I dynoed 441rwhp with the gmmg.I replaced that with the stock ws6 catback and a E-cutout.Anyone have an idea of the power difference from cutout open to closed,through the stock ws6 catback.Any dyno data on the ws6 catback would be great

i doubt the differences would be huge, i mean the GMMG flows pretty well doesnt it? probably not worth the money for dyno pulls thats for sure. lol. if i had to guess the ws6 catback probably loses 10-15 over the gmmg, then the cutout gains back 15. so maybe you'll be slightly ahead in the end with the cutout open
