I'm upgrading to Kevin's Stage 1 turbos and 100 cell cats. Kevin recommends getting a free flow exhaust system. In general, I prefer my car to be quieter for daily driving so I need:

- High quality
- free flowing (at least enough to provide full potential of the Stage 1 turbos at the track on 100 octane gas)
- As quiet as possible

I had the Fabspeed muffler bypasses and didn't like them much; too much resonance around 2500 RPM and I didn't much care for the Criscraft boat sound at idle.

From searching around it seems the best quality systems are from Cargraphic, Techart and Fabspeed. Kevin thinks Fabspeed is the loudest of these so that leaves Cargraphic vs. Techart. Which is quieter?

Please let me know your opinions (or facts if you happen to have some sound measurements ).

Finally, where should I get them?

Thanks.

I think that both cargraphic and techart have a TUEV approved version of their exhaust. A TUEV approved exhaust can not be loud at all, so I would make the decision on price or availability rather than quietness.

Personally I would take the Cargraphic :-)

Steve suggested RSR's made by Sun at p-car.com. Hope to put mine on tomorrow night.
Toby used to run Cargraphics and noted they were loud but performed well.
The AWE tuning site has hp/tq graphs and videos for their sweet (but really expensive) muffler system

I have Billy Boat mufflers sitting in the garage gathering dust here as well.

I've heard that Ruf uses Techart mufflers.....but don't know if Ruf modifies them or just rebadges them. Anybody with any insight?

That AWE system isn't so expensive when you consider you are getting cats and headers.

Have a Techart exhaust with 100 cell cats on mine, its not over loud, unless really giving it some.

There are many re-badged Techart and Cargraphics (Phoenix is the manufacturer, which is owned by Cargraphic) mufflers sold by various tuning companies. Both are very good.

Myself and the good doctor (in ST. Paul) both had the Fabspeed Maxflow Mufflers and they are
very quiet/flow well/good quality. They must be the ones that require their own tips (this
is the latest version). The tips slip on and have a black sleeve. I will try to post picture.

Several people said they'd take the Cargraphic over the Techart; can you tell my why you like the Cargraphic? Thx.

I went from stock to Fabspeed mufflers to RSR mufflers. Fabspeeds were barely louder than stock. RSR are significantly louder, but not to the point of being obnoxious.

Woodster

My RSR's were very loud (and I do not think Robin's "manufacturing process" is very exacting),
But as the thread requested, if you want:
High quality
free flowing
as quiet as possible,
Then these fabspeeds fit the bill and are less expensive than the Techart, Cargraphics, etc.

Is it that for Kevin's Stage 1, the Fabspeed Bypasses won't work or they do work and you just perfer mufflers instead?

Acropora

Just put in RSR mufflers w/ fabspeed cat bypasses already in place. Very nice tone, but really loud, certainly much louder than stock, just as Robin had predicted.

I just didn't like how they sounded... that was with stock turbos.

i can not say enough good things about the sound of the cargraphic mufflers (stock turbos and stock cats). Im not smart enough to know if they allow less backpressure, but they sound very agressive when cold, but not like a motorboat. Also they sing when over 5k rpm and are much louder than stock. While they dont sound as good as my varioram 993c2, people have walked up to me and asked about the mufflers b/c they knew they were not the stock ones. I have not heard the techart, but i have a feeling they are similar.
