to make O2 sensor bungs).

and why U.S tuners use kats from europe ?

and why ruf does that? because they earn on this a lot, they charge for that probably same like for sport exhaust.

 

How about our new 997TT 2nd generation sport muffler´s with 200 cell HJS cats for best 997TT muffler??

Here is a video on a customers car...

Finally i have installed my new Europipe stage 1 exhaust, to be honest i had a fear that it would be too loud for my convertible but it is not.

It sounds just right, is difficult to notice the difference from the stock exhaust when the car is stoped, but when you step on it is screams like hell.
It does not do any anoying sound at any rpm.

My car is a tip and i think i have lost a bit of torque at low rpm, noticed on 3rd a bit but the ECU will fix that

I think what makes this exhaust unique are the XXL 100cel cats, where at low rpm and crucing the car sound close to stock but when you push it is a different story
