is not a presilencer is a catalitic converter. have a tube that goes to the manifold and only have a single cat. just eliminates the two little cat. and is reliable.

They also have a connecting pipe that eliminates all cats, but it makes it real loud.... I had the highflow cat from Boonez in my 82 and went through emissions and passed with flying colors..

I have the cat w/ the presilencer (the kit that connects to the stock manifold and the stock connecting pipe that replaces all 3 cats), it's very mellow sounding (once I sorted out the manifold exhaust leak) and I've been very happy with it. A little pricey, but when you look at the cost of OEM cats (and mine were shot) you realize that it's not that bad at all..
