Default Single highflow catpipe for 2.5? anyone make these?

Im looking for a single highflow cat pipe. needing it for rally. I assume if some company makes these it would be cheaper or as cheap as buying a high flow cat and having a custom pipe made with flanges.
thanks
Aaron

The stock cats are not 2 equal cats. One is a precat and the other the primary and each filters out different emissions. A single high flow cat replaces both cats functions. Just buy a universal fit like Catco brand (available from Summit racing) and have it welded in place by an exhaust shop or spend 3-4 times that money and buy a Random Tech/Cobb unit that bolts in.

Check with Dale at Teaguesauto.com . I just picked up a Stromung hi-flow cat. It is designed to fit between the stock headers and midpipe. No modifications required. I am now running Borla headers followed buy the Stromung Cat, midpipe and dual tip exhaust.

sorry, I re-read your post (before you changed it ) and wasn't sure which you meant. Either way, your options are a couple hundred+ for a bolt-on piece, or ~$80 + install at a muffler shop. take your pick.

I don't know if there even still selling it. All it was was a random tech unit with cobb's name on it.

I had a track pipe made for $100 at a local muffler shop, but I had to install it myself, no biggie.. I had 02 sensor bungs welded into it and I have yet to receive a CEL. Don't let anyone fool you, a straightpipe will always flow better than a cat..

Default cats required

JoeFocker20...
we in rallying are required to carry one cat. catless exhaust systems are now illegal per SCCA.

www.techworkseng.com has a high flow cat section that bolts up to the stock locations.

Located in Calgary, Alberta. Nice guys to boot. I just ordered their header, which is tuned / equal length and ends at the stock location too! Nice stuff.

Random Tech - Yes, its pricey. (got mine for 338 shipped from Nino's) Very nice peice, though. Everytime I show someone my exhaust, they are like.."that's the cat?" Its very light and has a 2yr warranty.

Thank you everyone for the replies. i think i am going to go with the random tech super hi flo cat pipe. The cat is super duper small and the thing is nice maybe too nice for rallying. ill just shield it well.
