Any opinion for that application. Are you running dry or wet exhaust? Wonder if the springs could be changed out top opon quicker or will relax some over time? Was your performance affected?

Theoretically, one could keep them in a partially to a full open position via spacers (or other methods) to adjust the sound level at lower speeds?
How loud would they be in the full open mode at idle?
These could be fun

Do you have some downward pitch between the tops of the elbows and tailpipe exit?

We'll put a level on the tailpipes to check the down pitch. Will CMI do work on Stellings tailpipes? They once told me they work only on CMI products.
Thanks!

So I have 4 of these but changing from SC engines to NA. I was told by one person I should use different mufflers on my NA motors. I really dont want to spend $2000 on new mufflers if these would be safe/fine for my new application.
