One of our new So. Texas Tbird Club members asked me in email this morning if I knew of anyone who has installed the Borla Exhaust System on their RetroBird. Since I did not, I put him in touch with our club members who do own RetroBirds to see if anyone has gone this route. There are, according to what I have read, several very good advantages to making this modification in the performance of that Tbird. Has anyone done this modification, and if so, would you share with us your thoughts on it? Here are a couple of links that I came up with.
