which high flow catco cat do i get? and what length?

[Mugen13]

i'm looking on summit racing and there are a lot of different lengths and models of high flow cats for 2.5in. I need this to replace the dummy cat b/c i have a HS header and custom 2.5in exhaust and its too loud and ricey for my taste.

but which do i get?1) 14 in. part # CTO-6906 2)12inches part #CTO-6806 3) 14inches part # 6006 4) 16 1/2 inches CTO-2906 5) 16 1/2 in. CTO-2606

Keep in mind that these may outflow the stockers, but they're NOT "high-flow" converters.

Length is not as important as diameter. Stick with something similar to your stocker.

i was looking on past threads and ppl recommend high flow cats from summit, but it doesn't seem like they sell any.

Do they just not say that they are high flow cats or what?

I picked up a 3" catco cat like the one HT sells for 50 bucks shipped. Had them welded with flanges from an old exhaust for 45. Picked up the catco from ebay and that was price shipped. In retrospect, it'd be easier to go with the one from HT since it was a pain in the butt trying to find the flanges.
