SV6 LFX High Flow Cats?

[niko99]

Hi, I have a LFX sv6 auto thats already been MAF tuned with 185rwkw (everything stock) I've been wanting to make that bit more power and be a little louder so I looked into getting some high flow cats. Will they be worth it? and How will it affect the sound of my car on the stock system?

Wouldn't plan on changing cats unless you're planning to get some kind of retune soon, pretty sure they will bring up a code. Changing anything in the cat back should be fine though.
