Info

Ok not sure if this a crazy question or what. But I have race pipes instaled on my e92. But looking to tone it down a little bit drone mostly. Now dose it make any sense to put the stock cats back on by welding to the pipes. Or add two more resonators and go with the quad resonator set up. will any of these make a diff or is my only real option HFC. Thanks for any info
