Hmmm...
I'm a little worried about the Gibson exhaust vs. the Nissan one. For one, the clearance to the spare is a little tight for my tastes - I have a 32" under there, and it would hit. I'm also a little leery of the welds and such on the Gibson, as it looks like it's ripe for rusting in that area?
As for the tip of the exhaust, yeah, that seems quite long! I'd trim it back a touch too...
I think I'm gonna go for the Nissan exhaust.
