I've got the 70mm invidia as well, threw a CEL after a about 40 miles, but after installing the antifoulers, i've had zero problems

 

Just ordered an Invidia 70mm test pipe to try out. Crossing my fingers that the defouler trick will work. Just need the snow to melt now!

 

I'm running the T1R 70mm Sparrow exhaust w/ TP and have not had any problems after 5 days and about 200 miles.

 

i have an 06 with the berk tp and i throw a cell. sucks

 

I got the T1R 70R-EM exhaust with a T1R 70mm test-pipe. No cel so far, its been about a week.

 

So, two people have had success with T1R 70mm TP without mods and no CEL on MY 06+

Good to know

 

so which test pipe setup is best for a MY 06+? given the CELs on the berk test pipe, an invidia with some antifoulers seems like the best bet.

 

Well Ill be goin the anti-fouler route on my 70mm T1R sometime this week, Ill keep ya posted

 

Finally got my invidia test pipe and single exhaust installed last weekend. bought a pre-made stand off for the O2 sensor when I got the parts. So far no CEL after a week and 400+ miles. Car almost sounds like a bike now, don't think I'm ever going to get tired of that sound!

 

i think with either test pipe you run the risk of a CEL. just get whatever brand/size you want, if you throw a CEL, add some antifoulers and you should be good to go. given how well tuned the s2000 is in general, this is really the best bang for the buck mod you're gonna get.
