catback or highflow cat?
I was thinking that maybe a high flow cat would be the next best exhaust system upgrade after the dp. What do you guys think? Simply putting on an aftermarket cat back will free up exhaust gases being slowed down by the stock setup, but a high flow cat will the gases through quicker to begin with.
Oh, and I want to keep this one legal, so no midpipes.
thanks

Catback for sure. Unless your Cat is really plugged up getting a Hi Flow cat won't be as drastic.

Thumbs up
I say catback first also. There's the added appeal of being able to see it when you're outside the 7

You'll probably end up doing both sooner or later.

If you have a lot of miles on the cat, I would do the hi-flo first. I've never heard of a catback getting clogged and causing boost problems.
