From the engine back (STOCK) there is...

Precat - Maincat - (Pipe?) - Muffler

A Downpipe replaces the Precat
A Midpipe replaces the Maincat (straight through no backpressure)
A HighFlowCat replaces the Maincat
A Catback replaces the Muffler (from the Maincat back).

On a 300-350 rwhp car, how much power is the mid-pipe no-cat mod worth? Does a high flow cat like a Random Tech remove most of the restriction?

Thanks,
