Well, after saying I wouldn't do it, I ordered up and installed an aftermarket muffler.
Yep, a "Nameless" axle back unit arrived 6 days after I ordered it (pretty darn quick - huh).
I got the version with the 5" mufflers (thank goodness).
It's was a breeze to install. I WD-40-ed the two nuts and shot up under the rubber hangars with a "hot shot", a mixture of hot water and dish soap. I had a syringe left over from my days of experimenting with chemical compounds.
OK, after trying to get my tri-focal glasses to cooperate, and my arms to bend in un-natural ways, while lying on a cold, damp concrete floor, to get the old muffler off the hangars ..... I decided to take a coffee break.
I put the keys in the ignition, packed up the new muffler and drove up the road to my favorite automotive shop, where they put the car on a lift, and swapped out the muffler, while I had a cup of coffee and read part of a car magazine.
How does it sound? Just great, for a boxer-4. I'm sure glad I didn't get the muffler delete or the 4" muffler versions. I growls a bit upon acceleration, but quiets down at cruising speed.
I'm happy
....... and mrs humfrz is totally impressed ....
