I am thinking about buying a MadDad(TM) Metal V2 Downpipe, it has a stock look, since I can not find much reviews on this downpipe. Currently I have a Greddy Evo 2 catback. Does those two fit? Will it be too louder to get any attention from cops??
Btw, I have a 02 sedan, and planning on stay with stock turbo, do I need to get uppipe? or does not matter that much for that pre-cat?
thx for all the input

 

I don't know about the compatibility between the MadDad downpipe and the Greddy catback, but the uppipe is a worthwhile install for any pre-2006 U.S.-market WRX. Getting rid of the pre-cat allows a somewhat quicker spool of the turbo (less restriction) and eliminates the possibility of turbo damage if the catalyst material degrades and sends particles into the turbo.

As for your choices, there are quite a few uppipes to choose from - some have a flex section like the stock uppipe while others offer a heat-retaining coating.

Cobb Tuning up-pipe, for sure. I just got the Accessport yesterday with a custom map from FLI and an up-pipe from Cobb. I got a 25% increase in power over all. The difference was night and day. I would highly recommend the up-pipe as well as the Accessport.
