Deep tone
This is a great exhaust. Fit and finish was excellent. There were no instructions. I had to get a couple washers and nuts so I could install the connection at the end of the scuba delete. I reused the springs and bolts with new washers and nuts so it would flex. I also used high temp permatex copper instead of the flat gaskets. the tone on this thing is deep and I can still hear my CAI sucking over the sound so it's not too loud.
