Lake Pipes for Chevelle

[richrides]

Are there any places that sell a system where there are two diffrent ways for the exhaust to go? off the headers it could go either out side lake pipes or out the back. If you want it to go out the back you just cap the lake pipes if you want the exhaust to come straight off the headers then uncap the lake pipes. Are there any systems like this that would be suitable for a chevelle

sounds pretty interesting, but in all my browsing around car places online I haven't seen anything like that. I haven't exactly been looking, though.
