From what he hears it flows pretty good, but still prefers the factory unit at over 3 times the price.
For $550 it's affordable. One of my cats has rattled loose internally and needs to be replaced. Has anyone just repaired their existing pipes with a matched set of cats?
I understand that a single cat back without crossover is a no-no unless one has at least an Evo 2.5L to push the exhaust out hard enough to prevent backdrafts.
Is Mario Langston on this list? His website ( www.vintagesportsracing.com ? ) used to sell an aftermarket cat with dual cats and cross-over. There are pictures. Was it a DEC unit? Is Fillipo on this list? My ///M3 is also painted conspiracy theory Hennarot.
Looking for a catalytic solution - hope to hear from you guys.
