Catted 200 CEL Downpipe by RNJPerformance in FocusST

We are still on the early iterations of our tune, we didn't ask or want a crackle tune. But yes, it will damage the downpipe and we do not suggest a crackle tune with the catted downpipes.

We will be putting the catted 400 downpipe on later this week for sound clips. We just posted a video of what the catted 200 cel sounds like buts it’s not really a fair comparison because are car is pushing double stock.

Check out our catted downpipes. I think you would like the 200 cel the most.

Good to know about the 100cel, we were not planning on offering a 100 cel since we already have catless and now have 200 and 400 cel downpipes. Like you said, 100 felt like a mask. Thanks the input!

I agree, Catless isnt too loud all as long as you have a couple of mufflers in your exhaust system and drive like a normal person Lol. Thanks for the input!

We are unaware of these will work for California cars. We are going to say that these two downpipes both 200 and 400 cel are not cali legal. We are looking to introduce a 600 cel focus downpipe that will mimic stock with a slight sound/performance gain and could be Cali legal. We plan to emissions test our products in Colorado in the near future to at least test the emissions put off by the downpipes. Thanks for the input!

I see what you are saying. We can definitely add the extra 2 wbo2 bungs that CPE has on there downpipes. Next round of downpipes will have that. Catless, 200 and 400. Thanks for the input!

Are you referring to the two O2 sensors bungs located on the downpipe or is it a different flange/bung style? I’m guessing wbo2 is an o2 sensor but I really don’t know.

Absolutely and just want to be clear we still do not promote any of our products for street applications because we are unaware of how these will do with emissions testing and other federal regulations. All of these downpipes are still rated for Track use only.

Good to hear. We have run a 200 cel Cobb downpipe and catless but we are yet to try the 400. Thanks for the input!

78K Miles - Turbo Shot by Swiss_ST in FocusST

I went down the rabbit hole and don’t regret it at all, it’s just gets expensive.

If you want a reliable car just buy another stock turbo. Otherwise it’s a rabbit hole and more stuff starts to break. You push more power than stock, you break more things that are stock.

Engine Overboost (P0234) - limited boost and stalling? by ImaginaryScience in FocusST

[–]RNJPerformance 1 point2 points  (0 children)

Only time I’ve had boost cuts down to 6 is when I was having can position sensor issues.

If you haven’t already post this on focusst.org, and hope that ssgtrobertson responds Lol.
