Car chemistry inserts
Hey Farhad.
Any chance you did a before and after HP (even butt dyno) test with those mufflers? This might be apples and oranges, but I welded a two-disc car chemistry insert into the cat replacement pipe on my Spec Miata, and it dropped the sound from 95 to 90dB but at the cost of 4 or 5 HP. Doesn't sound like much until you figure that 5 HP is 5% of the total available.

If you call them they will make any sizes/length you like. You can have up to 3 inserts inside for the sound. Mine are 3" in/out about 15" long (I think). They come ceramic coated
