my understanding is that with the CARB cert... visual inspection consists of matching up the stamp with the cert #. So RT's would in fact pass the visual inspection. No?

 

They would never be able to get to them to match up the numbers.. But even RT's web-site says they are for off-road use on Calif OBDII cars and to matters worse they say they're 50 state certified legal..... Oh, I love my home state!!!. Doesn't stop me.

 

It is probably because the scales for hp and torque are different on each side of the graph

 

I am going for a dyno in the AM and he will re-print those numbers scaled properly...

 

just got off the phone with danny @ TSI-

they said the RT cats are making the car go extremely lean for some reason, they really dont know how different they are compared to the straight pipes they made for my car---- they are going to flow bench the RT pipes sometime this week..

 

What sort of problems does the "extremely lean" condition cause? I was seriously considering the RT Cats and am anxious to hear what Danny and the guys at TS have to say following their bench test.

Anyone out there with the RT cats already installed having any problems due to running "lean"? If so, how did you take care of it?

Thanks

 

Adam, any pricing on the Ultimate Racing products?

 

PM'd you!

 

will the crawford cats trigger a CEL?, ive been considering them for my first performance mod.

 

No high flow cats will trigger a CEL, nor will TEST PIPES if you install everything correctly and dont mess up the O2 sensors.

The RT Cats are Carb Legal, but still with any cat it is illigal to change them before 50,000 miles or unless you have some damage to the cat, (which you have because the z rides so low rite?

RT High Flows $500

 

how would a test pipe not throw a CEL? the after cat 02 sensor would realize there was a problem and throw a light, unless you mod the sensor of course.

 

so far i havent heard of any ones test pipes throwing a CEL or anything. nor any high flow cats...

but, no one said anything about test pipes running lean...

odd innit?

 

Exactly..for reason this car just does not seem affected by the test pipes.

 

well, the high flow cats and Y pipe went in today...just in time for the snow, so no dynos today or tomorrow (as I could not even get my car home today in the snow......had to leave it at a shopping center). Fit and finish was perfect.

Really nice sound though, no performance posts till the roads clear here next week.

 

look forward to that!

 

RT Cats, not lean here, exhaust was 80% open when flashed though, bung pre cat for readings, not tail pipe.

Out....

 

Anyone know how the RTs would sound with and HKS catback exhaust?

 

Dec 2003. Holy.... Over 13 years ago waking a dead thread. Is this a record?

 

Just like most of the other available HFC's with that exhaust. Pretty much like a pair of raspy 3 cylinders, almost Cessna sounding.
