"I've had an 'X-pipe' on for 15 plus years daily driver only vehicle. Presently the power plant is a 235, 848 head, Fentons with the X and two 30" glass pack mufflers. The main reason why I did it was to quiet down the rap I had with deceleration and it has worked beautifully."
Cosmo,
A quiet exhaust note from a dual system is the reason I run an "H" pipe on the vehicles I have with home made dual exhaust systems. One "performance" benefit comes from the dual system breathing freely and the other performance benefit is a quiet vehicle that's more pleasant to drive. It seems like an exhaust system addition that has no down side. Because exhaust tubing welds so nicely it seems like an easy home shop project.
By the way, what is ODSS?
