Looking at fitting a flowmaster 40, twin in twin out. Anyone have one of these? Thanks

 

I had a big block 50 on mine for a while. It did sound great but also did drone a bit on the highway. Only reason I took it off was a scored a new old stock GM Performance Parts (Borla) full stainless cat back setup.

I have a 40 on my GMC truck and my wifes Tahoe. Both 5.3 (basically same engine just slightly smaller displacement). Both sound great.

 

Thanks, just want something with a bit more rumble than stock.
