High Flow cats?

We have 2 cats in our exhaust right? Is there anywhere I can buy replacement High Flow Cats from the internet? And if there is are they easy to install, and will I get a CEL? Also how much gains in HP at the wheels should I expect to see. Like maybe 2-4? Will there be any difference in sound? Thanks :D
 
BlackMSP - why don't you either wait for our full turbo-back or even down-pipe back exhaust sytem? It comes with a hi-flow cat section which replaces the 2 stock cats :)
 
tru.. I shud huh.. its just really hard to wait and cats would be so much cheaper... bleh i duno its a hard choice

So Ion your saying that you are coming out with a turbo back exhaust system with hi flow cat section and this exhasut system will pass the emissions test.
 
mikeeeee - the MSP has the following parts after the turbo:

(a) casted dump piece with a nasty nasty bend - not good for performance.
(b) intermediate "down-pipe" between the casted dump-piece and the 2 cats.
(c) cat section containing 2 cat converters.
(d) mid-pipe section (connects 2 cats to muffler section)
(e) muffler section.

Our turbo-back replaces parts A->E. Our down-pipe back section replaces everything from B->E.

BlackMSP - by doing more pieces @ the same time, you save yourself down-time, labor and also you get more performance gains. Pieces ment to bolt to stock exhaust components will not allow you to maximize performance due to the restrictive stock pipe size.

STLBLKMSP - yes it will pass both US Federal as well as Canadian Federal emission test standards. Our WRX turbo-backs that utilize the same hi-flow cat we intend to use for the MSP passed even the requirements for the CARB sniff test (not the visual). Mind you the stock WRX has 3 cats from factory, we deleted all 3 and put 1 hiflow in place :)

mikeeeee - our "down-pipe" is both piece (A) and (B) together as 1-piece. You'd have to replace your sell the down-pipe you have now, and have the cats modified to fit our "down-pipe".
 
mspeedpro - The full stainless turbo-back will be ~$1049US, which includes a hi-flow cat. The rear section you can have optionally in CF, this is a $350US option. For the down-pipe back system, it'll probaby run $749US or so in the full stainless version.
