Not sure what an Abarth style is in this context. If it’s the 4-tip GT style probably not.
We’re free to use any exhaust of course. There’s an EMPI single tip setup that puts the tailpipe in the exact right place for an MG TD. Works fine and relatively quiet. It’s not ideal for horsepower though so if you’re running a hi-po engine consider other options. The A-1 Sidewinder is about the best but I’m not sure how well they fit on our cars.
