Sounds really good. Mufflers?
an old set of 3 inch corvette side pipes
Sounds great and glad to see your adventures now that the engine is treating you well
Now that the car is settled in and doing well, you might find some power with a traditional style exhaust. The sidepipes sound and look cool the way you did them, but a clean 3 inch exhaust with an X or big H and a set of modern mufflers can free up mid range on a street stroker. You may not need as much with a stock stroke engine but sidepipe cores often steal significant power.
Always easy to spend someone's money,
but I really liked the Borla ProXS on my Mustang and recently the Jones Full Boar on the truck. Quiet-ish poking around down and a real nice bark when you hit it. I did an H on the Mustang and an X on the truck based on how things fit. Hard to do on the unibodies compared to the truck, but a big smooth exhaust with mufflers as far back as you can helps too.
