looking for any after market dp preferably catless but either is fine. In california but will pay for shipping if needed.

I had a catless downpipe for a few months until i decided to go with a sport cat downpipe assuming the cel would go away. I cleared the cel lights on my sct tuner but a few days later it came back. Ive heard if i get a new O2 sensor it might fix it but just wanted some more info before i buy one.

I was wondering if I purchased ATP Turbo GT3071R if it would connect up to my cobb downpipe. Just making sure that I'm not going to have to do any fab work because I'm just working out of my garage. Thanks. My car is a 2014 Ford focus st.

Hey guys, I have a 16’ focus st. Want a catless downpipe. Most of the ones I find are just the test pipe itself, on the engine the pipe is off the headers, will just a pipe bolt onto the stock headers or should I go for headers with pipe together? Tia

I know for the most part all the catless downpipes are essentially the same except for maybe build quality and one or two other small details so i have been trying to look on the cheaper...

How hard is it, (if possible at all) to replace the bank 1 sensor 1 mainstream o2 sensor on the Focus st? Really don't feel like removing the downpipes to take the o2 sensor off and don't really have the time to.

Hello, I just bought a 2016 Focus ST, I love in California and since moving Isn’t an option for now does anyone know if it is bad to do a catless DP and resonator delete? Could this hurt the engine in any way? I plan on doing minor upgrades like IC and intake but I don’t want a loud exhaust.
