I was lucky enough to get my hands on a mint red 1990 ZR1 w/15K miles black interior - I love it! My other toy is an ATI Pro Charger supercharged 2002 black Trans AM WS6/LS1 – running 8lb of boost - another rocket.The only thing I don't like about the ZR1 are the exhaust tips and lack of muscle car sound. My Trans Am has the adjustable Borla cat back and it goes from a rumble to obnoxious sound - depending upon the plates in the exhaust - I like that!Since I'm a little tight on funds right now (after springing for the ZR1), I'm not sure i can spring for an entire cat back for the ZR1. I guess I'd like to start with either exhaust tips, or, possibly muffler + exhaust tips (stainless or chrome) for a little more sound and to finish off that wide butt on the ZR1! I think I’d go for the muffler+tips if I can find a fit. I think the inlet pipes on the stock ZR1 to the muffler is 2 3/4" ?Can anyone please give a newbie some recommendations ranging all the way from strap on exhaust tips to replacement mufflers with nice tips?Thanks in advance for helping a newbie
