I personally run a tabby cat and then a siamese cat but that's just me!

Kidding! I want to go true duals on my truck AT SOME POINT and am having trouble picking which cat to go with... Are the flow master universal cats going to be high flow compared to stock on my 302?

 

Any aftermarket converter is high-flow compared to the factory converters. I used a Magnaflow 59929 on my old 1992 F350 w/5.8L engine.

Personally I see no reason to run duals, why pay for two of everything for zero benefit other than a lighter wallet and bragging rights.

 

I used a pair of the 3 inch 200 series on a Supercharged Jag a few years back and they were excellent. Flowed really well, so my guess is that they'd flow way better then the stock 302's cat.

 

Personally, when I drive a V8, I like to hear it. That's why my 460 has 2.25 duals all the way back.

Its because I'm young and dumb.

 

Doesn't take duals to hear a v8... I'm running long tubes into 2.5 tube, into a Y pipe with single 3" into the biggest flowmaster muffler i could find, turn down in front of rear axle. Quiet when cruising (you can talk or hear a radio) but it lights up under load. No cat for now, though I understand that's not the greatest thing for air quality.

 

I got lucky. A buddy of mine replaced entire exhaust on a 2013 z06 vette. Gave me the factory stainless steel cats.

 

Running punched out factory cat on mine. Still passes emissions sniffer test but this will be the last year its required.

 

Hmmm...how do you think it would sound without a muffler if I did Y-Pipe into 3" turndown in front of the rear axle?

Would I only need to buy one cat then?
