I've seen all of the these posts about the '08 Maxima with the DE engine, but nothing about one with the HR. I'm not sure what's going on the VIN clearly shows it as an HR car, but I can find no info about it. Plenty on the 350Z with this engine along with other makes/models though. Can someone point me in the right direction? I'm looking to upgrade the exhaust from the block all the way back. Not sure of any differences there may be between the two types?
