I bought from 2M Fabrications. Cheapest you'll ever find. No CEL after several thousand miles with their provided o2 spacers. YMMV though as I have seen some people say they've had a CEL.You can find a write-up I did linked below for everything you'll need.

I am finishing up the install on my cat delet pipes did your 02 spacers have the mini cats in them? Mine where just 90° spacers you could see right through.

No the supplied spacers are not mini cats. They are simply just angled spacers. I haven't had a CEL come on once yet with them.

The sound is great. Cold starts are *very* loud and usually scares anyone within 50 feet when it turns on. Once it's warmed up it's actually pretty tame (mine is cat and muffler delete). From inside the car it's not that loud even at WOT but from outside it sounds good.

I tried just a regular muffler delete keeping the stock cats and it was just way too quiet. Deleting the cats or getting sport cats are a must on this car in my opinion.

Nice to know. I just spent a hefty penny on high flow cats. I didn’t know there was an option to do cat deletes or even high flow cats that wouldn’t trigger a CEL.

Can you tell me what exactly is a regular muffler delete? who makes the pipes in order to do that and how much noise did the muffler delete with stock cats still on (that was way to quiet) changed compared to with muffler in place?

So my car came with an AWE catback on it already when I bought it. For me, I just went to my local muffler shop and had them fab up and weld in a set of pipes that basically took the place of the mufflers from the AWE exhaust.

If you have the stock exhaust, your local muffler shop and likely still do a muffler delete. I don't know of any vendors off the top of my head who sell muffler deletes that replace the stock system. The noise difference from no muffler with cats vs mufflers with cats is pretty noticeable. You'll definitely be happier. I just like my cars extremely loud so it wasn't good enough for me.

What is the exhaust smell without cats? Suspect pretty foul.
