Hi all. Was hoping to get AMS High Flow cat but can’t find it anywhere now. I ended up buying Invidia High Flow cat with downpipe (haven’t installed yet and could possible lose 20% restocking fee) however I can’t help wondering if I’d be better off finding a different high flow cat and going with AMS downpipe or Tomei downpipe instead as Invidia downpipe doesn’t come with a turbo outlet upgrade. I could upgrade with Megan Racing turbo outlet if I wanted to later if I kept the one piece Invidia but I’m also a little lost on what parts are better and if this Invidia one piece high flow cat/ downpipe is a good part or not. Would appreciate any advice. Thank you.

 

Get an ETS down pipe and ETS race pipe with the GESI cat.

 

I wish. Trying to avoid $800 high flow cat though. Any other ideas or think what I’m planning is okay
