Default wanted: Sources for pre made subaru specific High Flow Cat pipes ( CATALYTIC )

Im looking for sources for high flow cat pipes that will mate up to the stock exhaust. Specifically 2.5l engines. The option of choosing 2 1/4 diameter and 2.5 diameter would be great.

So far Ive been looking at the TWE pipe for 239 at http://www.techworkseng.com/prod03.htm but the price seems high.

Does random tech have some? Or cobb?

Im also contemplating the Catco universal items.

go to a muffler shop, tell them you need a pipe made for Track use only(if you want no cats), or tell them you need a straight pipe with a high flow cat in it... they should make it for less than half the price of the Random Tech or TWE...

having a test pipe made would be pretty cheap, but a good highflow cat is almost $300 itself . . . so passing emmissions isn't cheap. I decided to get a cat because I wanted to be mostly legal and pass emmissions.

get a test pipe, then when it comes time for emmisions testing just swap the stock cat section back on... it's easy enough to do, and IMHO worth saving $200...

$300???? Oh my, where do you buy parts from?
Summit sells Catco cats for $59.99 and they flow just as well as any cat you'll find.

Cheap enough to run on any budget.

Question info

Can someone please state what model cat from Summit Racing and/or Catco will fit the 2.5RS? That would help!

I'm betting that none of you purchased a Cat converter from them for the 2.5RS but some other car.

Kevin: the catco hiflow cat is a universal type that just gets welding into piping. It is not made to fit any particular car. you just bring it to a muffler shop and ask them to make a pipe with a hiflow cat in it. it cost me like $75. i had them make a track pipe at the same time with no cat as well so i got both for $100.

what about CELs with universal cats? the reason i would get a cobb or a random tech is because they dont have CELs right? i'm thinking about getting a high flow cat and i was about to spend $300+ but now i am reconsidering

you just buy the one with the correct size piping. if you are exhaust is 2.5" then you buy the matching CAT.

Cool thanks I saw some Catco coverters on summitracing.com and it ask you how long you want the cat to be, thats why I asked.

I just have to ask did you have to buy and pay to have the 02 sensor bungs put on? Thanks
