Bob,
you highjacked this post but that's alright with me.

My car had a fairly new, bone stock exhaust system when I got it. I don't know what I was thinking, but at the time we had a Bugeye Sprite and an MG Midget, both with this ANSA style end muffler, and both sounded fantastic, not too loud, but with the typical spitting noise when getting off the gas.
So I "stole" the best of those mufflers and put them on my car.

The car got noisier, but not to the point where it gets annoying, like on rice burners with truck-sized mufflers. The sound is actually beautiful, raunchy, but not as beautiful as I was hoping for. The engine makes the noise, and obviously British 4-bangers sound different from Italian ones (Alfa Romeo) and Swedish ones. Bummer.

Right now I'm waiting for a nice header to come my way, and then I'll start over with a straight pipe from there, and finish the exhaust off with a replica of the Abarth system that was sold for many cars, Volvos included, back in the 1960s . . . with one twist.

I'll have a large end muffler, mounted like the original one, but with 4 small diameter (2 sets of 2) end pipes. Moss motors sells a muffler like this for TR6 models, and usually 2 of the pipes (one either side) are plugged, meaning the TR6 has only one set of dual end pipes, left or right, depending on what country they sell the car (RHD or LHD). I'll have 4, like the 1950s and early 1960s Porsche 356 Abarths and Carreras. Note that these pipes are really small, about 1-1/4 inch in diameter, times 4.
