Our system leaves the stock primary cats and eliminates the secondaries. We can offer hi-flow secondary cats for those that want to keep it as stock as possible for emissions.

The reason we did not do a manifold back system is the additional cost and lack of benefit it would've brought. The stock cats are a very efficient design and will outflow 99% of crossfires out there. The additional cost of adding cats and flanges would've added another 400-500 to the total and brought maybe 1-2 HP.

Our goal is to provide an affordable alternative to the single cat back systems currently available.

We will most likely be building 10 systems, 5 SRT and 5 NA.
