+1 for Crucial. Thermal coated FTW! Cobb AP works just fine with divorced wastegate.
If I didn't go Crucial, I would've gone with either a MadDad (Carb certified) bellmouth, or the Cobb.

the "the carb certified" part on the maddad downpipes only refers to the cat itself. the entire downpipe is not legal. and unless you have paperwork stating that your oem cats are no longer efficient/blown you cannot change out your cat anyway. you would need 2 cats in the downpipe that are carb legal and have your oem cats signed off as inefficient for you to use it legally.

Here's a lil blurb from Daddy's post on WRXF.
More info on the site.

We haven't dropped an announcment in quite a while so we'll be making up for lost time over the course of this weekend with serveral of them. We'll start it all off with one of the biggest announcement we've every made. First off I'll ramble a little by saying a good portion of our exhaust parts we sell end up in California. Probably no surprise there since a lot of the sport compact scene is based there. Knowing that a large chunck of our business originates from there clearly has some influence on the products MadDad™ brings to market. Things like the MadDad Whisper for instance...which by the way passed a California Db test at 94.5 db on a WRX that was bone catless. But that's for another thread. So on with our announcement and you Cali boyz and girls rejoice.

APS works great!
Only problem is, their downpipe's are proprietary, meaning they only work with the APS systems...
I have the 3.5" TBE system...downpipe is awesome...cast iron bellmouth with a wastegate separator which attaches to a SS downpipe portion...I have two axlebacks to use...the stock cannon shooter and a retro-fitted Cobb....
Loud vs. Quiet...nice to have both...

i'm thinking about buying a helix catless but was wondering if anybody had trouble with boost creep or check engine lights. mods so far are accesport 2.0 hks cat-back and cobb intake. tia
Like many say, it does not really matter about the company, as long as its stainless steel. Titek and Megan Racing are affordable. As long as you got a quality company, your fine. No HKS.
