Off topic.....

Brian, I would run back to Lowe's and exchange that "turf builder" for "bonus S for southern lawns".

I've used both, Bonus S is worth 10X the cost of turf builder.

I treated the lawn a month ago with Bonus S. The iron does wonders. This time regular stuff. Net time is back to Bonus S.

HP and TQ will be increased by reducing back pressure. If you do so I would also find an airbox to get more air in. That will increase the benefit of the reduced back pressure. The best performance exhaust systems are engineered by application and performance numbers are stated. If at all possible that is the route I would go.
