You're welcome to check out my setup as I'm close by. AR catless downpipes, Borla catless midpipes, and Borla cat back (single muffler). Was too loud for me, so I added a Magnaflow muffler to the midpipes.

Went this route so I wouldn't have to cut the stock system. Hopefully I'll pass emissions if I bolt the stock midpipes and muffler back on.

ya i would like that.. Im thinking about just doing magnaflow mufflers and nothing else.. would this even sound good? maybe take out the cats?

magnaflow mufflers itself will make a very slight different but not very noticeable compared to stock. I think if you go this route with the magnaflow muffler also delete the secondary cats and you will be good to go. Don't forget that the magnaflow mufflers do have a little drone. But I love my magnaflow muffler but want to make my car slightly louder, it is still too quiet for me

got any audio clips? and when you say Drone do you mean 1992 honda civic straight piped sound? i hate that...

and also will i still pass emissions if i need to with deleting the second cats?

Any updates on what you did?

Depends. The O2 sensors are in the primary cats so you could be good with just swapping in the stock downpipes for emission. But if you live in California for example you might need all cats.

Before deleting your secondaries, try your primaries. I have magnaflow mufflers and it completely changed the sound when I put the catless downpipes in.

Have not done anything yet im getting the catless DPs first (on order) and im going to see what that sounds like first.

I'm running magnaflow mufflers in place of my stock muffler and have a resonator delete, which the coupes dont have anyway. Its a completely different sound from stock. There are videos around of the setup.
