I put a cat bypass on and was thinking about an exhaust for a little better sound but I want the ability to go back to stock since it was totally unmolested when I bought it so my options on tinkering are somewhat limited.

Any exhaust recommendations out there, I'm amazed at how quiet the car is, I had a GHL and cat bypass on the 87 and loved the sound.

Thanks guys
Go the exhaust route first before boost. The engine will not be as stressed because you are making it more efficient by reducing the backpressure on the turbo instead of cramming more pressure into the intake to get the power. Plus you can lighten the rear end of the car and make it louder at the same time with one of these high flow mufflers. You can always go bak to stock too.
