Mufflers, Ford Mustang GT/Early Cobra "Power-Flo" (pair)
Get maximum flexibility from your modular SLP cat-back system with our new PowerFlo™ low-restriction mufflers. Designed to provide an optimal balance of flow and noise attenuation, they employ a "straight-through" configuration that significantly outperforms traditional chambered and turbo-type designs. All PowerFlo™ mufflers are constructed from hand-polished stainless steel and embossed with the classic SLP logo.


ps... lowering springs

Go in the AM section on this site, and ask AMNick. I'm sure he can find out if the powerflow's are quieter than the LM2s, and if they are chambered (although if SLP.com says they are straight through, I'm sure they are just that).

Compare the 99-04 catback to the axle back for the S197. The axle back is listed as a straight through...
