Nice fitup there. Get those videos up of the exhaust note on youtube already. Would love to hear how that sounds. Especially if you have a before and after.
I've been a fan of Thrush as well and they have a perforated core in stainless steel as well but instead of the squared off cylinder like that it curves into it. Longer body length though 25" in total vs the 20" like on that magnaflow.
Either way I'll stop before I ramble too much. I like em though, almost a shame to hide them cause they look kind of mean against that matte olive.
Wonder how many buzzards worth of power you'll pick up with them. Surely there has to be a equine to avian conversion out there.
