I see its just about the only system which has two independent exhaust boxes and no central cross over pipe, what does this mean performance wise etc ?? & if all the other systems have a central cross over pipe or silencer that must be better right ??

 

i believe it is more of a weight savings... and since it is in 2 pieces it can absorb / take in more shakes n rattles tahn a single piece.. but i personally think it's more onthe weight savings than anything at all..

 

StephenTI, had the Cargraphic Super Sound export exhaust on his car, when he switched to the Techart race, he said he noticed the car was producing less boost. In looking at both exhausts, the cat on the cargraphic is larger which would seem to me to indicate the more turbo gases are pushed through?? Anyway, just passing along info. StephenTI's car is high HP, so the loss he experienced would be more prevalent than in a stock car... Overall though, Cargraphic is best and techart 2nd imo

Lou is right... Techart seemed to produce slightly less boost than the Cargrahic. But, I do believe they have a racing version that's bigger in diameter... check with Neil. And although exhaust tone is subjective, I still think Techart is one of the best sounding exhausts in terms of refinement with aggression. Cargraphic is more raspy. Fabspeed is simply raw.

And many exhausts make the 180deg turn in the muffler, even though externally, they may not look two piece.

 

Do you still have your Techart on the car ? I know Endra ran his for 2 years

 

Started with Cargraphic, sold it for Techart, the sold that for Fabspeed loud.

 

and which latest longer on your car the Cargraphic or the Techart ?

 

I had the Cargraphic longer... but, I prefer the Techart over it purely because of the way it sounds. In the end, I went with Fabspeed for all-out-power.

 

I was/am seeing 1.3 Bar Upsolute stage 2 with my highly modded OEM Exhaust and Cargraphic Export (too) Loud (for me), what were you limited to with the Techart Stephen ?

 

Don't mean to speak for stephen, but, since it was my techart exhaust that was originally meant for my creashed 04 turbo, i know the answer. Stephen was seeing .1 bar less than what he saw with the Cargraphic.. It was the 60mm techart race exhaust... Techart does make a 70mm version which is for higher hp applications and may make up the .1 bar boost loss..

Lou, you can speak for me anytime!

 

1.3BAR? How old is your programming? How are you able to see 1.3 with Upsolute?

I've adjusted my wastegates continuesly to hone in on the limits of my setup, which puts me at just under 1.2BAR. If I push it beyond, OCCASSIONALLY, I will hit the limits. (When that happens, sometimes, boost will be lower for a couple runs, and go back to full boost).

I've always thought that the limit resides in airflow as opposed to boost. Perhaps somehow, my turbos (Kevin stage ii with all the goodies) are following more airflow at lower boost limits compared to your similar setup, thus, resulting us to run different boost limits. Just wondering out loud...

 

Stephen, we have Upsolute Stage 1, which was 1.0/1.1 Bar and I went back for Upsolute stage 2 in March 04 which consistently reads 1.3 Bar, apart from Bailey's, the Exhaust and a fully cut back airbox thats it for my engine mods. I have now done about 6,000 miles on Stage 2 without the slightest problem.

 

When I had my TechArt, I was also running GIAC stage2 ECU in the car along with DVs and TechArt sport-filter. I can constantly hit 1.2Bar all the time, with no problem.

With the 100 octane gas, I've seen it went to 1.3Bar. (not all the time)

 

I've got the Stage II Upsolute with Kevin's billet/port/polished/coated turbos. Performance-wise, it's similar to Evo IV/GT. However, for whatever reason, my setup doesn't like boosting 1.2BAR and beyond without some kind of momentary boost limiter (just one or two runs) cutting in. Sucks, 'cause I know it's got more to give.
