cats were replaced by straight exhaust, running anti fouler O2 extenders on rear O2s, kept stock center muffler into two high flow resonators then replaced kinked up stock over axle pipe with normal round pipe and then two small resonator mufflers at rear , sounds deep with no drone and only loud when your wide open.Tips are 70s Olsmobile 442 trumpet tips, Total cost parts and labor was $650 US
so far driven couple hundred miles and no codes. Still slow but sounds good now. :-)

 

I think we'd all like to hear a sound clip.

 

Definitely need a video! Possibly even a drive by or two!

 

Was by myself so couldnt get any fancy stuff
this is couple revs with car backed up to garage door.


this inside car,couple revs with windows open


this is a short 0 to 60mph run windows down but top up,
phone in its holder on center console.

maybe on the weekend if my girlfriend is willing I can get some better ones.

 

I have a similar setup, factory cats, straight pipes, and rear Mina mufflers, does not sound at all similar, mine is more raspy, sorta interesting. Looking to get NP high flow cats eventually if I ever have a ridiculous amount of money to waste.
