I've seen the Mild to Wild for the C6's, does anyone make this exhaust for the older generations of Vette? C4? Specifically 1985?

I haven't seen anything like that for the C4. But you can do alot with your C4.You can gut the precats and remove the cat converter. Also there is alot of nice sounding exhausts out there for the C4. I have seen tunable exhaust setups.Check some of the mail order cats.
