just wondering if anyone has used these vibrant metal core cats, the vibrant part number is 7100 for the 2.25 they say it flows 40% better...any input would be appreciated...its this or the highflow ceremic core from vibrant as well that part number is 7001 ...and is using a cherrybomb glasspack as a resonator going to take power away? I'm debating on buying that or the vibrant resonator, and has anyone used the ultra-quiet resonater from them (part number. 1140)?. Just some info... i have a magnaflow cat back with 2.25 ss pipes, and a pacesetter ceramic coated header (4-1). if you have any input on better parts i would appreciate that as well if you have the part number so i can do my own research on it. I searched the posts and found nothing on the metal core cats or the ultra quiet resonaters ....sorry about another exhaust post...


i have the m45 sc as well, but thought this as more of a peformnace question. which is why it's here.
