[W126 Coupe] Exhaust Opinions

[Mike R.]

Powder coating takes place at around 400F. Putting it on an exhaust that can 
get in excess of 1,000F is a waste of time since it's coming off the first 
time you drive the car. It's Jet-Hot or some other ceramic process only for 
exhausts.

Keep in mind that the 380 is seriously underpowered in our 3,800 pound cars 
and putting in a fabulous (e.g., expensive) stainless exhaust system really 
isn't worth it. If you're planning on keeping that car for the next 10-20 
years, then fine, but you'll never have sufficient power with that V8 in the 
car. If you're planning on upgrading to a 560 engine eventually, then do the 
good exhaust.

Later,
Mike R.
