Does anyone make a downpipe to replace the precats and bolt to the main cat? I see plenty for t2s but none for N/A.

There are no downpipes for NA because downpipes are for turbos only. However, Racing Beat and Bonez both make a "downpipe w/ presilencer" to eliminate the cats...I had a race pipe(downpipe & presilencer) on my NA motor a while back...good gains, but headers are better...

Well, I mean something that would connect the manifold to the main cat. This is for my daily driver and most muffler shops around here won't remove the cats. I am not really looking for all out power. I just want to get rid of the precats before they plug up and f*&k things up.

RX7.COM has the BONEZ PIPE that will do just that.
