Random Tech's or .......
 

Whats the next best flowing cat and how much? What the best price for Random tech? It seems that i saw RT for 254 a pair somewhere recently but can't seem to find it. The best i've found is 155 a piece. Is there anything cheaper that is close to the flow of the RT's.

Thanks
Jon

Carsound cats (aka Magnaflow cats). Second best flowing cats out there.
A pair on e-bay for $110 shipped !

$155/per is an amazing price! Buy them NOW!! That's for the 7000 series metal matrix right? I paid 220/per and that was the best I could find. Those magnaflows are good too but they flow 200 cfm less than the RTs.
Oxidizr on here developed a new high flow cat not sure on $ tho...

You know Random Tech offer like 5 different models of CAT all in many different sizes.

Personally the best ones to go for are 7000 Series Metal Matrix ones (LG use them on their catted X-pipe for the C5). Magnaflow are supposed to bringing someout like this soon.

Failing that Magnaflow Carsound CATS are pretty decent and would work well on a bolt on cammed LS1.

If you plan on FI and high boost then the 7000's Metal Matrix ones would be the route I'd go.

What part number would I be looking for on the carsounds for a 2.5 in/out for my car.

I have the magnaflow/carsound 3" in-out, $50 ebay cats on my car, and love them.

Oxidizr developed some new ones that are supossed to be badass, even though they cost a bit more.

Here is a page with a system that he did for a guy. Those cats are the ones just released. PM him or somthing....
