How does this (exhaust sound quality) compare with just a plain X-pipe (e.g., Supersprint X-pipe) without the secondary cat (catalytic converters) being deleted? Anyone have the chance to hear and compare both (plain X-pipe vs X-pipe+secondary cat delete) at the same setting?
I am thinking of just The SuperSprint X-pipe to replace the resonator but leave the secondary catalytic converters because of stricter AQMD (Air Quality Management Department) requirements in California.
