Quite a few guys have Flowmaster cat backs around here. I know Carl (Wicked03) and Andy (cobravenom39) do.... Im not a fan of the usual flowmaster sound, but they sure do sound sweet down low.

And as far as HP gains, it may not make the most, but not enough of a different to notice with the SOTP meter...... just go for the sound you like the best :biggthump

Yeah I have the Flowmaster Cat back.... I bought it originally because I love the Flowmaster sound, but the flows seem to sound a little more hollow on the 4 valves for what ever reason. Still sounds great, but not the same as they used to.

If I could do it over I would probably get the magnaflow since they are stainless steel.
