The MadDad(TM) Metal V2 downpipe is one of the most well received hi-flow metal substrate downpipes in the Subaru performance community. In this recent update, we've add an auxilury 02 sensor optimized for wideband/percision tuning. The MadDad Metal V2 downpipe is the only downpipe on the market that was explicitly designed to minimize or eliminate boost creep that many Subaru owners experience, in particular with STi models. The unique arrangement of a metal substrate cat closer to the turbo, but combined with a catless wastegate ensures fast boost control response.

The MadDad(TM) Metal V2 downpipe is the only downpipe with a 14 DAY MONEY BACK GAURANTEE....EVEN AFTER YOU INSTALL IT. See if any other performance brand will dare to match it.

5 of 5 Great downpipe August 17, 2013
Reviewer: Phil from Brockport, New York  
I have a 2011 WRX and decided to go stage 2. I took about a month and researched every available downpipe on the market and in the end I went with the MadDad downpipe. In my opinion the MadDad downpipe has the best design of all the available downpipes. Some others almost look the same, but they are not.

The wastegate tube is a true divorced design and is also catless and has no flex joint like some of the others. The hi-flow cat in the main tube also allows me to stay legal in my state, but also allows for great exhaust flow. Also, the auxiliary 02 sensor hole for use with a wideband sensor is a plus.

The fit, finish, and build quality is superb. Every weld was perfect and it bolted up without any issues.

After the install I flashed to stage 2 and gained 28HP and 25ft/lbs torque over my previous stage 1 tune. These gains are due to the superb design compared to others.

If you're looking for the best downpipe on the market for a good price, look no further and get a MadDad.

5 of 5 Great power and quality March 31, 2012
Reviewer: Patrick from LA, CA  
Had my eye on this DP since my last STI. Decided to finally go stage 2 and really love the performance. The shop tried to talk me into an Invidia - glad I went MD. Fit and finish are great. Doubt anyone will be fooled by the fake cat cover on the bottom - it looks too nice for stock!

Dyno numbers are highly variable so you can take these as reference - 2011 STI sedan - the baseline was 265 running COBB OTS stage 1 with AEM intake prior to the DP install. With the DP there are a number of runs over 300, but the cleanest ended up being 299.5. Same dyno ran an all stock 2011 that same week and it was 235.

Great power, sound and response.
