reposted to third gen JCW garage

I have a 2019 JCW LCI that I was thinking of having a catted downpipe installed. I have been told that catless is the way to go but I want to make sure I can pass emissions in IL. Could I do a catted downpipe with a JB4 burger tune? Anyone have any recommendations on a downpipe? My car has the pro exhaust and craven speed cold air intake. My goal is better sound for my daily driver. Any additional performance gains are just a bonus. I don't track the car, just enjoy some spirited driving.



Thank you!!!

 

What are your emissions check requirements? Do they plug into OBD and check for codes? Do they "sniffer" test? If your emissions check is a simple OBD plug and check, get the catless and a tune from @Lou@Prototype-R . The tune will turn off the OBD catalytic checks and you'll still pass emissions, AND you'll get a much better tune that the plug in module will give you.

Edit:
Also, that product you linked is for 2nd generation cars. You have a 3rd generation, so you'll need a different pipe.
