MagnaFlow now has an X-Pipe for the S197 Mustangs with catalytic converters (cats). Increase flow and relieve some backpressure, all giving you more power as well as generating that distinctive sound. MagnaFlow found 10 rwhp on an automatic equipped car, simply by replacing the OE parts with their high flowing replacement.

Once again in going over what I wanted to achieve and the budget to be spent Don steered me in the right direction. These X-Pipes coupled with the CAI and program makes for a fun everyday car that sounds just right. Saved $'s over buying axle back systems that don't provide the performance and sound enhancements that these X-Pipes do. I never thought I'd have strangers just walk up to me in a parking lot and tell me how good my car sounds. Thanks Don.

Weak Cat cores?
One of the catalytic converter cores became dislodged and migrated down to the drivers side exhaust tip where it got stuck. Local exhaust shop had to retrieve it. Said hey'd never seen that happen. Fluke? Otherwise no issues, great fit and sound/flow gains. LOUD with my cam.

Working with Don, he recommended this piece knowing what I wanted and the budget I was working with. The X Pipe combined with my CAI / Program and lower pulley creates a totally awesome ride with a sound that makes axle back muffler a no need add. Recommend the hi-flow cats BIG TIME!
