Well, i've been through a couple of exhausts in the past couple months and thought i would share my experience up to now

I started with a set of Tubi's w/stock cats, sounded good....but not great (at least for me) In my hunt for a bit of grunt i bought a set of Cargraphic mufflers and a set of Gundo's, as well as a set of AWE cats & a the Fabspeed X-Pipe 200 cel cats. Here's my quick 12 cents;

btw 'scoring' is based on my own personal experience, nothing scientific....

My car is a 2006 C4S w/X51 headers


Tubi Mufflers - I found the sound to be a bit on the high note, sounded good, but not what i was looking for. On a cold morning they did sound really nice, but as they warmed up I felt like i was driving an Italian car (i guess the are made in Italy ) - Didn't feel any power gains of any sort. For me, these were a 7 out of 10, nothing wrong, just not for me

Cargraphic Mufflers - Holy Crap......sounds freakin amazing.....i can't say enough good things about them, from build quality to the phenomenal sound that comes out of them. Sounds kind of like my 993...sweet sweet sound - Didn't feel any power gains but didn't care, these are an 11 out of 10 for me

Gundo's - Sounds amazing, I really like the sound and can't believe this noise comes from a set of stock cans with a 2" pipe added. I would have kept them, but couldn't resist the Cargraphics. No power gains, but these score a 10 out of 10 for me

AWE Cats - Changed the sound of my car, sportier, not lower just louder by maybe 10/20%, loved them, went on really easily, and felt a bit of a power gain,these sounded great with the Gundo's but they complemented my Cargraphics very very very well. I'd give these a 9 out of 10

Fabspeed X-Pipe - Changed the sound of my car, again sportier, not lower, just louder by maybe 20%, almost like the AWE Cats (but didn't sound as great) - Didn't feel any power gain whatsoever, which surpised me a bit, not sure why. I'd give these ones 6 out of 10

So unfortuately I installed the AWE cats before the Fabspeed's, I sold the AWE cats to a friend of mine who wanted to try them and now he loves them, so my current setup is the Cargraphic Mufflers w/the Fabspeed X-Pipe which does sound good, no drone and can be pretty tame as long as you don't open it. I will be on the hunt again for some AWE cats as i really did like them

Lesson learned---.........Cargraphic's & AWE Cats.......but that's just my taste

 

Wooo hooo!
Awesome self-inflicted Guinea-pigging, my friend! Your subjective review is right inline with what I expected, so I am surprised you sold the AWE's before trying the FS cats. AWE are the ticket, if I come across a set I'll grab 'em for you.

As for the cans, the Gundo Hack is a 10/10 and Cargraphic an 11/10, pretty amazing, eh? When you consider the Gundo's can be done for $100-$150 vs. $1,700 for the Cargraphics, it's even more impressive.

Have you installed the EVOMS CAI? That'll change the sound (for the better) a bit, too.

My neighbors love me......luckily i have a guy with 3 Harley's who live across the street....so he still qualifies as the 'loud' guy on the street

Hopefully he doesn't move,,,,,otherwise i'll become "That guy"

 

You're right on the money.....the Gundo's are great, again for a set of stock can and a 2" pipe how can you go wrong???

I was VERY lucky, as I picked up both a set of Gundo's & the Cargraphic's from a fellow member for a freakin amazing price, he must have felt sorry for me

I did install the Evoms CAI, i really like it and it added a nice touch, you can really hear it sucking in the air at high RPM's,,,but honestly the Cargraphics drown out everything with its glorious sound

 

Either of you guys still have the Gundos and want to sell?

 

PM sent

 

Sometimes its the journey... not the destination.

Shoulda tried the tubi's mated to the fabspeed x-pipe... that's what I have and it sounds amazing. Of course, I prefer the higher pitched exhaust sound.

 

There's a guy here in the UK with a pair of AWE cats for sale on a local Porsche forum:

Shipping is not expensive to the US so maybe you could cut a deal?

 

I'll buy the Gundo's.
Pm me if they're still available.

 

The new Tubi for 997.2 comes with crosspipe.
Guess I like a high pitch. My Tubi definately sounds better after it has warmed up.

 

I love my Tubis...

 

Gundo's just got more expensive, I think.

+1 for Tubi....love the sound! curious about adding the awe cats and/or the x51 headers but i dont want it to get too loud

 

I'm running the Fabspeed x-pipe and mufflers, equal length headers and the Fabspeed CF Maxflo Competition Air intake (new) and it sounds outstanding. Very hard edge at high RPM/WOT. Couldn't be happier, though, from what I've read, I'm glad I have never heard the CarGraphic up close.
What is surprising is how the sound changes for the better (louder and edgier) as the car warms up. It takes quite some time for the full sound to evidence itself.
