What Catalatic converters and headers do you recomend?

[Braves dude]

I have an 87 Blazer with a rebuilt 350 motor. I will be running a true dual exhaust what Cats and header do you recomend to pass emissions.

proven fact of good shorty headers and 2.5" down pipes to http://www.summitracing.com/search/...r-Scavenger-Series-Y-Collectors/?autoview=SKU then high flow single cat and 3" in/out muffler or 3" in and 2x 2.5" outlets . this will get you 30-40 hp at the rear wheels alone.

also this makes it so easy to stay clear of t-case on pass side and also fuel filter on pass side from heat.

and if your state requires testing then stock routing is required and NOT 2 cats. better check first.
