OMG Cargraphic sounds so good! So does the EP. Does the Cargraphic kit 3 include headers? what is the powergain with cargraphic kit 3? 40hp power gain on EP sounds almost to good to be true?

Sorry confused? Where did you see 40 hp gain? Not sure anyone has achieved such numbers.
Just as an aside, would like to see dynos done with the decklid closed. Just currious

Although the car in the clip is a Mk2 its sounds a bit much with a 40hp powergain.

"A friend of the staff at Hyevon brought in his new GT3 for a little exhaust swap. We removed 2 muffler, 2 valves, and about 65 lbs worth of extra weight. The new exhaust weighed in at around 9 lbs and increased HP by about 40."

Sorry but I say again. Other than they claiming it, where do you see the 40 hp gain?
Nobody's hardware has achieved such gains.
On the video that's Sammy's GT3 which sounds great and as I said above. His gains for the money spent is the best bang for the buck.

I dont see it anywhere else, i asked a question, hence the questionmark. I thought a 40hp gain sounded too much.

I had the Akrapovic race system, and it sounded amazing and provided solid gains(Stock/Akrapovic race exhaust/ Tune+gas+akrapovic race exhaust dyno):



Since Im in the process of switching cars, I sold the Akrapovic and put an Europipe for now. The Europipe is much louder, too loud for the street (for me) but does sound great. I cant really creep around at high speeds anymore
I'll be dynoing the Europipe, probably this week in the same dyno, just to see how it compares with my previous set up. If I decide to keep the GT3, I'll most likely be putting back on the Akrapovic race system...

Here is a vid of the Akrapovic race titanium exhaust:

any reason why you moved over to a SW?
Europipe markets that exhaust as a track exhaust, it was extemely loud. I loved the sound and its not that it was too loud for me, but felt a little ridiculous, almost rude.

I had the sw bypass first, so went back to that for now

A friend of mine runs straight pipes on his gt3rs and although it sounds awesome its too loud for the street IMO .
From what I've heard the Akrapovic has too much drone inside the cabin .
So pick an exhaust with a great sound that is not overbearing . Its all about tone , not loudness .
Sport mufflers + center muffler bypass sound way better than stock mufflers + center muffler bypass .
Here is the tonemaster gt3 sport exhaust from Europipe :

Sharkwerks bypass for me too for sure! Just had it installed and was a little deflated and thought I made a mistake until I hit the sport button and 4k rpm.....the sound was so impressive. I agree with other posts here too, it is nice that if you need to keep quiet you can....to a certain degree.

The cargraphic Kit 3 does not come with a rear center muffler, so your Sharky bypass will work just fine.
