Default Oval exhaust systems

Where can I find a complete, at least to the mufflers 3" oval exhaust system? I'm thinking I may have to come off the collector with some sort of round to oval adaptor . Can go back to 3" round after the mufflers. This is for a 70 GTO.

Perfect fit for the system on my 70. Was easy to install. I did go with 2.5" mufflers and tails after the X pipe. system really fit nice when installed.

If I did this again I would change nothing. I like the fit and sound. Install the tail pipes and mufflers, and then the center X where you want it. Then cut the 4 pipes to length and tack in, remove and weld fully. I used band claps from the connection on the headers and also a good solution for me.

I did pretty similiar setup to Paul E. Exhaust shop thought it was really easy to install and tucks up nice. I went with the Spintech 8000 series muffler though. Its their truck/rv muffler (20" case) so relatively quiet on the highway but sounds mean when you get on it

I'm looking for a 3" oval system for my 68 Firebird. Clicking on the Ram Air link comes up Not Found. Any ideas or other options for oval systems? Thanks
