If you're looking to get more power from your turbocharged vehicle, then the downpipe is usually where most start. The factory downpipe is high restrictive, and Invidia addresses this issue with their Catted Downpie with the Divorced Wastegate option. This downpipe has been crafted from 304 stainless steel, and has a 3" piping diameter to allow the exhaust gasses to escape which improves throttle response. turbo lag, and you will see increases in both horsepower and torque.
The exhaust hangers have been welded into the stock location of this downpipe so you don't have to perform any further modifications to the body. Additionally, new hardware and gaskets will be provided to make for a ready installation.

2007 WRX - Free-flowing goodness

Was looking for a downpipe to pair with my HKS sport cat-back, and this fit the bill without breaking the bank. Top-quality shiny SS right of the box. Fitment is perfect - I mean so perfect I was able to line it up on the turbo studs and attach the mid-pipe by myself, with no 2nd pair of hands needed. Intercooler removal isn't required, but it makes thing easier. Notes: 1) You obviously need an ECU tune with this upgrade. 2)You will need to trim your OEM turbo heat shield or go with an aftermarket one. I trimmed mine, templates available online. 3)Easiest way to line everything up, loosen all the exhaust connections without disconnecting (except the downpipe you're removing), then tighten up working from the turbo back. No exhaust leaks, no boost leaks, nice rumble that turns into the classic boxer snarl at WOT. A Cobb Stage 2 WRX is a happy WRX.

This review is for the now discontinued catless bellmouth version. A couple years ago I ordered the Invidia 3" Bellmouth Catless DP for my 02 wrx wagon after the assumed ebay special that came on the car cracked around the flange and sounded like a truck. The fitment was great, relatively easy to install (if you aren't afraid to get dirty and are somewhat handy), and to this day still looks like new! It really unlocked the rumble paired with my UEL 3-bolt headers/UP and Greddy EVO2 cat-back, you can hear the turbo spool even on the basemap, and it turns heads every day. Even being catless when I do get stopped, it wasn't for the exhaust (except when I had a pre-turbo leak) and they usually compliment how it sounds after a "it's a bit loud but eh". Can't speak entirely for the Divorced/Catted version, but overall I love it. The catted version should be a bit more quiet and "legal", attract less attention from the law, and help prevent overboost/excessive spool when internally gated on the td04.
Quality That Lasts

Bought a Catted Down pipe to keep my car somewhat legal with emissions. This was the cheapest downpipe available at the time, and I was on a budget. I've now owned the is for 3 years, and have very few complaints. I have not had a single regret about this down pipe. It gives the car an more power and reduces the traditional choke point the stock exhaust had. Recently got the car tuned by bren tuning in Mass. They were able to get 255 whp (mustang dyno) out of my car with a Typhoon intake, this downpipe and megan 3" exhaust. My only complaint is when I installed my catless up pipe I had to remove the downpipe to get to the turbo. The bottom nuts are nearly impossible to tighten without specialized tools (or smaller hands) This is more of a design flaw of the car than the product.

Please keep in mind that you will want to have an exhaust appointment already made when you start to put this downpipe on... The sound bring out the MONSTER in your Subaru. I switched out the stock system with new headers and matched it up with this Catted, Divorced Stainless 3" beauty. All along with a turbocharger upgrade at the same time... I am the LOUDEST car around town. Deep, throaty at idle, like a BEAST! On throttle. Too much for my taste but I love it... I'll upload a video for your 2.5 turbo Subaru enjoyment. I have an exhaust appointment in two weeks and I've added a electric dump cutout so I can have this sound with a flip of a switch! Highly suggested. I'm starting to get the wrong heat bright to me.
