First post here, I have a Roush catback and stratified 7.1 crackles and pops tune for the past 5k miles. Past few hundred miles ive notice the exhaust note slightly
changing, as in a little rasp above 3500rpms. Stock downpipe, perhaps I am breaking up the stock cat? All numbers and gauges read normal and car acts normal, just
the exhaust note is changing in the higher rpms. What say yall? oh yea 50k on the car so far.
