"Positive HP & TQ Gains - SVT Cobra?"

[SVT30]

Well let’s see . . .

Bassini, BBK, Borla, Dynomax, Flowmaster . . .

Then there’s “X” versus “H.”

Some review sites complain about raspy sounds from some cat backs, as well as excessive noise. I don’t want the local constabulary either hunting or finding me because of overly load pipes.

So . . . which cat backs provide improved HP & TQ while improving exhaust note, but aren’t too noisy doing so?

Also, do you guys agree with the scavenging effects and so forth brought on by X pipes?
