Default High flow cat advice anyone ???

Anyone feel like giving me a recommendation for a set of High Flow Cats for my car? I am currently running FLP's longtube headers with X pipe and corsa indy's. Car has Patriot cnc'd LS6(243 casting) heads with Patriot gold dual springs and stainless Ferrea valves 2.02/1.57, Speed Inc SI6 cam Comp Cam(.595/.610 232/240 110lsa), Comp 7.40 chromoly pushrods, SLP heavy duty oil pump and double roller timing chain, SLP underdrive pulley(same as powerbond), MSD 8.5mm wires, SVO 30lb injectors

Dont wont to lose the sound and power but could certainly due without the raw fumes so i guess i will have to comprimise ?? Any thoughts fellas ?? If anyone has a similar setup with some soundclips with cats installed that would be great.
Joe

We carry Random Technology Hi-Flow Cats. They are quality made and stainless steel. They are available in Ceramic ($419.99) and Metallic ($496.99) elements. They have a 3" inlet and 3" outlet, with a 4" body. Let me know if you're interested.

If u want to go cheaper than Magnaflow Spun cat, bullet style ur choice of Inlet/outlet choice and just weld it, they r metal mesh inside and flows over 540 Cfm each, u need 2.4CFM for every HP, so i assume ur's is 500 CHP atleast, so its pretty darn close.

Or Random tech are tested n proven the best and flow really good, dont know how much cfm they flow but i have seen them in person and they r quality piece except price tag.

The above vendor is new and offering great prices, to me i usually prefer forum vendor as we r here bcos of them.

I went with Eastern Catalytic 3" 200 cell metal matrix high flow bullet cats on my custom 3 exhaust system.

They work great, are made by a very reputable manufacturer, and you can probably get them for a price in the neighborhood of $150 each.

PM me for details, since the vendor I bought from does not advertise here.

Yeah dyno says 452 to the rear so i need something to flow well. Will the cats drown out my raspy headers and cam ? Also will these cats take care of the fumes that i am sucking in ??

Oh it is not to bad, but then again I like the smell of race gas too. . I run a 4:1 93:100 octane mix with LTs.s and no mufflers.


My car is a track car.
