Anyone heard TSP rumbler catback on an LT1 before? I was looking for sound clips and only came across LS1 sound clips with the rumbler exhaust. I'm highly considering this catback and was curious to hear some opinions about it. BTW I'm running kook's headers and their 3" ORY with a flowmaster muffler welded into the stock exhaust. What kind of gains would I see switching to a 3" catback if any at all?

ive heard it on an lt1 car, its almost the exact same as a loudmouth just toned down and slightly deaper
going three inches will well benefit ur car , u wont c much maybe a 5-10 hp increase but combined with headers and cai u gain a whole lot, some say anwhere between 15-30 on headers alone

ull like teh exhaust its not to bad , but goign with lt and ory might be a little too much b/c it will get raspy and loud
